Mainframe is the name of three characters appearing in American comic books published by Marvel Comics.
Earth-691 version The Earth-691 version of Mainframe is a future counterpart of
Vision that is featured in the title
Guardians of the Galaxy. Mainframe is the chief operating system of an entire planet, and the guardian of the
shield of hero
Captain America. He soon joins the Guardians of the Galaxy spinoff, the
Galactic Guardians.
Earth-982 version The Earth-982 version of Mainframe appears when
Iron Man decided to retire from the hero business. Iron Man did not want to let his legacy end, designed an
android patterned after the Iron Man armor, and called this robotic warrior Mainframe. Mainframe was brought online when
Trolls attacked the young boy Kevin Masterson. Mainframe assembled all of the reserve
Avengers and fought to save Kevin. When the fight was over, Mainframe,
Stinger,
J2, and the new
Thunderstrike formed
A-Next, a new team of Avengers. Right away, Mainframe attempted to establish himself as team leader. He frequently encountered resistance from Stinger who did not know that Mainframe was a robot. But when Mainframe was terminally damaged, exposing his secret, Stinger was one of the first to volunteer to shrink inside to repair him. They later learned that whenever Mainframe was severely injured, he would upload his personality and memories into a replacement body assembled on an orbiting
satellite.
Earth-616 version The Earth-616 Mainframe is an android who is a member of the Guardsman Alpha Squad. He is killed in battle against the zombie Squadron Supreme from the
Marvel Zombies universe.
