The name "Charem" serves as an alternate reference to the Pokémon Medicham within the Pokémon Mystery Dungeon special. Medicham operates as a secondary character and member of the villainous crew "Team Meanies," under Gengar's leadership. This group directly opposes the heroic Team Go-Getters.

Available sources provide no elaboration on Medicham's background, origins, or history preceding the special's events. Throughout the narrative, Medicham serves in a supporting antagonistic role, acting alongside teammates Gengar and Ekans. The character engages in conflicts with Team Go-Getters but exhibits no significant personal development, transformation, or revealed motivations during the special.

Beyond this special, no additional canonical appearances, backstories, or expanded character development exist for Medicham (or "Charem") in the searched materials. The character's role remains confined solely to this appearance as part of Team Meanies.
