Wallace is a Contest Master and a Gym Leader.
battled against Ash Ketchum
in the middle of the street in Lilycove City during the time that Ash Ketchum
was participating in the Pokémon World Championships competition. Ash initially didn't know who he was but he reminded him of the contest that Dawn
participated in. He told Ash that he'd been following his
progress in the PWCS and he thought it was surely fate that they met and suggested a battle. Ash was in a hurry to see the Lilycove City Pokémon Contest that Chloe Cerise
was participating in but once Wallace
said that he was on par with the Champion of the Houen region, Steven Stone
, Ash couldn't refuse to battle! Most of the battle was not shown but Wallace
was defeated and he gave Ash Ketchum
a Rain Badge.
