The Mishima corporation is one of the richest conglomerates on the planet, and its owner, the legendary fighter Heihachi Mishima, is now sponsoring a martial arts competition – whoever can best the other competitors and finally defeat Heihachi himself will be awarded both wealth and the title of King of Iron Fist. But money and fame are not the only factors drawing fighters to the competition, as Heihachi has made many enemies over time – his son Kazuya being one of them.

As a mysterious scientist emerges with plans to harness the power of the world's strongest fighters, Ryu must confront and destroy this new enemy before all of mankind is enslaved. With the lives of his friends hanging in the balance, can Ryu overcome the evil power within, before it completely consumes him?
Throughout the world, fighters have begun to suddenly disappear - all of them masters in their particular combat discipline. Guile and Chun Li are assigned to investigate the situation and find out what they can. Meanwhile, Cammy's Delta Red team has investigations of its own to make, as a mysterious force seems to have torn a hole in the Amazon jungle. At the same time, a secret agent seems to be tracking Ryu, and it's not long before everybody else's eyes are on the legendary and elusive fighter. But Ryu has problems of his own; is he really able to control the power of the Dark Hadou which wells inside him?
This anime is a spawn of one of the good ol' classic fighting game, like Tekken, both go back a long way. Both have pretty kickass fighting scenes which relive the ingame moves the characters use, as well as being true to the games' storylines.
Although they both have similar 'trials' they must go through in order to achieve what they wish, Street Fighter follows Ryu closely as its main protagonist whereas Tekken has multiple main protagonists, the most prominent being Jun Kazama, Kazuya Mishma and Jin Kazama.
Both animes have enjoyable plot moments and a story that you can really get into, especially if you love martial arts and character development. But hell, whatever type of anime person you are you won't be disappointed as you find yourself watching them again and buying the games :).
