### Input: Characters
The original Street Fighter II features a roster of eight playable World Warriors. This includes Ryu and Ken—the main protagonists from Street Fighter—plus six new international newcomers. In the single-player tournament, the player fights the other seven main fighters, then the final opponents—a group of four CPU-only opponents known as the Grand Masters, which includes Sagat from Street Fighter.

Playable characters:

Ryu, a Japanese martial artist seeking no fame or even the crown of "champion", but only to hone his Shotokan Karate skills with the inner power of Chi, he dedicates his life to perfect his own potential while abandoning everything else in life such as having no family, and few friends, his only bond is with Ken. He is the winner of the previous tournament. He is not convinced that he is the greatest fighter in the world and comes to this tournament in search of fresh competition.
E. Honda, a sumo wrestler from Japan. He aims to improve the negative reputation of sumo wrestling by proving competitors to be legitimate athletes.
Blanka, a beast-like mutant from Brazil who was raised in the jungle. He enters the tournament to uncover more origins about his forgotten past.
Guile, a former United States Air Force special forces operative seeking to defeat M. Bison, who killed his best friend Charlie.
Ken, Ryu's best friend, greatest rival and former training partner, from the United States. Ryu's personal challenge rekindled Ken's fighting spirit and persuaded him to enter the World Warrior tournament, as well as feeling lackadaisical in his fighting potential due to spending too much time with his fiancée.
Chun-Li, a Chinese martial artist who works as an Interpol officer. Much like Guile, she does not enter the World Warrior tournament for any personal glory except proving that she can defeat any man who challenges her. Chun-Li's ambition in the past was tracking down the movements of the smuggling operation known as Shadaloo. Her goal now is her trail being led to the tournament by seeking to avenge her deceased father by holding the Grand Master's leader of the crime syndicate responsible.
Zangief, a professional wrestler and sambo fighter from the Soviet Union. He aims to prove "Soviet Strength" is the strongest form of strength, particularly by defeating American opponents with his bare hands.
Dhalsim, a fire-breathing yoga master from India. Even though he is a pacifist, he uses the money earned from fighting in order to lift people out of poverty.
CPU-exclusive characters, in the order of appearance:

Balrog, an American boxer with a similar appearance to Mike Tyson. Called M. Bison in Japan. Once one of the world's greatest heavyweight boxers, he began working for Shadaloo for easy money.
Vega, a Spanish bullfighter who wields a claw and uses a unique style of ninjutsu. Called Balrog in Japan. He is vain and wishes to eliminate ugly people from the world.
Sagat, a Muay Thai kickboxer from Thailand and former World Warrior champion from the original Street Fighter. He was once known as The King of Street Fighters until he got demoted as The King of Muai Thai in his own tournament due to a narrow defeat at the hands of Ryu's shoryuken (rising dragon punch) which left a deep gash across his chest. Ever since that moment he felt disgrace, and will do anything to have a grudge match with Ryu to get his title back, even if it takes joining forces with Shadaloo.
M. Bison, the leader of the criminal organization Shadaloo, who uses a mysterious power known as Psycho Power, and the final opponent of the game. Called Vega in Japan.
