Character- Sheng Long

Sheng Long is an inexistent character from the Villain alliance who was a hoax originating in Street Fighter. Despite being an integral character to the plot, he does not have a character number. He serves as one of the main antagonists for The Horse Arc.

Creation
The name Sheng Long comes from a mistranslated portion of the name of a special move performed by the series' main character, Ryu; the characters shō ryū (昇龍 rising dragon) from Shōryūken (昇龍拳), Ryu's flying uppercut, are shēng lóng in Chinese pinyin. This was carried into one of Ryu's quotes to defeated opponents in the English localization of the 1991 arcade game Street Fighter II, changing the Japanese quote "If you cannot overcome the Shoryuken, you cannot win!" (昇龍拳を破らぬ限り、おまえに勝ち目はない！, Shōryūken wo yaburanu kagiri, omae ni kachime wa nai!) to "You must defeat Sheng Long to stand a chance." As a result, players were given the impression that Ryu was referring to a person instead of the attack.

The Super Nintendo Entertainment System (SNES) port of Street Fighter II, released shortly after the April Fools' prank, changed the translation to "You must defeat my Dragon Punch to stand a chance." However, the English instruction manual for the SNES Street Fighter II referred to "Master Sheng Long" as Ryu and Ken's teacher. Instruction manuals for later ports to the SNES and Sega Mega Drive consoles replaced all references to Sheng Long by referring to Ryu and Ken as disciples of the "Shotokan school of karate" Sheng Long would later make an appearance in the 1993 Malibu Comics as Ryu and Ken's master. A character named Gouken was later introduced in Masaomi Kanzaki's 1993 Street Fighter II manga as Ryu and Ken's sensei, and was adapted into the series' backstory in Super Street Fighter II Turbo.

As a Villain
At the end of Advent Back, Mitsuru mistakes Athena as the killer of her horse. In Athena's final breaths, she tells Mitsuru that she was a decoy for a bigger boss. Athena says that Sheng Long is her boss. With Athena dead, Mitsuru goes out to find Sheng Long. Mitsuru and her group eventually find the alleged location of Sheng Long. On the gateway is a small note saying, "Hahahahahahahaha you ABSOLUTE DUMBASS. Sheng Long isn't real at all! -Athena." Mitsuru goes into a serious gamer rage and smashes open the gates. She pillages the buildings to find scream canisters in a package labeled with their return address.
