In my imaginings (I haven't gone full-on net-writier with these, mostly because they're DBZ-wannabe amateur), but I always think of my right arm (and right eye) as a tool/weapon of various specifications (with the eye acting as a control augmentation for the more complicated incarnations). In the main concept, the arm and eye were both, er, dematerialized in an event that also left the other eye altered (such that it normally needs to stay closed), with the practically prototypical prostheses hurriedly whipped into functionality. Upgrades ensue?
FICTION ASIDE, real-world tyme, I'd like to think I could get into falchions (axe-like swords? Okay!), but maybe something like a smaller bladed weapon...or a stick.
Food? Right off I'd say some generic cheese (Colby, Colby Jack, string).
