Ash's Totodile

Ash's Totodile was captured by Ash using his Lure Ball. Since Misty also wanted it, they decided to battle in order to determine who's it was. Ash won the battle.

Totodile has a jolly and playful personality and really likes to dance. It has even been known to use this dancing tactic to help win battles, it has also proven to be a really strong Pokémon in battles. Despite this, Ash left it at Professor Oak's lab as he decided to make a fresh start when he left for Hoenn.

Totodile reappeared in An Old Family Blend, where it had gone missing from its Poké Ball, like Ash's other Pokémon. Totodile was found dancing in the fountain, where it bit Ash's head after Corphish tackled Ash.
