Fury. Billy might pound him a bit at first, but look at the graveyard that Cpt. Britain ended up in when he was fleeing the Fury. One of the graves said "Miracleman."

The Fury was a bad ass. He'd be able to take down a ton heroes/villains. Probably not all at once, but if he catches them solo, most of them are going down.

The original Fury from the Captain Britain strip, the one Jimmy J made is uber, uber, uber - he is what Nimrod would like to be - He killed Miracleman 😕 and as the caption said at the time "thats impossible". He killed Captain Britain too (his unstoppable).
