History
The history of this incarnation of Adrian Toomes is most likely in large parts identical to that of his Earth-616 counterpart.
Obsessed with regaining his youth and original good looks, Adrian Toomes broke into the factory of Glamor Gal cosmetics; a company that in the process of trying to develop an age defying makeup had accidentally found a chemical that could actually reverse a bodies age. Spider-Man interfered and tried to capture him, but in the battle he ended up falling into the chemical himself and was de-aged to a child. Adrian was able to escape with a flask of the chemical, and used it on himself to become a young man again. He briefly retired from supervillainy to enjoy his newly regained youth, but found out the hard way that salt water undid the effects of the chemical.
After having been restored to his old age, Vulture rejoined the Sinister Six and teamed up with a Venom-possessed Katie Powers to capture Spider-Man. He was bested in a fight by Lightspeed.
