Misty was once a young slip of a girl. But she's spent a lot of time in the gym packing on the muscle that a top Pokémon trainer needs to be competitive. Now she can deadlift 484 pounds!
Here she is protrayed by Zeek Kotwal, a model and (obviously) serious bodybuilder. He markets himself as an event presenter, public speaker, and (presumably) Pokémon trainer. You can see more images of him in costume on his Facebook page.
