To me, Superboy is basically Young Justice's Mr. Fanservice. The way he's designed, his frequent shirtlessness, his constantly torn clothes and the fact that (at least for the first season) both his female teammates have major crushes on him (Artemis: "Mmmm, that boy...") make it obvious that one of the reasons he's there is to make the fangirls (and fanboys *ehem*) squee. So it should come as no surprise that another Kryptonian clone who looks almost exactly like him would be good beefcake material as well.
In "Agendas", Conner visits Cadmus Labs and unwittingly releases Match, another teenaged Superman clone, think Evil Conner with black eyes, more powers and less talking. This version of the characters seems to be an amalgam of Match & Superboy-Prime in the comics.
Conner's gets clothing damage too! Duh
