Mouser

Intro blurb.

Prior to Steel Hearts
Her life prior to entering professional wrestling is mostly unknown. She is said to be from 'the land between the sea and the shore', a parallel world to ours. She has been stranded here with no way to return, and the gladiatorial realm of professional wrestling gives is the only touchstone she has for home.

At some point she met Sammy Cage. The world of southern professional wrestling could not be 'any more bizarre' and Sammy was strangely well equipped to handle a stranger from a strange place. The two would never get along, nor hate one another to develop a rivalry, but would develop a mutual respect for their combat abilities. Mouser does not entirely trust Sammy, but frequently relies on her for business measures beyond her understanding.

History
Once Iris had joined UYWU, she was handed the gimmick of a cat girl gladiator from another dimension. The original gimmick was a Roman gladiator that had been thrown forward in time, and was offered to a different performer. The original subject firmly rejected it with the threat of walking out on her contract. Because Iris wasn't white, the gimmick required minor tweaking, and in the hands of an unchecked creative department with bizarre kinks and mildly racist misconceptions, it became a cat girl.

Iris didn't have the sway to reject the gimmick and keep her job, she begrudgingly accepted the role forced onto her.
