Shadow the Hedgehog (Sonic X)

Shadow, as seen in an episode of the anime, has white rings as a mistake instead of his gold ones in the games. Episodes 33 of 38 are based on Sonic Adventure 2: Battle, with quite a few differences from the game. For one, it was Chris Thorndyke who reminded Shadow of his true promise from Maria, not Amy Rose. Afterwards, he makes a short appearances in flashbacks, but he makes his true return in Episode 60, "the Return of Shadow".

In Season 2, Shadoe had no clear memory of his mysterious past, although in one episode, he seems to have an image of Maria in his mind. However, he cannot seem to work out who she really was. In that same episode, Dr. Eggman visits people of a planet the Metarex are warring with, including one orange-haired female teenager by the name of Molly. Shadow and Rouge meet her, and at the end of the French/Japanese version of the episode, Molly was killed by the Metarex. Shadow erects a makeshirt grave for her, and Rouge notes that she was similar to Maria. In the English dub, Molly is seen flying off into the sky and insteaf of a grave, Shadow says that he will miss her and he is worried about her being all alone out in space.

In Sonic X as in other games, Shadow is portrayed as being very powerful. In an attempt to kill Cosmo, he injured Sonic, Knuckles, Chris and Tails. His destructive power is also severely increased when he takes off his limiter rings as seen in one episode where he takes them off, subsequently single-handedly destroying an entire Metarex fleet.
