Peter is a clone of his father. (same eye glasses prescription, "You look just like him", etc) Rhino will be one of many other products of cross species genetics (Scorpion, Vulture, etc). I don't this next thing will happen, but I think it would be cool: -Norman Osborn will use the cross-species genetics in order to prolong his life (cure his cancer or whatever), but will eventually do it too many times with several different animal genetics in an attempt to become powerful and indestructible, etc. -- The result of what he transforms himself into can only be described as a "Goblin". -Venom will be the next thing once this genetics storyline wraps up.
