Nothing is known about Whiplash, not even her real name. She is heavily into S&M and is married to a fellow fetishist who calls himself Blacklash. Both of their names are inspired by the original Whiplash/Blacklash Mark Scarlotti. At some point in the past, they met Andreas von Strucker and engaged in sexual activities with him.
Whiplash was created by Fabian Nicieza and Tom Grummett and first appeared in Thunderbolts #104.
Both Blacklash and Whiplash have not reappeared since, although Whiplash had a small cameo in the animated series Avengers: Earth's Mightiest Heroes and it's tie-in comic.
Major Story Arcs
Whiplash and Blacklash were captured or recruited by the Thunderbolts for being in violation of the Superhuman Registration Act (although it was never seen what exactly was "superhuman" about two leather-clad swingers). They were then trained alongside nearly a hundred other recruits by Baron Zemo and Andreas Strucker, now operating as Swordsman. They openly mocked Swordsman for his new found authoritative role with regards to their past encounter.
Powers and Abilities
Whiplash possesses no superhuman abilities, although she is armed with an electrified whip. Due to her sexual history, she likely can enduring pain and even revel in it, which could be used as an advantage in a fight.
Whiplash battles Black Panther and Hawkeye in the tie-in comic to Avengers: Earth's Mightiest Heroes.
