Ryu

Ryu is the main protagonist of Capcom’s popular fighting game: Street Fighter. He first appeared when he fought Lucario from Pokemon, and later fought Liu Kang from Mortal Kombat.

Backstory
Orphaned at a young age and left with no memory of his parents, Ryu was found and raised by the martial artist Gouken. Throughout most of his life, he lived at his dojo, training with Gouken, alongside his sparring partner Ken Masters. At age 23, he left the dojo and has since then continually wandered across the globe, always seeking to improve himself and wanting to meet and fight new people.
