A.C. O'Connor (Earth-616) VS AC-DC (Earth-616)

A.C. O'Connor (Earth-616)
A.C. "Ace" O'Connor was a reporter who got involved in the mysterious robot serial killer story surrounding Rom, Spaceknight. Unknown to the world at large, Rom was actually a heroic figure eliminating evil aliens called Dire Wraiths who had infiltrated the Earth using their shape-changing powers. To human eyes, Rom was killing random people with a ray gun, reducing them to ash. In fact, Rom's Neutralizer was banishing the Dire Wraiths to Limbo. [1] Ace was tipped off at first by the fact that all the "victims" of the robot killer in Clairton, West Virginia all shared the same birthdate. Ace's investigation brought her to the government program Project: Safeguard where she managed to capture Rom's Neutralizer in action on film. Upon developing her photos, she discovered the camera was able to capture what the human eye could not, showing an alien creature disappearing into Limbo instead of the "murder" of a human being.

AC-DC (Earth-616)
AC-DC were conjoined twins who were transformed by the reality-bending Jasper's Warp which engulfed the U.K. several years ago. Like other "Warpies", they were tracked down by government agency R.C.X. (the Resources Control Executive). Supposedly this was for their own safety, but in truth R.C.X. head Nigel Orpington-Smythe intended for them to be trained to become a superhuman army. They became part of the Cherubim, the first combat ready squad the agency trained. [1] Fearing for the safety of their charges if the plans of their superior Nigel Orpington-Smythe went ahead, several R.C.X. agents, led by Agents Michael and Gabriel, spirited the children away from the agency. They took them to Braddock Manor to enlist the aid of Captain Britain (Brian Braddock), figuring that he could lend them much needed protection, both physical and politically. However, the agents' decision to not fully inform the hero of their situation meant he was reluctant to help, and while they argued, the Cherubim were released from the van they were being transported in by Meggan, a young empathic meta-morph staying at the Manor. They fought Captain Britain and his allies, Betsy Braddock and Captain UK, but were swiftly overpowered.
