When Mys-Tech tried to send all of Britain to Hell, Motormouth and Killpower fought at the Battle of London Bridge. She was also sucked into Hell but Killpower saved her and the other heroes, leaving himself trapped in the inferno. Harley was left depressed and quit MI:13, living instead on a council estate in London, where she was known for her work fighting the vampire invasion. She became the single mother to two children, Victoria and Albert (named after pubs), and every so often she'd be attacked by (and kill) a former Mys-Tech monster who thought she was an easy target. After one attack, she learned her children were psychic mutants who were removing her memories of the monsters to stop her being sad.
