They are a Super-Skrull in training, created by author Brian K. Vaughan & artist Adrian Alphona, and debuted in Runaways vol. 2 #7. 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 Xavin's constant gender switching and unfamiliarity with Earth values and norms, though through proving their loyalty to the group, found acceptance.
