Aaron Carpenter (Earth-616) VS AC-DC (Earth-616)

Aaron Carpenter (Earth-616)
Dr. Aaron Carpenter was the world's greatest living brain surgeon. He knew Bruce Banner from high school, whom he saw as an "insufferable geek." After Bruce Banner was shot in the head, Carpenter was contacted by the Ancient Order of the Shield,[1] disguised as S.H.I.E.L.D., the ones who secretly had Banner shot, and was brought in to operate on him. During the surgery, Carpenter was ordered to place a device capable of controlling the Hulk's transformations in Banner's brain. Aaron hesitated, and thought of killing Banner to prevent the agency from controlling Hulk, in order to save lives. However, Banner was awakened by the anesthetist, whose life had been saved by the Hulk decades ago, triggering his transformation into the Hulk. The agency released a gas in the operating room in order to eliminate the witnesses of their actions, but the Hulk managed to break a wall and allow the gas to scatter, saving the life of Carpenter and the other participants of the surgery.

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.
