Edmund's Seismitoad is a water/ground-type Pokémon owned by Edmund.
It was used in the Clupsplosion's 1st round to battle Stephan's Sawk. It easily dodged all of Sawk's attacks with Swift Swim and hit him once with Drain Punch. After being hit in the leg with Low Sweep, he used Brick Break, which hit hard, but Sawk recovered quickly. They exchanged Karate Chops and Brick Breaks, which left Edmund surprised that Seismitoad wasn't dodging. As Edmund notices the Low Sweep wound was slowing him down, Sawk powered up greatly with Bulk Up, then ended it with Close Combat. While it seemed that Seismitoad had taken virtually no damage, he collapses, leading to Edmund's elimination.
