Origin

On an alternate Earth (Earth-238), Mad Jim Jaspers created the Fury to kill all superhumans save himself. Jaspers was a being capable of altering reality, so though The Fury is mechanical, it isn't like any other machine or cyborg. Fury did what it was programmed and killed every superhero in its world except for Captain UK, who escaped Otherworld. Mad Jim Jaspers was found to be too dangerous so the temporal overseer destroyed Earth-238, but The Fury escaped to Earth-616 where it continued its mission to kill superhumans. Fury also found this reality's Mad Jim Jaspers and decided that since he wasn't the original Jaspers, it must kill him. They battled. Jim could alter reality, but The Fury could adapt itself in order to counter anything Jim did. So, they were at a stalemate until The Fury transported them both to a universe where reality itself no longer existed. Mad Jim had no reality to manipulate so the Fury killed him. When it returned, Captain UK attacked it while it was still weak, forcing it into hiding while it could heal the damage.

The Fury came back in Uncanny X-Men (#444) and fought the X-Men. On the first go-round it broke Cannonball's leg, knocked Rachel into the sky, knocked out Bishop and came close to killing each of them indiviually. He then used Sage's glasses to take over her mind. It was only defeated when Rachel Grey created a black hole inside of it, with the help of Storm, Sage and Bishop, sucking it in and teleporting it away, but not destroying it.

Since then, The Fury has made one appearance. In Uncanny X-Men #462, Jaspers was resurrected in Other-world and looked like he had parts of The Fury merged with him. Thene he created an army of furies, slaughtering many of the captain Britain corps.

Powers

The Fury is capable of adapting itself in any way in order to complete its assignment to kill superhumans. Its powers exist as long as he needs them. Since it can give itself any power it needs, no list of its powers would ever be complete. It is able to see superhumans' weaknesses and adapts itself accordingly, to help kill them all. It can find a way to kill anything and survive in any situation. From every attack used against it The Fury learns to neutralize it.

The Fury is also virtually impossible to destroy. If even the smallest part of it remains, it can rebuild itself completely by using surrounding materials.

The Fury has great analytical and tracking devices. It can even track its targets between dimensions; so it is almost impossible to escape it.

The Fury would never stop until it has accomplished its goal to exterminate all super-humans.
