Moves and techniques

Sonic the Werehog (ソニック・ザ・ウェアホッグ Sonikku za Ueahoggu?) is Sonic the Hedgehog's bestial werewolf-like form in Sonic Unleashed. This form was created when Sonic accidentally absorbed a large dose of Dark Gaia's energies, while the transformation itself would be triggered by nighttime and remain active until daytime. Due to this form's unique traits, Sonic the Werehog is essentially a hedgehog/Dark Gaia's Minions hybrid. Sonic later lost this form permanently when Dark Gaia reclaimed the energies that caused the transformation.

Concept and Design

Early art of the Werehog was made by a Sega member named Tanahashi. He changed Sonic's general form into something more strong looking. The shoulder and the head are connected by a single line, and his chest is much more broad, giving his body the appearance of an inverse triangle. The final design, he said, was a "silly design"; it was made when he was getting started with the Werehog. He based the design to that of a Yeti.[2]


In this form, Sonic resembles closely that of a werewolf. He grows slightly larger and gains more muscle mass and weight, with his torso becoming broader, his hands getting larger, and his arms growing thick, out of proportion, and muscular. Additionally, he grows sharp nail-like claws on his fingers, his teeth become fangs, and his muzzle becomes noticeably longer. His skin also turns light blue, and he gains lush and heavy gray/dark blue fur that also grows out in places where he did not have it earlier, such as on his arms and chest. Traits of white fur also appear on his wrists, the end of his quills and on his chest. Likewise, his ears become more curved.

For attire, Sonic loses his white gloves, exposing his hands, and his socks becomes slightly frilled in the back. The white stripe on his shoes is replaced with grey metal that has three spikes on the surface, and his soles are now covered with small metal spikes.


Sonic was transformed into this form for the first time when Dr. Eggman used a machine to painfully extract the power of the Chaos Emeralds from Super Sonic, with which Eggman would fire a specialized laser weapon at the planet, releasing and awakening the creature known as Dark Gaia from the core of the planet. In the process, due to his close proximity to the Chaos Emeralds, some of Dark Gaia's energy infested Sonic's body, causing his transformation. Sonic only transforms at night because that is the only time of day when Dark Gaia can move about and affect people. When transforming into the Werehog (or transforming back to normal), a light and a cloud of purple smoke envelops him.

Sonic the Werehog features a different gameplay than Sonic's normal form. He attacks with his arms and fists, which can stretch out and punch his foes. In nighttime stages, Sonic loses his speed and must fight through swarms of enemies with his new fists. Rather than using a counted number of rings, Sonic uses a health bar, where collecting rings refills the bar. Aside from the usual ability of Sonic being able to race down ramps throughout the levels, in Werehog form you must get across gaps in a tightrope walking fashion.

Sonic retains most of his normal abilities and personality in this form as well as the ability to speak, though with more of a growl than normal. It appears, however, that Sonic gains some minor bestial behavior while in this form, as he howls like a real werewolf at the start of a night stage, during the Dark Gaia Phoenix boss fight, or upon getting an A-rank or S-rank. He can also run on all fours like a real wolf and fight in a more ferocious way than his normal self. Therefore, it can basically just be considered a darker, more feral form of Sonic rather than as a split-personality monster like other interpretations of werewolves. Despite this, however, Sonic the Werehog still has Sonic the Hedgehog's good heart. This is primarily due to his will, which is too strong for Dark Gaia to affect in any way.

Before the final showdown with Dark Gaia, Dark Gaia re-absorbed its remaining power that Sonic had incidentally taken at the start of the game, stripping Sonic of his Werehog form for good.

Powers and abilities

Physical Abilities

Due to his transformation giving him increased muscular density,[3] Sonic gains a noticeable increase in physical strength, allowing him to open sealed doors and entrances, effortlessly pick up, throw and swing larger enemies and objects, destroy metal vaults with one hit and even topple creatures several times his size, such as the Titan and the Dark Gaia Phoenix.

In this form, Sonic is able to stretch his arms over long distances in an instant. It is unknown how far he can stretch his arms, however. Sonic mainly uses this ability in combat, allowing him to increase his attack range, grab enemies from long distances, build momentum for his attacks and create various forms of combat moves with the energy of Dark Gaia. He can even enlarge his arms and hands to increase the power and range of his attacks even further. Besides combat, Sonic can also use this ability to travel around, such as grabbing onto ridges, stretching his arm out to the nearest pole, swing over there, then stretch out to the next pole, etc.

As a Werehog, Sonic loses his trademark speed, though he is still faster then the average human. He is, however, able to run faster by dashing on all fours, making able to run past enemies or launch quick strikes and assaults. Despite his decrease in speed, however, he still retains his normal lightning fast reflexes and agility.

In this form Sonic is also shown having the ability to use a form of dark energy, possibly due to Dark Gaia being the source of Sonic's Werehog form, which he applies in hand-to-hand combat, or uses to charge up his attacks. He can also put up a powerful energy shield when guarding, and can even pick up the Dark Gaia Force which is left behind by Dark Gaia's Minions when they are defeated. By harnessing Dark Gaia's energies Sonic can enter his Unleashed Mode, a temporary enhanced state that increases his strength, speed and durability.

Techniques and Moves

Sonic the Werehog uses a type of feral hand-to-hand combat to fight his enemies. Basically, when using his fists, Sonic can deal greater damage, but only in a focused area and when using his claws, he can attack several opponents at once, but the damage will be much less.


In this form, Sonic is slower compared to his normal form, which makes him less able to outrun his foes and forces him to adapt a new fighting style. Sonic is also unable to control this transformation, since it automatically activates and ends according to the sun. The Werehog also often fails when trying to communicate with humans, since people usually are afraid of him because of his appearance, and therefore he cannot be very social. This takes a toll on Sonic, making him feel depressed and somewhat unable to face those he knows, as seen when Amy does not recognize him while he was a Werehog. Sonic also gets a more ill temper in this form, as seen in Night of the Werehog.

Werehog Archie Profile

Sonic the Werehog, from Sonic the Hedgehog #264.

Sonic the Werehog has also appeared in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. His first, albeit non-canon, appearance was in Sonic the Hedgehog #193, during the brief Sonic Unleashed adaptation which took place in the "In Another Time, In Another Place" reality.

Sonic the Werehog's first "true" appearance was in Sonic the Hedgehog #264, shortly after Sonic the Hedgehog came into contact and breathed a whiff of the concentrated essence of Dark Gaia. Each time under extreme stress following that, Sonic began to transform into the Werehog, but was caught off-guard the initial times, thus resulting in a failed-transformation. However, Sonic finally transformed into the Werehog when his friends and himself were electrocuted by Thunderbolt and her regional Egg Army.

  • Sonic's gloves were torn apart during the first transformation. Because of this, Sonic the Werehog is one of the few non-robotic characters to not wear gloves. Oddly, when he turns back into normal Sonic, his gloves magically repair themselves. In the 360/PS3 version of Sonic Unleashed, Chip will even acknowledge this if the player feeds him enough food by asking, "Where do you put your gloves at night?"
  • Sonic the Werehog is based on the famous mythical creature the Werewolf.
    • The term "Werehog" is derived from the words "werewolf" and "hedgehog." However, this is a misnomer. The word "Were", as used in the term "Werewolf", derives from the Old English "wer" which is a Latin word meaning "man", making the term literally "Man-wolf", a man who became a wolf. Literally, this means the term "Werehog" means "Man-hog" which is an incorrect referred to Sonic being a man that becomes a hog.
  • Sonic's ability to stretch and extend his arms in this form is a trait that several of Dark Gaia's Minions possess, especially the Nightmare variant. This might be due to Dark Gaia's energy being the source of both Sonic the Werehog's and Dark Gaia's Minions' powers.
    • Additionally, the Nightmares are shown to guard like the Werehog, as well as execute the Wild Whirl.
  • Sonic the Werehog is the second of Sonic's transformations to have a profile on Sonic Channel, the first one being Super Sonic.
  • In the 360/PS3 version of Sonic Unleashed, if a player would press the jump button just as he/she grabs a ledge, the Werehog would perform a spin jump similar to Sonic's.
  • Sonic the Werehog is not the first character created by Sega to have elastic/stretchy arms: Ristar, another character conceived around the time of Sonic the Hedgehog, was the first in his 1996 debut Ristar the Shooting Star, along with Chaos from Sonic Adventure.
  • In 2009 a Sonic costume pack for Little Big Planet was released with a Werehog costume along with the Sonic, Tails, Knuckles, and Eggman costumes.
  • The Werehog bears some resemblance to Darkspine Sonic, as both of them are more violent than Sonic in his usual form and use punches and kicks rather than energy and spinning attacks. Both of them are also powered by some kind of dark energy. In the Werehog's case, Dark Gaia energy powers him; and in Darkspine Sonic's, the World Rings of Hatred, Rage and Sadness, which are negative feelings.
    • Darkspine Sonic and Werehog Sonic are also the only forms were Sonic isn't wearing gloves
  • In the PS3/Xbox 360 versions, Sonic the Werehog's Skill, Aerial Piledriver, looks similar to Zangief's signature move Spinning Piledriver from Street Fighter.
    • In addition to this, there is another move known as the Sho-Hog-Ken, a reference to Street Fighter's famous Shoryuken uppercut.
  • Most of Sonic's stretching punch mannerisms are similar to Monkey D. Luffy's from the manga One Piece.
  • Sonic fought the Egg Dragoon as the Werehog at night. But moments later, when Dark Gaia becomes Perfect Dark Gaia, Amy states, "It was broad daylight a minute ago!", implying that it had been day for several hours. Amy was in Shamar, which is east of Eggmanland on the map screen, so it was at least sunrise in Eggmanland. If this is so, Sonic probably should not have fought the Egg Dragoon at night.
    • Granted, he was far underground, away from the sun, and near a large amount of Dark Gaia energy.
  • The Werehog is very similar to Dark Jak from Jak II: Renegade as they are both powered by dark forces (Dark Gaia/Dark Eco) and both can have upgrades to expand their attacks.
