Story

Before her death, Gwen Stacy and Norman Osborn had an affair, because Gwen felt sorry for Norman. Gwen became pregnant with twins: Gabriel and Sarah. Norman took the siblings to France where he raised them, claiming to be their uncle. They believed Peter Parker to be their real father, and were furious that he abandoned them and killed their mother. Gabriel, like his sister, was born with the goblin formula in his system. Due to this, they both age and heal much faster than a normal human; appearing as adults despite being around 9 years old. Gabriel is very much insane, possibly even more so than Norman Osborn.

Powers

He had increased strength, endurance, reflexes, and healing. He also used the same Halloween-themed gadgets as the other goblins, including: explosive pumpkin bombs, bat-shaped razorblades, and finger-mounted lasers.

Gabriel's also a very skilled martial artist.

Gabriel is also intellegent as his father was and psycotic and dangerous as him too.

Alternate Universes

MC-2 Later it was found out that Peter Parker, Spider-Man had a child with Mary Jane and had the exact powers of her father. She then fell under the name of Spider-Girl and Grey Goblin assumed her as his new enemy.
