160

Ash Ketchum challenges the Goldenrod City Gym Leader, Whitney, to win his next badge to compete in the Johto League. After Ash easily beats Whitney's Nidorina and Clefairy, Whitney sends out her third and final Pokémon, Miltank. Miltank defeats Ash's Cyndaquil and Totodile with its Rollout attack. Ash, in despair chooses Pikachu as his final Pokémon but despite their combined efforts and a strategy involving shocking Miltank while it's still wet from Totodile's Water Gun attack, Miltank's Rollout is just too strong and as a result, Pikachu soon faints, resulting in Whitney winning the battle.
