Koga's Muk (gym2_ja-23) is a Stage 1 Grass-type Pokémon from the 闇からの挑戦 expansion. It has the Energy Drain ability that can discard an Energy from an attacking Pokémon if that attack damages Muk and a Sludge Whirlpool attack dealing 40 damage. Its design and stats position it as a disruption-leaning attacker that can punish opponents who target it.
