A little on Echidna (since she has more of a concrete history than most of my characters):

Born and raised in Nevada by Nigerian parents. Came out as transgender at 18, rejected by her parents and lived in a homeless shelter for 2 years. Lost use of her legs as a victim in a violent hate crime.

Desiring a way to walk again, joined underground fighting ring as a spectacle, to earn "easy" money. Finding success, she found herself stable enough to immigrate to Hell (see: HARD LOVE and RED HOT's "country") and live in an apartment while continuing her career as a disabled fighter. Some years later, she is able to afford amputation of her paralyzed legs and is fitted for prosthetics. She begins hormone replacement therapy.

At about age 26 she meets Starburst, another disabled fighter, who was on tour with [INTERNATIONAL WRESTLING FOUNDATION] at the time. Following a few years of friendship, then love, Echidna left underground fighting for professional wrestling. She is fitted for high preformance prothetics to match Starburst; they become partners. Currently, they live together as domestic partners in a condo in Southern California.
