Blob

Fred Dukes was a carnival sideshow performer whose mutant nature became apparent through his extraordinary girth and near-immovable body. Recruited by Professor X, he refused to join the X-Men and instead allied with Magneto's Brotherhood of Evil Mutants, beginning a long career as a supervillain.

Few villains in Marvel's Silver Age made an entrance quite like the Blob — crashing into The X-Men #3 in 1964, courtesy of Stan Lee and Jack Kirby, and never really leaving. Over 62 years and 265 catalog appearances, this immovable force has haunted the pages of The Uncanny X-Men, The X-Men, and X-Force, racking up 16 key-issue credits along the way. His team history is a fascinating tour through Marvel's mutant underworld — from the Brotherhood of Evil Mutants to Freedom Force, with stops alongside Wolverine, Cyclops, and Hank McCoy that have produced some genuinely memorable confrontations. If you want a character who embodies the raw, stubborn menace at the heart of the X-Men's earliest days and has kept pace with the mythology ever since, the Blob is exactly the kind of enduring presence a serious collection needs.
