Son of a bitch this would have been really fresh if it wasn't fake.

LOL@ Len's Shoryuken.

Some of the other poses look familiar, but I can't place them off the top of my head. Any ideas?

Maybe whoever did this has experience with MUGEN.

Meiko looks like... hum, a punk with cape and shoulder pads, maybe Bison/Vega from SF, the others are just too common

Meiko is Wolfgang Krauser from the Fatal Fury series.

Miku is Rolento from the Street Fighter Alpha series.

I don't recognize Luka offhand.

Ahh yeah, Krauser, I was trying to figure out where the cocky "hands pressed together" pose was from.

Rin's stance looks familiar too.

Oh, Rin is just Ryu. I didn't even think to mention that.

Meiko is more like M.Bison in my opinion (or Vega if you're Japanese).

Luka is I-No you damn bitches

Alot of these remind me of Dungeon Fighter Online Edits
