Giant Takada

Giant is a character of the day who appeared in The Punchy Pokémon.

Giant and his Hitmonlee were going to be competitors in the P1 Grand Prix. Team Rocket wanted to compete as well, so they could win the grand prize. Realizing they didn't have any Fighting-type Pokémon, they decided to steal one.

Unfortunately for Giant, his Hitmonlee was the first Pokémon the trio saw. Somehow, they snuck up on him, tied him up, stole his clothes, and locked him in a bathroom stall. Using his Hitmonlee, Team Rocket entered the tournament disguised as Giant, and managed to get to the finals. However, Ash caught on to their plan, when trying to beat them in the finals (with James poking his head out helping to spoil the disguise and have Ash and his friends deduce Team Rocket's involvement), and was able to defeat them with his Primeape. It is not known what happened to Giant after Team Rocket robbed him.
