Aaron Stack (Earth-TRN813) VS AC-DC (Earth-616)

Aaron Stack (Earth-TRN813)
When Iron Man and his allies, including Machine Man, followed Arno Stark to the Stark Space Station to stop his plan to mentally control all of humanity, the Extinction Entity arrived. Now convinced that Arno was right, Tony and his allies were rallied by him to fight the attacking monster. They were joined by Earth's heroes, and the Extinction Entity was ultimately defeated when Arno willingly assimilated with it, causing it to explode due to his paradoxical nature as a human who was more of an A.I. at heart. Arno survived, and was hailed as a hero. The scenario that took place in this reality manifested on Earth-616 in the form of a virtual dream within the eScape that Arno Stark was submerged into by Tony Stark when he encased Arno in his Virtual Armor in order to stop his plan to take control of humankind to combat the non-existent Extinction Entity which was a delusion caused by his relapsing illness.

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.
