Heh!..
Everytime I see Prometheus, I can't help but smile at that moment when he announced to Captain America that he'd downloaded the fighting skills of Batman...Stating, "Which should be more than enough to take down you.."
Which only results in Steve just giving him a subtle 'Oh really' look, before beating the living daylights out of him. :)
Never. Gets. Old!
..Even with the ret-con that now suggests that it was an inferior Prometheus..(Although I suppose Krona could have pulled out the original from the time line..)
