Unknown by public, only Keiji Inafune himself (and probably just a few Capcom staffs) knows who he is and how he is right now.
"The infamous MegaMan (which which was drawn and painted overnight due to a rush schedule, by an art student friend [of] Keiji Inafune, The producer), showing a horrible rendition of a strangely dancing MegaMan character, in a billowing yellow and blue Hammer-Time style jump suit, WAVING A PISTOL"

I like how he was a friend of someone who probably knew the character well, but was still put on the spot to make the cover art in a day. Either Inafune was a jerk not poviding him some demos, screenshots or even a byro sketch, or the artist was like:
Inafune: I know this is last minute, but I need you to make cover art for the Megaman game by tommorow. I can provide you some screenshots to help with-
[Unknown artist]: "Nah, I got this."
Inafune:N-no, I don't think you got-
[Unknown artist]: I said I got this.
[Unknown artist]: I don't got this.
Oh well, maybe no one will know?
