Rotor Walrus (born 3219) is one the main protagonists in the Sonic the Hedgehog comic book series and its spin-off comics published by Archie Comics. He is a Mobian walrus and was a key member of the Knothole Freedom Fighters, using his skills and knowledge of technology and mechanics to provide the Mobians with an edge against the former despot Dr. Ivo Robotnik and, since his demise, the forces of Dr. Eggman. Following Sonic the Hedgehog's return from outer space, Rotor limited his involvement with field operations and stuck to providing data and technological assistance. In 3237, he was voted in as a member of the new Council of Acorn. However, when Ixis Naugus' manipulations resulted in NICOLE being unjustly banished from New Mobotropolis, Rotor immediately resigned from the Council in disgust and returned to full field duty as the leader of the new Team Freedom.
Rotor’s initial comic design was based primarily on that of his counterpart from the Sonic the Hedgehog pilot episode; the later changes made to his color scheme and general appearance on the television show were never adapted. As such, he is generally larger than most of the cast and has violet fur, peach skin on his front torso and muzzle, and darker toes and fingers; he wore a teal bandolier-like tool belt and a backwards yellow cap. Like many in the comic’s early days, Rotor started off with light blue eyes; they’ve since been established as green.
As a child, he wore green overalls. He briefly sported a wool cap, shirt and large medallion, but his biggest shift in design came with the addition of glasses, a brown bomber jacket and a slight tuft of hair. For a short time he wore a neck brace. Aside from his everyday outfit, he was sometimes depicted in his blue and red Council of Acorn uniform up until his resignation fro the council. As "Iron Rotor", Rotor is clad in his nanite battlesuit, a yellow and gray outfit that covers most of his body. The helmet is separated from the rest of the suit, and is fitted with a transparent visor.
Early Life and Family
Rotor hails from Walrus Island in the North Sea where his family was part of the Walrus Herd. His father, Sherman Walrus, was a veteran of the Great War, serving as a member of the Royal Army along side Jules, Bernadette and Sir Charles Hedgehog as a driver for their troop. Along with Rotor's mother Georgette Walrus, Sherman had relocated from Iceborough seeking a better life for his family. Rotor was in Mobotropolis for educational purposes during Dr. Ivo Robotnik's coup d'état but was evacuated to Knothole Village along with the other children in the city. His father perished while resisting Robotnik's takeover, while his mother-then pregnant with his younger brother, Skeeter Walrus-returned to the Northern Tundra. Inspired by the Original Freedom Fighters, Rotor joined with Sonic, Princess Sally, Antoine D'Coolette and the young Miles "Tails" Prower to form the Knothole Freedom Fighters after the original group's demise. His fascination for powerful weaponry-a result of having grown up listening to his father's stories of the Great War-coupled with the sometimes disastrous results of his engineering efforts, earned him the nickname "Boomer."
Knothole Freedom Fighter
When Sonic learned that Robotnik had allegedly developed a powerful bomb (it was really a bug bomb to deal with a pest problem), Rotor joined Sonic and Sally in tricking Robotnik with a phony protest, before disguising himself as Robotnik to steal the bomb (an easy task due to his size). Unfortunately, Robotnik had the idea of disguising himself as Rotor to trick the Freedom Fighters, but the mix-up was quickly resolved. Later, he and Sonic traveled the southern regions of Mobius, where the two witnessed the helpless Bunnie Rabbot captured by two SWATbots to be roboticized. Although Sonic went to save her, he was temporarily stopped as he was attached to Rotor by tether. After rescuing the partially-roboticized Bunnie, the two brought her back to Knothole Village where she became a member of the Freedom Fighters.
When Sonic was amnesia-ridden and convinced by Dr. Robotnik to attack the Freedom Fighters, Rotor's security systems detected the micro-transmitter placed on Sonic to provide the location of Knothole. Rotor attempted to keep Sonic out of their secret hideout but was bypassed by Sonic with relative ease. Eventually Sonic's memory was restored and the device removed.
Rotor later developed the "Neuro-Overrider", a device which would allow a Mobian who was roboticized to maintain their free will. Sally hoped to use this to allow herself to be roboticized so she could then infiltrate Robotropolis and steal a roboticizer to learn how to reverse its effects. The Neuro-Overrider fell off Sally as she was roboticized however and she was robbed of her free will. She was safely restored to normal by Dulcy the Dragon.
Search for the Herd
After receiving a distress call from his mother in the Northern Sea, Rotor piloted his Bathysphere and travelled there to see what was wrong. Upon his arrival, Rotor discovered his family and the entire Walrus Herd had been placed under mind control from a Neuron Bomb by Dr. Robotnik. When he discovered that Robotnik was hoping to freeze the entire planet, Rotor attempted to escape and warn his friends, but was knocked into the ocean by an Icebot. He was quickly rescued by two of the Arctic Freedom Fighters, Sealia and Augustus. The three then managed to infiltrate the Walrus Herd and Rotor attempted to free them of their mind control. However, the entire Herd attack Rotor, though Sealia and Augustus managed to save him and bring him to safety. Rotor vowed to return and liberate his family from Robotnik's mind control.
Continued Battle Against Robotnik
After the Knothole Freedom Fighters (except Sonic) were infected by a biochemical weapon from Robotnik, Rotor managed to inform Sonic of what had happened before falling unconscious. Sonic used the Shrink Ray to become microscopic and go inside Rotor to assist his Aunti Body in the fight against the French Frirus and Paris-Site. Sonic was successful and Rotor and the others recuperated.
Following this, Rotor attempted to de-roboticize Sonic's Uncle Chuck. Despite his efforts, Chuck remained a Robian.
Not long after this, Rotor created a remote which enabled the Freedom Fighters to travel to the Zone of Silence and locate Sally's father King Max. However, due to King Max being under some sort of spell, the Freedom Fighters are unable to retrieve him and are forced to return back to Mobius Prime.
Some time later, Rotor sat on the council to review Sonic's idea to use the Neuro-Overrider and allow himself to be roboticized. Rotor objected along with the rest of the council, saying the idea was too risky. After Sonic was captured by Nack the Weasel and roboticized, Rotor helped prepare Bunnie to defend the village against Mecha Sonic. After Bunnie was defeated and Knuckles the Echidna was knocked out, Rotor managed to catch the Echidna in a net during his fall. As Knuckles came to he suffered from delusions, and attacked Rotor as he thought that (due to his weight) he was Robotnik. Sally managed to knock Knuckles back to his senses however and the fight continued. Rotor oversaw the Neuro-Overrider used on Knuckles to allow him to keep his free will while becoming Mecha Knuckles to combat Mecha Sonic. After the battle ended, Rotor worked with NICOLE to transform the damaged Mecha Sonic back to a Mobian.
Weeks later, with the help of Rotor's Neutralizer, Sonic travelled to the Zone of Silence and was able to finally rescue King Max from the Zone of Silence. Following this, Rotor worked with Dr. Quack to create the Dream Watcher so that they could look into King Max's mind and bring him out of his comatose state. Sonic managed to do this, though King Max remained in his crystallized state.
Days later, Rotor revealed his new weapon to Sonic, the "Party-Hearty Quadra Sonic Rock 'N' Roller", as well as his Remote Scanner. The same day the Freedom Fighters found themselves working with Knuckles the Echidna to fight Anti-Knuckles and Anti-Sonic. They then went to Anti Mobius where they discovered Dr. Ivo Robotnik stealing the energy from the Sunken Island's Chaos Emeralds. After Robotnik was transported back to Mobius Prime, Rotor was disappointed he never got to use his Remote Scanner during the ordeal.
During Operation: EndGame, Rotor was in Knothole when Dr. Robotnik arrive on the scene. Saying "Robotnik in Knothole? Not in this lifetime!" he attempted to blast Robotnik with the Party-Hearty Quadra Sonic Rock 'N' Roller. Robotnik managed to phase out the gun's blast and destroy it, taking the entire village hostage. Rotor and Tails later managed to sneak into the sewer system, but were caught trying to escape by Combots.
Return to the Herd
With the death of Dr. Robotnik caused by the Ultimate Annihilator, Rotor decided to return to the Herd. When he arrived back he was relieved and astonished to find that the Herd had regained their free will as a result of the Ultimate Annihilator firing. He spent several weeks with the Walrus Herd, enjoying time with his mother and younger brother Skeeter. However, while there Rotor was unaware that Robo-Robotnik had travelled to Mobius Prime and replaced the late Dr. Robotnik. Thus when the herd suddenly came back under the mind control spell, Rotor did not know what was going on. Hiding out in his Bathysphere, the Herd managed to damage it and cause it to sink. Rotor was rescued by the Arctic Freedom Fighters, who informed him that Robotnik had returned.
Activities Against Eggman
Returning to Mobotropolis (as he was unaware it was re-conquered by Robo-Robotnik), Rotor found himself meeting up with Mina Mongoose and shortly afterwards Sonic. The group returned to Knothole and Rotor began attending Knothole High School along with his other Freedom Fighters.
After the Freedom Fighters learned the Sword of Acorns could restore Robians' free will, Rotor asked that they could use it on the mind-controlled Herd to restore their free will as well. Returning to Walrus Island, Rotor planted a bomb on the Walrus-constructed Oil Rig while Sally used the Sword of Acorns to restore the Herd's free will.
During Sonic's year in space, Rotor stepped up in the war against Robotnik by building even more powerful weapons. Unfortunately, his efforts led to not only the destruction of robots, but also to the injury of his fellow Freedom Fighters, including Larry Lynx. Horrified by what he had done, Rotor resolved never to construct another weapon, though he later assisted in the construction of the Metal Sonic Troopers to defend Knothole. He would later come to feel that this decision was a betrayal of his vow, though he also realized that he had perhaps gone too far in his efforts.
Rotor continued to help his friends in any way he could, even acting as a quasi-mentor to Tommy Turtle, helping him become acquainted with his new life. Unfortunately, this relationship came to an end after Tommy was enslaved by A.D.A.M., resulting in his death under the guns of the Egg Fleet.
Rotor was also one of the many citizens captured by Eggman during the destruction of Knothole, though quick action by the survivors of the attack resulted in a successful rescue mission. However, injuries to his back (caused by him shoving Tails free from beneath a collapsing roof during the destruction of Knothole) left him unable to participate in Freedom Fighter activities for some time afterwards.
Rotor was elected a member of the new Council of Acorn, a group of six elected members and King Elias established to bring about some much-needed political changes in the Kingdom. Rather than get a break from the stress of combat, however, Rotor found himself in the middle of an even more dangerous situation: Knuckles' arch-nemesis, the Chaos Emerald powered entity called Enerjak, had been reborn thanks to the machinations of the Dark Legion scientist Dr. Finitevus and was intent on conquering Mobius. He and the other council members were informed of the issue by Dimitri, but voted against taking action until more information could be gathered. Fortunately, the matter was soon resolved by the efforts of Sonic and the Guardian Locke.
Later, while attending to Freedom HQ, Rotor was attacked by his Anti Mobius counterpart, Boomer, who mocked him for not being able to defend himself. Rotor was brought to tears when he was unable to help defend Freedom HQ from the Suppression Squad as a result of his neck injuries. Instead, he fled the scene to contact the Chaotix about the situation and later voted to send a mission to retake Freedom HQ, only to be outvoted by the rest of the Council. He later assisted Sonic in traveling to Moebius, an order given by Sally that later brought the Walrus to her defense when she was put on trial for defying an order the Council had given regarding Sonic. He would later provide backup for the Freedom Fighters and Chaotix in the final push against the Eggdome; after the Egg Phoenix was destroyed, Rotor erected a force field generator so the Freedom Fighters could call it a day, but he failed to get any sleep himself and instead readied the visual link to New Mobotropolis. He later stayed behind while the others went on the final assault, and after Sonic managed to defeat Eggman, Rotor helped transport them home in his jeep to celebrate their victory.
Their victory was cut short as the Iron Dominion took over the empire, which the Freedom Fighters would learn from Monkey Khan. When the Iron Queen took control of NICOLE and thus all of New Mobotropolis, Castle Acorn was sealed shut, trapping the royal family and Council of Acorn within. Rotor was later revealed to have been taken prisoner and was among those brought to the Coliseum for public "legionization" -- a process that forcefully converts a Mobian into a brainwashed Dark Legion cyborg. When Rotor was brought out before Snively, who was in charge of the operation, he angrily reminded the Overlander that they had worked together in the past; smugly dismissing this, Snively was caught by surprise when Rotor suddenly attacked the Legionnaires holding him, subduing them simultaneously before lunging at a terrified Snively. Unfortunately, Rotor's heroic efforts were quickly halted by his injured back flaring up. Fortunately, Amy Rose, Antoine and Geoffrey St. John soon appeared, and Amy destroyed the operating table to which Rotor was being dragged, scattering the villains and saving the walrus.
Final Time Saving The Herd
With the threat of the Iron Dominion ended, Rotor and his fellow council members set about revising the new constitution of the Republic of Acorn. As such, Rotor did not accompany Sonic and Sally to become a member of the Wolf Pack Nation despite having been invited. Just as Sonic and Sally helped resolve a crisis there, however, Rotor was informed by Hamlin that the Arctic Freedom Fighters had called in with news that a Dark Egg Legion chapter had captured the Walrus Herd.
After learning of the situation, Sonic invited Rotor to go along with him, though Hamlin was quick to deny the Hedgehog's request, and Rotor agreed that he planned to stay in the city. However, after having NICOLE meet him at his house, he informed her that he had every intention of going to aid the Herd, requesting that she construct a suit of armor from the nanites for him. Departing, he flew to the Northern Tundra, contemplating his previous actions as a Freedom Fighter and determining that he would retire permanently once this mission was completed. Before he got to the battlefield, however, he was dragged out of the air by Silver the Hedgehog, whom he engaged briefly in battle only to find himself helpless. Silver then accused him of not being "Boomer" Walrus, and then of being a traitor to the Freedom Fighters. Silver attempted to short Rotor's battle armor and use his telekinesis to halt him, but when Rotor explained what was at stake with the safety of his Herd and the Tundra area as a whole, Silver agreed to help him. When they arrived, they quickly found Dr. Eggman's nearby base, and found a neural interface Eggman could use to control the herd personally. Silver used it to send a psychic pulse, breaking the Herd's mind control and also scrambling the Orca members of the Dark Egg Legion in the area. Silver later said he also sent a signal that would forever block the Walrus Herd from future mind control attempts. He also figured out for himself that Rotor was indeed "Boomer", but the information he had about him was out-of-date.
Naugus and NICOLE
When Geoffrey St. John seemingly betrayed Sonic during a mission and went MIA, the Council of Acorn was unsure of how to respond, as they had no way of knowing if Geoffrey, leader of the Secret Service, was working on secret orders. Additionally, they were left to deal with ever-increasing public concern over NICOLE's control of the city. Unknown to everyone, these issues became tied as Geoffrey, working with Ixis Naugus, manipulated the public's fears of NICOLE in order to set Naugus up as a potential savior of the people and giving his bid to take control of the Republic of Acorn more sway. Rotor pushed his fellow councilors to discuss the issue with NICOLE, as the AI had been emotionally hurt by the public's increased fear and hatred of her, but when they were about to do so, Naugus himself arrived before the council, claiming the crown as rightfully his. Rotor was vehemently opposed to this, even going so far as to attempt to rally the other former Freedom Fighters among the council, but thanks to the wizard's ability to twist and amplify negative emotions, everyone soon began bickering with each other. Eventually, to Sonic and Rotor's displeasure, it was decided that the matter be dealt with formally and that Naugus be given a chance to argue his claim. However, all were taken by surprise by the unexpected launch of the new Death Egg Mark 2.
After a mysterious weapon fired from within the Death Egg, the world became awash in white. Soon after, Sonic found himself in a strange but oddly familiar setting; he eventually came across a prison pod and released those inside it, who introduced themselves as Sally Acorn, Antoine Depardieu and Boomer Walrus, having seemingly never met before. The group explained that they believed one Dr. Eggman to be responsible for several recent kidnappings, and Boomer added that he might be behind the increased number of earthquakes lately. Sonic agreed to help them hunt down the doctor. In the Marble Zone, they were attacked by Eggman's robots; Boomer captured and disabled a Caterkiller with his bare hands, impressing Sonic, and then set to reprogramming a damaged Buzzbomber, thinking it would be good to have the extra help. He did not want to stoop to Eggman's level and force a small animal to act as the robot's power supply, however, but Sally was able to get a Flicky bird to volunteer. This proved useful, as Boomer later used the Buzzbomber to airlift himself and Antoine to safety. Eventually, Sonic caught up to Dr. Eggman and fought him, forcing the doctor to retreat; Boomer was thoroughly impressed, and the group continued on to an underground tunnel they believed would lead them to the doctor's lair.
Return to Duty
In the aftermath of Eggman's Operation: Clean Sweep, Sally was roboticized, while Naugus took advantage of New Mobotropolis' fear of NICOLE, unwittingly caused by Mina, to save the city from a Titan Metal Sonic and usurp Elias as king. When the Council took a vote to exile NICOLE to Freedom HQ, everyone but Rotor voted to do so because it was what the people wanted. Rotor was so disgusted and upset by the turnout that he resigned from the council right then and there.
With Sally's roboticization, Antoine's severe injuries, and Bunnie's departure, the Knothole Freedom Fighters were forced to disband. However, Rotor, along with Sonic, Tails, and Amy, successfully convinced the Council (sans Naugus) to approve two new Freedom Fighter teams: Team Freedom, who would protect the city itself, and Team Fighters, who would pursue Eggman's forces. Rotor himself used a special power suit that circumvented his back injury and let him return to active duty.
As the leader, Rotor accepted Big the Cat, Big the Cat, and Cheese, and also rebuilt Heavy and Bomb, bringing the roster to six members. Though Naugus continued to dismiss the group's reliability, Team Freedom proved their worth when the community center collapsed due to an unseen attack by Tails Doll; with Naugus incapacitated due to inner personal matters, Rotor and his team sprang into action and successfully stopped the collapse, simultaneously gaining public support and discrediting Naugus. The team further distinguished themselves when the Death Egg returned to the city, launching Egg Swats and Team Metal. Bravely leading his new team, Rotor activated the shield generator only for it to be destroyed, and then assigned Cream to lead civilians to safety while the more seasoned members of the group continued fighting. Naugus arrived on the scene and attempted to prove Team Freedom's superfluousness with a blast of crystalline magic on some Egg Swats, only for his body to undergo a hideous and painful mutation. Grudgingly complimenting the wizard's skill in the hopes of getting him back into the fight, Rotor defended his unwanted king and called on Big to carry him to safety. He then went up against Metal Tails, and was able to destroy the robot after Elias-working with his new Secret Freedom Fighters-damaged the robot with a crossbow bolt. The team celebrated their victory, though Rotor came to suspect that they had been aided from the shadows.
Rotor's next task was nothing as dangerous-using his suit's ability to interact with the nanites, he opened a door with a broken lock affected by Larry Lynx's jinx. Penelope thanked him for his assistance, joking that he couldn't seem to stop working for the council between leading Team Freedom and working with the nanites. She asked him if he "unclog[ged] drains too" to which Rotor replied that he could and that he would just need to get Big so that he could use his fishing rod. Shortly afterwards, Rotor and the rest of Team Freedom attended a concert held by Mina Mongoose that was aimed at raising support for bringing NICOLE back to the city. When the stage unexpectedly collapsed-again courtesy of Tails Doll-Rotor and his team leaped into action to save Mina and her band, the Forget Me Knots. Rotor also rushed to Antoine's room at the hospital when Metal Sonic took him hostage, but arrived to find the robot gone.
Rotor later joined NICOLE at the ribbon cutting for the restored Castle Acorn, where he assured the AI that the people had no reason to distrust her. He also expressed gratitude at the absence of both Naugus and Geoffrey, though NICOLE chastised him for being so unkind given Naugus' condition. After learning of her efforts to complete a device created for the wizard's benefit, he remarked that she was too kind, but was then shocked as the castle began to crumble. He then asked whether the foundation was failing, but was informed that something was affecting the nanites. Cream then approached him with the theory that Tails Doll was behind it, though she was initially embarrassed by her convoluted explanation. Rotor was quick to praise her reasoning, and decided to put the theory to the test. Their suspicions were proved correct as Tails Doll, believing Team Freedom to be occupied, entered the city power station only to find the heroes lying in wait. Unfortunately, they were then forced to face the robot's true power as it used a number of reprogrammed nanites to create a demonic new form for itself. The monster's objectives were simple: destroy the power generator, allow Robotropolis' radioactivity to enter the city, and eliminate Team Freedom. However, the battle was cut short when he along with Team Freedom were caught up in a second Genesis Wave.
- Note: From this point, Rotor's history continues from his new life in the altered timeline.
Rotor is usually a very calm, easygoing and a bit clumsy individual, rarely showing aggression. However, he despises Dr. Robotnik and anyone who follows the latter's beliefs, and do whatever he can to oppose it, time and time again proving himself valiant and courageous throughout the war for their planet. He is very defensive of his family and friends, and stands as a trusted friend to everyone who knows him, willing to help them in any way possible. During Sonic's time in space, Rotor became vehemently opposed to the use of firearms due to accidents caused by weapons he had designed to help fight Dr. Robotnik in Sonic's absence.
Powers and Abilities
As a Walrus, Rotor is a bulky fighter with high physical strength, enhanced durability and an adept swimmer, and his endurance is top-notch as well. However, his greatest talent lies in his mechanical abilities. Rotor is a mechanical super genius, a quick thinker and very insightful, adept at creating tools and machines for use in the war against Dr. Robotnik and beyond, as well as deciphering new technology. He is known for his numerous creations that aided the Freedom Fighters early on. Some of these include the Bathysphere and the infamous Neuro-Overrider, which would theoretically retain one's free will even if they were roboticized. Rotor also assisted Dr. Quack in keeping the crystallized King Max alive by providing him with medical technology and later helped his patients Geoffrey St. John and Hershey Cat by creating nanites to destroy the nanoprobes Eggman had infected them with. Other inventions include the Party-Hearty Quadra Sonic Rock 'N' Roller and the Remote Scanner, as well as designing his own suit of nanite battle armor.
On a few occasions he has proved to be quite a marksman with firearm-like weapons as well, both with sniping and general marksmanship.
The Iron Rotor battle suit is probably Rotor's most dynamic invention. In addition to giving him the support to overcome back injury, it enables him to take flight and employ projectile weaponry against opponents.
Appearances in Other Media
Rotor made a brief cameo in the first and third bonus stages in Sonic the Hedgehog Spinball. Amongst other Freedom Fighters and Animal friends, Sonic can free Rotor from capsules. Once freed, Rotor (like all the other characters) flies away. Rotor is purple with a yellow cap, the same color scheme he sports in the Archie Comics series and the Sonic the Hedgehog television series' pilot episode.
Rotor appears in three of the Sonic the Hedgehog novels written by Michael Teitelbaum in the mid nineties:
- Sonic the Hedgehog: Robotnik's Revenge 1994
- Sonic the Hedgehog: Fortress of Fear 1995
- Sonic the Hedgehog: Friend or Foe? 1995
In these books Rotor fills the same role as in the comic and cartoon series, never being the main focus of the plots.
- By mistake, Rotor was named Boomer in the earliest issues of the Sonic the Hedgehog comic series. It was corrected in issue #6, as well as reprints for these early stories. However, in the letters page, when a fan asked the deal with Rotor's old name, it was explained that "Boomer" was actually a nickname the character had in his childhood; some stories depicting the Freedom Fighters in their childhood even have him addressed as Boomer. Ironically, this error later provided the basis for a Silver plotline, in which he found Rotor listed as Boomer in a record of the early Freedom Fighters and came to the conclusion that they were separate entities entirely. A further nod to this is that Anti-Rotor's true name is Boomer to distinguish himself from regular Rotor.
- In the book Robotnik's Revenge, Rotor is mistakenly referred to as a sea lion.
- Rotor's age is taken from the letters page of StH #46 where it is stated he was 16. Since the issue canonically took place two years ago, in 3235, Rotor's current age would be 18 since nothing has been revealed to contradict it.
- In Sonic the Hedgehog #148, Rotor reacts to Fiona Fox discovering a gun stating "The Freedom Fighters never use guns. Never have, never will.". However, this is a contradiction of his use of the "Party-Hearty Quadra Sonic Rock 'N' Roller" gun which he created. Sonic the Hedgehog #215 fixed this plothole by saying back in the olden days he used home-made guns, and it wasn't until he'd accidently injured fellow Mobians, such as Larry Lynx, that he vowed never to use guns again. This was further elaborated In the Sonic the Hedgehog: The Complete Sonic Comic Encyclopedia by stating he would contradict himself as a result.
- In Sonic: Evolution of a Hero, it is stated that Rotor helped in educating Tails to genius level intellect.
- Former writer Ken Penders revealed Oct. 30, 2009 on his message board that he considered Rotor to be homosexual, stating "I thought it was fairly obvious Rotor was gay, and begun laying the groundwork for that storyline during the Light Mobius segments. I even showed his life partner without saying as such and planted clues between the lines.".  This suggests that Cobar was Rotor's "life partner" in Mobius: X Years Later, which was confirmed on his message board. . Because of the fear of backlash over the relationship, SEGA ordered Ken to keep the relationship low-key, only providing subtle hints in the series as to the relationship. 
- According to Ian Flynn, this is considered non-canon, so it seems very unlikely that it will show up in any form. Since the reveal of this never appeared within the story and whatever clues there were are practically nonexistent, it seems even more likely that this character trait will not be brought up again.
- When wearing his battle suit during combat, he has a striking resemblance to the Bad-Box-Art Mega Man from Street Fighter X Tekken.
