Blaze Fielding, along with Axel Stone, is one of the main protagonists in the Streets of Rage franchise for the Sega Genesis. She is a playable character in all three games.
Streets of Rage
Blaze makes her debut in 1991's Streets of Rage as one of the three cops who quit the city's corrupt police force, in order to settle the rampage that has plagued the city and find out those responsible behind those events. Along with Adam Hunter and Axel Stone, she manages to defeat the syndicate leader (later named Mr. X) in his own headquarters.
Streets of Rage 2
A year after the SOR1 events, Blaze, who has moved out of the city and became a dance teacher, discovers along with Axel and Adam's kid brother "Skate" that Adam has been kidnapped by Mr. X, who was believed to be dead in the previous battle, in order to lure Axel and Blaze to him in retaliation for his prior defeat. She and Axel set out to rescue their friend with Skate and a professional wrestler named Max Thunder who is also one of Axel's friend. They manage to reach the hidden headquarters of the Syndicate on an isolated island and defeat Mr. X once again and free Adam in the end.
Bare Knuckle III
In the original Sega of Japan produced version, Blaze, along with Axel, had rejoined the police force after the events of Streets of Rage 2. During the events of Bare Knuckle III, Axel and Blaze are being assigned to the leading two cases that will actually reveal to be interconnected: a Rakushin explosion in the Wood Oak city that could be related to the Syndicate's activities, and the disappearance of General Petrov that could lead to a war between the Lima Nations. They're being assisted by Adam, Skate and a mysterious ex-researcher named Dr. Zan.
Streets of Rage 3
The Sega of America produced version (with a slightly altered storyline to lighten the game's tone, but also a representative of the harder difficulty compared to the original version) had Blaze stay in the city after the events of Streets of Rage 2 and become a private detective. When informed by ex-researcher Dr. Zan that the next victim of the Syndicate's evil scheme will be her old friend, the Chief of Police, she immediately sets up a task force to go to his rescue.
Blaze has the role of "the female brawler": volunteering, determined, and ready to put her life in jeopardy to bring an end to the Syndicate. She is strong with a sense of justice but is ruthless towards her opponents, mercilessly beating them up on the streets and bloodying them with her fists.
Some of her quotes from the Bare Knuckle III Battle mode shows that she can't stand perverts and will often remind male opponents to stay focused on the fight, not on her body. She also seems to be somewhat proud and doesn't like to lose.
Blaze is a master of judo and sambo. Her fighting style consists of powerful judo throws combined with gymnastic moves and efficient jump attacks. She also uses powerful kicks and knee attacks, punches, uppercuts, and can also suplex her enemies when behind them, dealing massive damage. In SOR1, Blaze uses chops to attack her enemies.
In the later games, she uses her fists instead. Blue energy is used to give some of her moves a visual psychic effect. Blaze is also shown to have tremendous physical strength as she is capable of using the suplex on men significantly bigger and heavier than she is.
However, she can't suplex fat opponents in SOR1 and SOR3 as they are too heavy and will fall on her, dealing her damage instead. In SOR2, Blaze is strong enough to suplex even fat enemies. She can knock her opponents out with her fists, kicks, knees, slams, and throws and send them flying multiple feet. She is also strong enough to fight multiple enemies at once by herself, all of whom are big, burly men, and defeat them all.
