despite looking like the worst kind of fan-fiction, this is an actual character from Web of Spider-Man # 90 (way back in 1992). Okay, so he was just an illusion powered by Mysterio, and very easily defeated by Spidey, but the image of this guy has stuck with me for what must now be 20 years!
He's made from a MU Galactus figure. His head was resculpted with Milliput and I added the individual fangs. His tongue is electrical wire covered in hot glue. There's also hot glue in the back of his mouth, coated in clear red, which allows the light-up feature to illuminate his mouth.
I swapped his hands out with those of the ML Icons Venom figure.
The Venom emblem is sculpted on, taking care to preserve access to the battery compartment at the back.
Hope you guys like him.
