Tokido is one of the original 5 Gods of the Japanese Fighting Game Scene, along with Daigo Umehara, Nuki, Sako, Haitani. His skills are born out of the fierce Japanese arcade scene and they carried over into his competitive play at tournaments. He has the nickname "Murder-face", because of his deadly-serious expression while playing. He took 1st place at both Capcom Pro Tour Premier Events CEO 2016 and SEAM 2016.
Akuma is a cold and extremely powerful warrior whose sole reason for being is to hone his fighting skills by battling and destroying strong foes. He rarely displays any sign of emotions, aside from occasional bursts of anger, and rarely smiles. He takes his training very seriously and deals brutally with those who dare interrupt him, as seen in his Street Fighter III: 3rd Strike ending. Occasionally, he likes to test himself against worthy rivals (e.g. Gen, Oro). In later games, Akuma often refers to himself as a "denizen of hell" and "evil incarnate", and is seen as such by many. This may be a result of the Satsui no Hado ("Surge of Murderous Intent") taking a toll on his mind.
Ryu is a silent, meek, humble, submissive, self-deprecating, and respectful individual; which is often juxtaposed against the light-hearted, fiery persona of his childhood friend, Ken. He wanders the world with the desire for complete mastery of his martial art, and takes both his travels and training seriously. For Ryu, the training and the mastery that comes from the fight are all that he requires for satisfaction, declining the more material trappings of his various accomplishments as a warrior, simply moving on to his next challenge once he is victorious without delay, unless he is offered food or if he wants to converse with his friendly rivals.
While Ryu is the more serious and stoic of the two, Ken is the complete opposite - flamboyant, unorthodox and unpredictable. 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.
