What is "xavin"

Xavin is a fictional superhero in the Marvel Comics Runaways. They are a Super-Skrull in training, created by author Brian K. Vaughan & artist Adrian Alphona, and debuted in Runaways vol. 2 #7. Although Alphona was the series' artist at the time, artist Takeshi Miyazawa first drew the character on print.

Xavin had first appeared to the Runaways, taking on the form of a black male, but changed into a black female just for the sake of Karolina Dean, a lesbian whom she was to marry. Xavin is often seen as a male, simply to be "intimidating". Xavin, often called "Xav" for short, is known for their obtuse and warlike personality. They had originally found it hard to fit in with the runaways due in part to their constant gender switching and unfamiliarity with Earth values and norms, though through proving their loyalty to the group, found acceptance.They are the child of the Skrull Prince De'zean.
