Shadow the Hedgehog (Sonic Generations)

Final Rush is the setting for a rival boss stage in Sonic Generations. It is where Shadow the Hedgehog is fought in a race/battle reminiscent of the original Final Rush and Final Chase from Sonic Adventure 2.

Gameplay
The battle is fought in a looped circuit. Sonic and Shadow must race each other the gain Energy Cores. However, because Shadow can perform boost, 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. Sonic can also attack Shadow via Homing Attack or Boosting into him while he's not 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.

Hard Mode
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 that give boost energy are also absent, making it harder to maintain boost.

Trivia

 * 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 switch 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.
 * The opening cutscene for the fight is nearly identical to the intro to Sonic Adventure 2.
 * 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, though he does when he's defeated.
 * This is the only boss that never switches to 2D gameplay.
