Champion

A Pokémon League Champion, usually refers to a Trainer who has completed a Pokémon League by collecting all the necessary Badges, and either winning a regional Pokémon tournament or defeating the Elite Four and the previous Pokémon Champion (if there is one). The Champion usually resides in the Indigo Plateau with the Elite Four but some relinquish the position to pursue other adventures, train, or retire. This is the case with the current Kanto Champion, Red, who left his Champion duties to the current Johto and ex-Kanto Champion, Lance.

Lance

The current dragon master of Blackthorn City and Cousin of Clair the Blackthorn Gym Leader, The Player meets Lance at the Lake of Rage in Johto and assists him in defeating Team Rocket in their base in Mahogany Town. Though he is only the Johto Champion he was once the Kanto Champion as well and currently serves as the Kanto Champion in Red's place.
