Marnie's MorpekoDestined Rivals #137 Pokémon Card

Morpeko is a unique Dual-type Electric/Dark Pokémon introduced in Generation VIII, native to the Galar region. Known as the "Two-Sided Pokémon," Morpeko has two distinct forms: Full Belly Mode and Hangry Mode, which it cycles between due to its constant hunger. Its Pokédex entry notes that Morpeko eats seeds constantly to keep its hunger at bay, and if it goes hungry for too long, it grows wild and brutish, transitioning into its menacing Hangry Mode. This constant need for food drives much of its behavior and is a central theme in its depiction. In the games, it is famously associated with Marnie, one of the player’s rivals in Pokémon Sword and Shield, who always has a Morpeko by her side, showcasing its lively and sometimes mischievous personality. Morpeko's unique ability, Hunger Switch, allows it to change forms at the end of each turn, altering the type of its signature move, Aura Wheel, between Electric and Dark. Its design, resembling a small hamster or guinea pig, coupled with its dynamic personality, has made it a popular Pokémon among fans, symbolizing the struggles of hunger and the duality of nature.
