X-men : Children of the atom
I used to play this game for hours at my local arcade..
Few ppl played this game cause it was too fast, ppl now are used to Marvel Vs Capcom but Children of the Atom is the first game of the series that introduced that kinda art style & combat to the franchise..
The things you could do in that game were unseen at the time, i remember doing a combo on a kid with Cyclops and launching him into the air and finishing him with the super optic blast.
i don't even know how i did it, it was more luck than skill but regardless, it looked amazing.
