Origin and History
Shrew (Marilyn Maycroft) was once a member of the mutant team Hell’s Belles. No longer wishing to be apart of the criminal circuit, she turned in her former allies to the police and in return received immunity for her role in the team.
The benefactor of the team, Cyber, ordered the Belles to attack Maycroft. The government-sponsored X-Factor were called in to protect her, but after being attacked Shrew took matters into her own hands and defeated Cyber herself.
Her current whereabouts and status after M-Day are presently unknown.
