A mutant originally depicted as a morbidly obese circus freak, the Blob claims to be immovable when he so desires.

He is detected and contacted by Charles Xavier via Cyclops, who sees his performance and tells him that he (Dukes) is a mutant, and asks him to join the X-Men.

Xavier telepathically contacts Marvel Girl and tells her to remove her blindfold using her telekinesis, then levitate a knife from a performer's tent to cut through her bonds, after which she frees the other members.

The psychic entity Onslaught later recruits Blob, vastly upgrading his powers and abilities (in his powered-up state, his mutation becomes virtually identical to that of Phat).

Months later, a powered-down Dukes joins the new Brotherhood led once again by Mystique, alongside Toad, Sabretooth, and the daughter of the original Mastermind.

Due to the Scarlet Witch's depowering of 90% of Earth's mutants, the Blob is one of the thousands to lose their power, though his epidermis does not shrink to compensate for his loss of mass, leaving him with huge folds of loose skin.

The depressed Blob attempts to commit suicide, but his skin folds prevent him from cutting through to any major blood vessels on his throat or wrists.

Now known as Freddie Dukes, he has become a weight-loss guru in Japan, and is to star in an upcoming movie filmed in San Francisco made by Kingo Sunen.

[33] In the miniseries "Magneto: Not a Hero", Joseph is resurrected under unknown circumstances and forms a new Brotherhood of Mutants with Astra and mutated deformed versions of Blob, Mastermind, Quicksilver, Scarlet Witch, and Toad.

[34] In Uncanny X-Men #16, Fred Dukes is working with Mystique in Genosha and is once again shown as heavily obese and appears to have his powers restored.

[volume & issue needed] He could also alter his personal mono-directional gravity field beneath himself to make himself virtually immovable as long as he was in contact with the ground, although an incredible force can uproot him, along with a chunk of whatever he is standing on.

The only beings on record to have been able to move the Blob against his wishes are the Hulk,[16] Juggernaut,[citation needed] and Strong Guy (powered-up near his limit by absorbing kinetic energy),[37] although Colossus has managed to lift Dukes by digging underground and raising the piece of earth Dukes stands on, stating this as an exception to his immovability.

[38] Despite his appearance, the Blob's speed and agility are those of a fairly athletic male of normal stature, a fact which frequently catches his opponents by surprise.

[volume & issue needed] The Blob is vulnerable to attacks directed at his face, as his eyes, nose, mouth, and ears do not have the same protection as the rest of his body.

Dukes is also susceptible to psionic attacks and psychic manipulation, and he can be incapacitated by sensory assaults; for example, Banshee was able to render Blob unconscious solely through the use of his sonic scream.

On another occasion, Sleepwalker defeated the Blob by using warp beams to wrap a steel girder around the villain, crushing his blubber and causing him great physical pain.

While he is all but invulnerable to direct kinetic attacks, such as punches, kicks or gunshots, he is susceptible to concussions and other harm resulting from sufficiently powerful impacts, as Daredevil knocked him out by luring him underneath a massive bell and then having it dropped on him with the aid of a young female mutant.

His pseudo freedom was fleeting because moments later the head of the pens, Havok's older brother Cyclops, showed up to deliver a searing optic blast that would put him back in his place.

It appears that McCoy or Sinister himself had his powers altered in a manner that allowed Blob to project his gravitational field outward.

Kurt seemingly succeeds in his goal of revenge by teleporting a live shark into Fredrick's stomach during a fight with him, causing him to be devoured from within.

[51] Deadpool's search for Cable across alternate timelines forces an encounter with the Blob of "an age of Apocalypse" (not to be confused with the X-Men story arc of the same name).

[52] Put in an internment camp after Bolivar Trask's rise to power in the House of M reality, he was freed in Magneto's first major raid on US soil.

[54] In the Marvel Noir reality, Eric Magnus is Chief of Detectives and Fred appears as a member of his Brotherhood, a cabal of bent policemen.

He is alive when first encountered, but being pursued by several zombie versions of Marvel characters, including Pyro, Black Cat, Iron Fist, Toad and Rhino.

[57] In the pages of Uncanny Avengers, the Blob is an enforcer on the alternate universe (Earth-13133) when the Apocalypse Twins skew the time lines and create a mutant utopia called "Planet X".

[58] The Ultimate Universe version of Blob, real name Franklin Dukes,[59] is a member of the Brotherhood of Mutant Supremacy.

One such incident sees the Blob pretend to be a female model/physicist named Naomi who cyber-seduces the X-Man Beast—leading to the discovery of Magneto's survival and to the Ultimate War saga.

Teddy is in high school and has his father's same bulky appearance and similar abilities, as he was shot at point blank range and merely said "It tickles".
