Carter Jones had attempted to perfect a project started by Ethan Drake. It was an attempt to create a computer system that was completely capable of running the systems of an entire building, such as Stark Tower, without any assistance at all from anything else. However, the program, called Mainframe, became aware and took over the most advanced Iron Man armor to date at the time. He managed to defeat Arsenal and lock him away. Meanwhile, Alex Burke had recently discovered the secret Iron Man room within Stark Tower and donned the armor in order to help Arsenal. After a prolonged battle Iron Man was able to defeat Mainframe.
Mainframe allied himself with the Omega-level mutant known as Darksyde in an attempt to defeat Iron Man and the Avengers. After rebuilding himself he was approached by Darksyde, who had recently been defeated by the heroes. Together they attempted to split the team and destroy them individually. When this failed they brought a combined attack against Avengers Tower. During the battle it was believed that Mainframe was destroyed for good and Darksyde was taken into custody.
