|Real name||Frederick Dukes|
|First appearance||"X-Men #3"|
As a child, Fred was bullied because he was overweight. He eventually snapped and beat one of the bullies to death. He was brought to a juvenile hall where he stayed until he was seventeen, at which point he was still overweight, no matter how hard the guards made him excersize. He came to the realization that he was a mutant.
After turning nineteen Fred joined the circus to cash in on his super strength. At some point, Nathaniel Essex saw one of his shows and was intrigued. He offered Fred a way to be a god instead of a circus freak. He accepted almost immediately. He joined the Hellfire Club and became extremely dangerous.
Brotherhood of Mutants
After the X-Men stopped the Hellfire Club from starting World War 3, Magneto killed Mister Sinister and the remaining members of the Hellfire Club joined him in the Brotherhood of Mutants, including Blob.
