Leann was born in Wilmington, Delaware. She was a mutant with unraveled abilities and she used adamantium
wires which were connected to her gloves as whips.. She was part of Critical Mass' Band of Baddies. The Baddies forced the mutant daughter to knock out the Spider-Man
but they quickly recovered. The daughter than unleashed her powers, blew up the warehouse they were in, and defeated all of the Baddies.
She was later joined in Femme Fatales
, and she was hired by the Chameleon
to threaten an ambassador. Spider-Man intervened and saved the ambassador, making an enemy with the Femme Fatales. They then joined forces with the Scorpion
and the Tarantula
, but all of them were defeated by Spider-Man and the Black Cat
. The Femme Fatales later received an invitation to join Superia
and her organization of female criminals, the Femizons
. They accepted, and battled Captain America
and the Paladin
in the process.
After the group disbanded, Whiplash teamed up with Orka
and Killer Shrike
in a plot to take over the retired aircraft carrier, the U.S. Intrepid, planning to use it to extort money from the city of New York, or from the US Government. She and her allies were defeated by Heroes for Hire
. She was later seen in "Bar With No Name" attending the auction in which the Venom Symbiote was sold.
Whiplash was possibly de-powered after the events of M-Day
