Gehenna

She is the girlfriend of Firestorm (aka Jason Rusch), who has the ability to teleport and some limited telepathic abilities.
Gehenna Hewitt (pronounced juh-HEHN-uh) is a female, Asian-American hero in the supporting cast of Firestorm. She appears to be an older teen, but she is actually six or seven years old; this is somewhat demonstrated in her maturity, but she is for the most part accepted as a near-adult. She can teleport over small distances, and has a psychic connection with members of the Firestorm matrix, most notably Jason Rusch and Martin Stein.
