His improved Shoryuken ki techniques, mixed with the many other attacks at his disposal, make him a very capable and unpredictable opponent. While Ryu specializes in using his Hadouken based ki attacks, Ken has mastered and has enhanced the ki of the Shoryuken to a powerful effect. Although his core fighting techniques are similar to Ryu's, their current training methods and overall personalities create subtle differences between them. Unlike Ryu, who tries to learn new things from fighting to become a better warrior to help rid himself from the Satsui no Hadou, Ken has a loving relationship with his wife Eliza, with whom he has a son named Mel. He has dyed blonde neck-length hair and a bright red uniform, which he uses to intimidate his foes in the ring. Ken has entered all kinds of martial arts tournaments and won many titles from his tours around the world. Ryu is Ken's best friend, training partner and later a friendly rival.
He trained in the martial arts alongside Ryu under Master Gouken as a young boy. Ken was born in the USA and is a proud member of the multi-billionaire, Masters family.
