Blacklash

First Appearance: Tales of Suspense 97
The Story: Mark Scarlotti, although he's also been called Mark Scott AKA: Whiplash. He changed his codename in Iron Man 146 when he upgraded his arsenal to include a bullet-resistant mesh cloak, a concussive charge in his whip handle, and a number of other cute tricks. He also dyed the plume in his helmet green instead of orange. When in costume, Blacklash is pretty much a sadistic jerk that likes to bully other people. Out of costume, he's a manic depressive who wishes he had his costume on so he could bully other people. Formerly one of Stark's research heads, Scarlotti became en tangled with the Maggia. Accepting Maggia money for his research, he constructed a unique metallic whip that is stronger than most other metals with the probable exception of adamantium. Since Iron Man doesn't use adamantium in his armor, Blacklash has been able to give him some serious trouble over the years.
