In the "Pokémon Adventures" manga, many Psyduck have appeared in the manga owned by other trainers. In the Red, Green & Blue chapter, an undead Psyduck, that had been brought back to life by a Koga's Gastly, appeared in the Pokémon Tower. It first appeared to Red like a normal Psyduck, until it attempted an assault on him: its eyeballs suddenly sunk into its eye sockets and some skin fell off, revealing its bones. Since it was just a mindless undead, it was easily destroyed by Red's Bulbasaur.
