The one known as Blob is a huge man. He is a mutant with great strength and a great bulk, which renders him as an immovable force when attacked. He is a member of the Brotherhood of Evil Mutants, a group of mutants bent on world domination.
Shatterstar clashed with him in X-Force #9, when the Brotherhood of Evil Mutants and Sauron clashed with X-Force. After taking down Warpath, Shatterstar and Siryn paired up to face him. Shatterstar sliced him, assumably finding a weak spot. But the Blob ended up jumping off the cliff before he had a chance to be defeated by Shatterstar.
