I would love all of these. And I think most of them are shifters, though not all of them dragons. Khunnie is a jungle cat (leopard or panther maybe?) to me. Though he could pull of anything I wanted him to be.
Rain could totally be a dragon, as could T.O.P (and GD, of course).
The twins, again, could be any shifter, but sexy twin dragons? I'd be okay with it...
Suga might also be a cat, sleeps all day but ferocious when awake. With naturally sexy/graceful movements. And, though he's serious by nature, he doesn't take himself too seriously. (Sorry he's my main bias wrecker right now!)
