Pokémon Stadium is a bootleg turn-based fighting game for the SNES. It is an unlicensed port of the Nintendo 64 game of the same name, featuring the same roster of Pokémon and a somewhat similar battle system. Unlike the original, this game features many different gameplay mechanics that don't appear to be from any Pokémon game, the most notable one being the addition of an evasion mechanic where the player can evade moves with a timed button press.
In this run, MarbleousDave chooses the Charizard known as "Lizad" and beats down all the competition, up to and including Pikachu, in record time.
