Victini

Victini is a Psychic/Fire-type Legendary Pokémon that first appeared in Pokémon Black and White. It is said to bring victory to whoever manages to befriend it, and it can provide a limitless amount of energy by touching others. In Super Smash Bros. for Nintendo 3DS / Wii U, it can be spawned from a Poké Ball or Master Ball and is one of the few Pokémon to not directly attack; it instead temporarily makes the summoner immune to knockback and gives them a boost to their attacks. Victini is an unlockable Pokémon; in Super Smash Bros. for Nintendo 3DS it is unlocked by playing 100-Man Smash for the first time, and in Super Smash Bros. for Wii U is is unlocked by clearing All-Star Mode for the first time.
