Marco Scarlotti

A villain who's been tangling with Marvel's finest since the Bronze Age, Marco Scarlotti made his debut in Iron Man #72 back in 1975, brought to life by a remarkable creative team that included George Tuska and Neal Adams. Over nearly five decades, he's kept dangerous company — sharing pages with Iron Man, Tony Stark, Captain America, and fellow rogues like Whiplash and Blacklash — popping up across titles from Iron Man to Captain America to Joe Fixit. He may not rack up the highest appearance count, but any character still turning up in 2023 from a 1975 Bronze Age debut has clearly carved out a lasting niche in the Marvel universe worth any serious collector's attention.
