Master Ball

The Master Ball is an item from the Pokémon franchise and a more effective variation of the Poké Ball. In the games, it is generally given to catch rare and Legendary Pokémon due to its catch rate of 256, allowing it to catch any wild Pokémon it is thrown at.

In the Super Smash Bros. series, the Master Ball appears in Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate. It is a variant of a Poké Ball, and usually only releases Legendary or Mythical Pokémon (including Zoroark, who does not fit into those categories). A Master Ball may occasionally release a Goldeen as a dud.
