Sagat, Ken, Ryu, Akuma. This illustration was made by Japanese artist Edayan who has worked on multiple Street Fighter games. These dynamic illustrations are the last Street Fighter characters he drew for Capcom.
Akuma (in Japanese, "Devil" or "Demon") known in Japan as Gouki (豪鬼 Gōki?, lit. "Great Demon") Akuma made his debut in Super Street Fighter II Turbo as a secret character and hidden boss. In the storyline of the Street Fighter video games, he is the younger brother of Gouken, Ryu and Ken's master.
In case you didn’t know, there’s a special Gamestop Ryu’s “Battle Costume” pre-order skin for Street Fighter V. http://kotaku.com/street-fighter-vs-bearded-ryu-is-the-hott… He’s so magnificient he might probably question your own sexuality.
