Erika's Tangela was sent out first during her Gym battle with Ash and it managed to defeat Ash's Bulbasaur with a
Stun Spore, which paralyzed it. Realizing that his Grass on Grass battle technique wasn't working against
Erika,
Ash Ketchum sent out his Charmander.
Erika then told
Ash Ketchum she'd give him a Paralyze Heal after the battle which showed her loving and compassionate side.
Erika's Tangela was recalled as
Erika didn't like the matchup and
Erika's Weepinbell was sent out second to counter
Ash's Charmander instead.
