The mutant Magneto soon seeks out the Blob to recruit him into his Brotherhood of Evil Mutants, restoring his memory through a jarring blow to the head. The Blob temporarily accepts the invitation, but leaves when it is revealed that Magneto has no real concern for the Blob's safety after he is hit by explosives which were launched at the X-Men. He goes back to the Circus. He teams up with Unus due to the alien Lucifer, who soon becomes his confidant. They disguise themselves as X-Men and commit crimes. The Blob also serves as a member of Factor Three. He briefly works as an operative for the Secret Empire, where he fights the Beast. With the reorganized Brotherhood, the Blob fights Professor X and the Defenders. He is reverted to infancy by Alpha the Ultimate Mutant. The Blob is later returned to adulthood, and fights the Champions of Los Angeles.
