So essentially, in Akuma's first appearance his name was "The Ancient One." That's cool. He also made an appearance at the end of the credits.

Another gaming landmark: Akuma's first use of his Constipation Stance
You were left completely in the dark as to who this guy was. True, it wasn't long before Capcom revealed a long, winding backstory about how he was Ryu and Ken's master's brother, and was possessed by Dark Hadou or whatever, and went around killing people, and sunk a submarine, and keeps challenging Ryu, and stuff. Ignore all of what came after, and look at his first ever appearance. You did not know who this man was. You did not know where this man came from. All that mattered was what he was going to do to you, and that you were in the toughest fight of your life. Akuma was a nightmare, and the mystery behind him was a really good thing, especially when you consider how much he's been overused since. In his first appearance, however, Akuma was the epitome of cool.

Not one of Akuma's finest moments.

Also not one of Akuma's finest moments.

The less said about this, the better.
