History
Metalhead had a similar history as his Earth-928 counterpart, until the time-traveling Brotherhood, posing as the original X-Men, created a divergent reality.[1]
When those past X-Men took over the evil megacorporation Alchemax, they used it to hunt and persecute Mutants for unknown reasons, including the X-Men of 2099.[1]
When Metalhead and the X-Men were trying to steal medicinals to help the people who lived in the so-called Outlands, they encountered another X-Men team from the past.[2]
Together, they fought Alchemax's private police, the Public Eye, as well as the Onslaught Sentinel, until the young X-Men traveled back in time again trying to return to their home reality.[1]
