A version mascot is a Pokémon that appears on the boxart—and often label—of one of the Pokémon games in the core series.
Early on, the first two version mascots in a generation shared more of a relation with each other than with the third; however, in the Hoenn and Sinnoh trilogies, all three had a significant relationship between them. Since Generation IV, if the version mascot of the game being played is defeated, it may be battled again later.
Since Generation II, all version mascots have been Legendary Pokémon, barring Gen I's remakes.
