Reshiram appears in Super Smash Bros. for 3DS, as a stage Pokémon and a hazard. It appears on the Unova Pokémon League stage.
By setting its torch-like tail ablaze, this Pokemon can heat the atmosphere and change the weather. In fact, legend has it that Reshiram's flames are capable of incinerating the world itself, so perhaps the world's continued safety is a sign of its goodwill. Reshiram is said to help those who seek to build a world of truth.
