Giovanni
Giovanni is another villain been hijacked from one of Chris's fandoms.
Giovanni is the main villain from Pokémon Red and Blue, and the leader of the criminal organization, Team Rocket within the games.
In Sonichu
Giovanni shows up during Sonichu #1. He is the adoptive father of Naitsirhc, Chris-chan's main rival, and along with Robotnik and Bill, Giovanni is responsible for the creation of Black Sonichu.
His role in the comic was very minor and his only goal was to help create Blake to capture Rosechu and defeat the original Sonichu. However, both Sonichu and Sonic go to rescue Rosechu, leading to a fight with Metal Sonichu. Note that Giovanni in the games is supposed to be a very powerful Ground-type Pokémon trainer. As Ground is the weakness of the Electric-type Sonichu, it can be seen as preposterous that he went out of his way to clone another Electric type to combat Sonichu.
Later, Giovanni appears in Sonichu #3 giving orders to Blake just before he begins his mission to steal the Legendary Master Sunstone. After the end of the comic Giovanni disappears from the series until Sonichu #7 in which he is part of the meeting of villains.
Giovanni reappears in Sonichu #9 as a player in the war on CWCville. He uses the Decepticlones to kidnap Rosechu in an attempt to blackmail Sonichu into instating Naitsirhc as the new Mayor of CWCville. His cunning scheme is foiled when he is knocked out by a basketball thrown by Bionic.
