Parody Of . . .Edit
The venom symbiote. It is unclear whether Pork Grind is the symbiote itself or whether it is a host of the symbiote (if it is a host, it would would probably be a pig host). Pork Grind's origin is also unclear, unlike the real venom symbiote.
Pork Grind has only appeared in What The--?! #20. He has not appeared since.
