Jimmy O'Donnell's stepfather was killed by Scorpion, a masked terrorist, member of the Irish Republican Army (IRA).
He himself was saved by sheer luck, when the criminal mistook the howl of the wind for the scream of a Banshee (a spirit from Irish mythology that serves as a harbinger of death) and escaped from the scene of the crime. Jimmy chased the Scorpion across the Atlantic Ocean to the United States. Using Scorpion's superstition to his advantage, Jimmy disguised himself as a Banshee, cornering the terrorist and defeating him.
While preparing to return to Ireland, Jimmy was contacted by Professor Supermind, who offered him a position in the second Atomic Squad.
POWERS & WEAPONS
Banshee had no superpowers, just his wits, a good right hook, and a pair of 45 AMT Hardballers. Later, the S-Machine would be used on Jimmy, turning him into an undead with the ability to extract information from deceased persons.
