Yun (ユン) is a character in the Street Fighter series. He first appeared in Street Fighter III. He is also a playable character in the arcade version of Super Street Fighter IV. Out of the two, Yun is the most extroverted and has the most attitude in comparison to his more humble, younger twin brother Yang.
With his twin brother Yang, he entered the third World Warrior tournament to show his skills. They later found and fought Gill, who appreciated their effort and granted them leadership of their town. They passionately turned down his offer, since they only fought him to stop his maniacal plans.
