Sonic the Hedgehog (Modern)
Shadow the Hedgehog
Shadow the Hedgehog is the second rival in Sonic Generations, fought in a race reminiscent of the original battle, Final Rush, and Final Chase from Sonic Adventure 2 and also partially resembles Space Gadget from Shadow the Hedgehog.
The battle is fought in a looped circuit. Sonic and Shadow must race each other to gain Energy Cores. However, because Shadow can perform a Chaos Boost move, Sonic will have to keep performing boost as well in order to keep ahead of Shadow; boost energy can be obtained by collecting rings, jumping off trick ramps, or destroying blue tinted meteors. When Sonic and Shadow collide with their boost, they will ricochet off each other sometimes sending either off to the side, where it's harder to collect the Energy Core. If Sonic falls too far behind Shadow, Shadow will fire several Chaos Spears directly at Sonic (getting hit by them with no rings will still result as Sonic losing a life as normal). Sonic can also attack Shadow via Homing Attack or Boosting into him while he's not boosting to knock off his rings, but ultimately, both will want to finish each other off using their special attack. Once either Sonic or Shadow gain two Energy Cores, they will immediately perform a special attack. If Shadow gains two Energy Cores first, he will launch several Chaos Spears onto the ground that Sonic will have to avoid using quick step, before launching a large Chaos Spear at Sonic applying Chaos Control to try to throw off Sonic's timing. If Sonic gains two Energy Cores first, his boost now lets him smash into meteors that will fly into Shadow, slowing him down. If Sonic can catch up to Shadow, he can ram into Shadow eating away at his rings. The battle ends when either character loses all their rings whilst the other is performing their special attack.
In hard mode, both characters have to get three Energy Cores in order to perform their special attacks. Shadow also seems to be much faster and more proficient in pursuing Energy Cores, taking the higher routes more often. The blue meteors and almost every trick ramp that give boost energy are also absent, making it harder to maintain boost.
- The main stage theme is a remix of "For True Story" from Sonic Adventure 2. During the stage, if Sonic gains two Energy Cores, the music switches to Live and Learn. If Shadow gains two Energy Cores, the music switches to the Crush 40 version of All Hail Shadow. After about 40 seconds, the music returns to For True Story.
- When Sonic powers up, his boost changes color from cyan to purple.
- It should be noted that when Sonic powers up, the boost is done automatically, meaning that the player just has to focus on quick-stepping to hit the meteors.
- The opening cutscene for the fight is nearly identical to the intro to Sonic Adventure 2 Battle.
- This version of the fight takes place on a looping arena with many interactive objects such as grind rails and meteorites, which differs greatly from the original, which took place in a never-ending straight track, with no rails and meteorites as merely destructible objects.
- Perhaps the largest change in the structure of the course is the fact that the platforms do not disintegrate as Sonic runs on them, as they did in the original.
- This is the only Rival Battle where the Rival is governed by rings rather than a set amount of hits emphasizing the race aspect to defeat one another rather than a straight out battle.
- Shadow is the only rival boss where he does not skid across the road after he takes damage.
- This is the only boss that never switches to 2D gameplay.
- Before the race, it's shown that Shadow guards the fourth Chaos Emerald. Although this might just be coincidence, this is possibly due to a famous line from Shadow the Hedgehog, where Shadow says: "Where's that DAMN fourth Chaos Emerald?"
- This is the only rival boss that does not take place in the future.
- The music played in the Hub world is a short, instrumental remix of Throw It All Away, Shadow's main theme in Sonic Adventure 2.
- If one manages to leave the area where Shadow unleashes his special move, his AI will have problems. He'd knock into walls and reach ridiculous speeds that even the Sonic Boost can't keep up with. If the player stays at the area with the Rainbow Ramp long enough, he'll unleash a Chaos Spear that will mute the whole game. The sound would be restored after reloading the game. Also, Power Cores will not appear on the stage game so whether the player activates this glitch for the mentioned issues above for amusement or not, the player will need to restart or exit the stage.
- If you get the second energy core as you are doing tricks, the models for Shadow and the asteroids will disappear for the rest of the fight.
- If Sonic, from the area where Shadow uses his power-up, runs a long distance until the path ends in a pit where Sonic falls to his death and loses a life.
