Is it Q?

In Ken's stage in Street Fighter II The World Warrior there is a guy with a hat, coat and a grey face like Q of Street Fighter III Third Strike (who was not yet invented back then).

Chun-Li in Final Fight 2 Easter Egg appearance
(Ken's SFII stage; probably not Q of SFIII)

Depending on what version of SFII you're playing, his face can have a more usual tone so it's most likely not an easter egg appearance of Q, just a coincidence. Q also wouldn't raise his hand like that.

(thanks to Fenrir from Ryu's Temple, a French Street Fighter site that also state's that it's not Q)
