Ken is the deuteragonist of the Street Fighter series, first appearing in the original Street Fighter. Similar to his longtime best friend and rival Ryu, Ken's goal is to test his power against many different fighters and strives to become stronger, but holds more restraint due to not wanting to jeopardize his family life.
While Ryu is the more serious and stoic of the two, Ken is the complete opposite - stylish, unorthodox and unpredictable, as well as being much more violent and aggressive than Ryu. He is an alpha male with a giant ego and constantly reminds his opponents about his greatness. While he can be brash, egotistical, and arrogant at times, his heart is pure. He is generally kind, friendly, a good person, and very easygoing which led him into starting a family of his own. He never backs down from a fight no matter how difficult it looks.
Super Smash Bros. Ultimate
Ken is one of the many playable characters in Super Smash Bros. Ultimate. He serves as Ryu's Echo Fighter. His inclusion was leaked on September 21st, 2018 through a screenshot, before his official reveal on November 1st alongside Incineroar and Piranha Plant. Despite being classified as an Echo Fighter, Ken falls more in line with the definition of a semi-clone, having more unique moves and differences from his base fighter compared to any other Echo Fighter pairing.
- Ken is the second playable character in the Super Smash Bros. series to have two Final Smashes in his moveset, after Ryu.
- Ken is the second fighter to originate from a fighting game, the first being Ryu. They were both later joined by Terry Bogard.
- Ken is the only Echo Fighter that is a semi-clone rather than a full clone.
