"Go to heaven."
Retsu (烈, lit. "Furious") is a non-playable character in the first Street Fighter game as one of the ten CPU Fighters.
Just before the first World Warrior tournament, Retsu was indefinitely excommunicated from his temple for using forbidden techniques. After losing to young Ryu, he has since strived for repentance and is training to further improve his martial arts.
Though unplayable in the vanilla build, he has been made playable in the SF1++ hack.
Retsu is a fairly honest character, being able to play good defense and offense. His HK has some of the best range of any normal in the game, making him quite the wall. The upsides stop there, his frame data is rather poor and most of the cast can low-profile his jump attacks, and his approach is poor and unthreatening, usually consisting of unsafe jump attacks or walking slowly forward and Heavy kicking. Without any safe and rewarding burst options, he has no mix game and usually just gets baited and punished these days. Some matchups are Functionally impossible for him such as mike and Ken who Retsu simply lacks the tools to fight in any real sense. In the match-ups he can play he mostly tries to gain health lead since his zoning tools are far stronger than his approach options. Retsu's is a masochist dream at high level but for casual play he can be quite fun.
In SF1++, Retsu is selected by holding 
at the title screen or VS. Screen and pressing Start.
