The original Street Fighter was released in 1987. It was overlooked by the vast majority of arcades at the time. Only two characters were playable, player 1 was Ryu and player 2 was Ken. Ryu is Japanese and Ken is the son of a rich American family. They are both students of shotokan karate. Ryu is an orphan who wants to be the best fighter in the world while Ken was sent to Japan to train because he was getting too out of control as a teenager. They both studied under the shotokan master Gouken.
The game begins in Japan where Ryu and Ken must defeat fellow shotokan student Retsu to prove they were ready to enter the tournament. They travel around the world until they have defeated all the other street fighters in the tournament. They then face the champion of the street fighter tournament, Sagat, a kickboxer from Thailand. Ryu defeats Sagat with a dragon punch(sho ryu ken) that is so powerful it scars Sagats chest. Sagat vows to one day get revenge.
