[@Cmmelody]: Shino looks okay, I'd say (though I think it's "breeding", not "bleeding"... Right?) Only concern might be the flesh-eating bug (not because of it's strength per se but that's part of it), but other than that I'd give him the seal of approval.

Edit: The problem, to be specific, is the question of how often/easily they can be deployed and utilized. Chomping through someone from the inside out is a brutal affair, obviously, but it's a problem if you start using it too liberally (which I assume you wouldn't necessarily be inclined to do for narrative's sake?) but still.
