History
Xargorr is a member of Moomba's race who arrived on Earth with her, but did not leave with the rest of her kind. Deciding to stay instead, Xargorr recruited more and more humans into service, making them forget their past lives while also erasing everyone else's memory of them. When she abducted the Thing and Mister Fantastic in such way, she finally got noticed by Susan Storm who always kept a low-level force field around her and thus was unaffected by the memory erasure.[1] Sue was able to defeat Xargorr by reflecting her full-strength psychic beam back at her with an invisible force field, making Xargorr erase her own memory.[2]
