Girida

Girida is the codename of a feared, strong mercenary who travels the multiverse. She barely has morals and will do anything she is hired to do if the pay is good enough, including murder. She wields powerful Pokémon that she stole from across the multiverse and breaks taboo by carrying more than six at once as she pleases. She wears an elaborate outfit that obscures her face, modelled after both the Legendary Pokémon Giratina and the leader of the ancient Sinnohan Pearl Clan Irida (hence her codename). She owns a powerful Red Chain she bought at a high price from the Multiversal Black Market, allowing her to subdue and wield almost any powerful Pokémon.

No one knows her true identity, and she's not even sure if she herself remembers. In truth, she's an evil version of Geeta from another universe, but she hasn't gone by that name in ages (she doesn't remember how long).
