History
Presumably, the past history of Frederick Dukes mirrors that of his Earth-616 counterpart.
At some point after the mutation of humanity, Blob was subsumed by the Hydra, a biological entity secretly engineered by Norman Osborn. Like all people who joined the Hydra, the biological creature attached to their body took full control of the host body, killing the host. The Hydra retained all the hosts' original memories and presumably their super-human abilities.[2]
While his body lived on as a part of the Hydra, Blob's soul presumably ended up in the Realm of the Dead, doomed to fight in an endless battle with other superhumans.[1]Attributes
Powers
When his body was possessed by the Hydra, it presumably retained all it's mutant abilities. If it gained any abilities, it presumably added regenerative powers, as the Hydra's have seemingly been killed when attacked by the Skull's army, but miraculously were restored and seem operating some three years later.
