- “I don't regret the things I do. I'm proud of what I am. I'm proud of what I've done for my country. But if you think you can take me, step up to Fred J. Dukes, you better run. 'Cause if I were to catch up, I might teach ya some manners.”
Blob (born Fredrick J. "Fred" Dukes) is a mutant who has super strength and incredible durability.
X-Men Origins: Wolverine Prologue
During the Vietnam War in mid-late 1973, Fred Dukes was a member of Team X under Major William Stryker's command. Fred demonstrated his strength by blowing up a tank simply by plugging his fist inside the tank's chamber, causing its blast to backfire.
After the team disbanded, Fred became very obese (having developed an eating disorder), and John Wraith was trying to whip him back into shape (Unfortunately, Fred usually knocked out his opponents by just bouncing them with his huge stomach). Fred later angrily challenged Logan to a boxing match between them because he thought Logan referred to him as "Blob" to Wraith - even though the spoken word was "Bub". Wolverine won by striking him on the head multiple times and later wanted answers about the Island. Fred reveals that Victor and Stryker are working together, capturing mutants and experimenting on them, having allegedly learned the information from Agent Zero. Dukes then informs Logan that he does not know the location of Stryker's base, but says that there is only one person who escaped, a mutant and Cajun street hustler named Remy LeBeau, who goes by the name "Gambit". Wolverine and Wraith later went to find Gambit after Dukes gave Wolverine the information he wanted. Later when Victor was trying to kill Wraith, Wraith said that Victors black coat doesn't scare him and Victor then said that it worked well on Dukes, implying that he killed him.
Due to Wolverine traveling back in time to January 1973, and preventing Bolivar Trask from being assassinated by Mystique, and changing the significant events after that point, Team X was never formed. Thus, he along with other members of Team X, were never hunted and killed by Victor Creed.
Blob was among those that Angel defeated in a fight club. It is unknown whether or not Angel killed or greviously injured him, as Blob was bleeding from the large cut on the back of his head, which he recieved from battling Angel. He was carried out of the arena on a stretcher.
Powers & Abilities
- Superhuman Durability - Blob's body possesses a high degree of resistance to injury, practically invulnerable to nearly all forms of physical harm. He is able to absorb the impact of strong blows unfazed. He made a cannon explode by putting a hand inside of it while it was shooting, without receiving any injury to himself. Overall, his resilience appears to have its own gravitational pull. This allows him to be almost completely immovable unless it is by his own free will or if his opponent's strength rivals his own.
- Superhuman Strength - Blob has a high degree of physical strength. He is able to throw a man in the air with no efforts, and he's strong enough to punch Wolverine's adamantium skeleton without injuring his hands.
- Boxing - Due to his obesity, John Wraith attempts to train Blob through Boxercise to lower his weight.

- In a deleted scene, Victor is seen getting a call from Stryker. He tells Stryker that he knows where Wolverine and Wraith are going because he had Dukes tell him. He hangs up the phone after and starts moving towards Dukes, implying that he is about to torture and kill him.
