Ryu and Ken's journey feels earned because the show takes time to let them actually grow into different fighters, not just collect power-ups between tournament arcs. The animation still holds up because it commits to actual movement and weight in the fights instead of cutting away. Watch this if you want to see two kids become martial artists instead of watching martial artists fight, even if the pacing moves like they're traveling by foot.
Ryu and Ken Masters are close friends and martial artists who set out to travel the world, hoping to sharpen their skills and pick up new techniques. Along the way they encounter many different fighting styles and meet new people. Their journey takes a dangerous turn when they become entangled in a conspiracy run by Shadowlaw, a mysterious organization. Facing the evil M. Bison, the two friends must fight for their lives. The series is an adventure drama with an air of mystery.
