His full name is Mikhail Segeyvech Cossack, but would likely go by the name of Sergi to shorten it. I have good word on this and was wondering if anyone had any complaints.Brick Man 21:12, 15 August 2006 (UTC)
I've been hearing talk that Dr. Cossack looks like Gordon Freeman. This is technically incorrect. Half-life was released in 1998, and Mega Man 4 was released in 1991. Dr. Cossack came first, therefore Gordon Freeman looks like Dr. Cossack.Crisis21 (talk) 05:41, August 19, 2013 (UTC)
Before anyone says I'm wrong about Cossack at one point was called Dr. Vice, Nintendo Power officially said it.MegaBossMan (talk) 05:40, January 28, 2014 (UTC)
