Basically a genetic hybrid of Peter Parker and Venom, sharing all the Venom's abilities and Peter's IQ (and some of The Other's powers)+ ability to create clones out of dead corpses.
A friend of mine says that he's really uber (but then he attributes to him some of Venom's fanboy powers and makes a big deal out of Peter\symbiote mix on genetic level).
I'm well aware that it can be fanboy BS (the guy attributed to Poison many exotic "silver-agesque" Venom's powers such as travelling the electric cable etc).
