See: Carnivore and Farallah.
The Fearsome Fist of Farallah was created because of a wager that took place one thousand years ago by the Octessence, eight mighty beings. They each put their power into an item and decided that the first mortal to come into physical contact with each being's respective item would become an Exemplar, possessing the power of the being who created the item they interacted with.
One Exemplar was Andreas Zorba, the one who activated the Fearsome Fist's power. He worked with the other Exemplars to fight against Juggernaut who had betrayed the will of the Octessence. But thanks to Captain America, who used Bedlam, Farallah's influence was driven out of Andreas but the Fist still gave him its power.
Its current whereabouts are unknown.
It gave Andreas the abilities of superhuman speed, coordination, flight and combat skills.
