The fighting style used by Dhalsim is Yoga. In Street Fighter, Dhalsim is an Indian yogi whose supernatural abilities are presented as extensions of his mastery of yoga, allowing him to stretch his arms, legs, abdomen, and neck across unusual distances.
Dhalsim debuted in Street Fighter II: The World Warrior in 1991. His design combined the development team’s ideas of India and yoga, while his long-range attacks made him play very differently from close-combat fighters such as Ryu or Ken. His signature moves include Yoga Fire, Yoga Flame, Yoga Blast, and Yoga Teleport.
The answer is sometimes confused with a conventional martial art such as karate or kung fu. However, the games consistently identify Dhalsim’s fighting style as a Yoga-based style. His fire attacks and teleportation are fictional powers associated with the series’ mystical interpretation of yoga, not ordinary real-world yoga practice.
