Confirmed by both Famitsu magazine and biographer Florent Gorges, game developer Yoshihisa Kishimoto has passed away at 64. Kishimoto’s bare-knuckle influence on gaming is far longer than an outstretched punch. The arcade hit Nekketsu Kōha Kunio-kun (released in the U.S. as Renegade) not only spun into two everlasting series but defined video game beatdowns as we know them.
Kishimoto began his career at Data East, working on Laserdisc responses to Dragon’s Lair like Road Blaster and Cobra Command. Speaking to Polygon about the history of Double Dragon, Kishimoto said that intense youthful emotions fueled the creative drive behind those games. “There was a girl and she dumped me,” he told Polygon, “which pulled the trigger.”
He then channeled the feelings into a new game, 1986’s Nekketsu Kōha Kunio-kun, a blend of Bruce Lee’s ultra-popular movie Enter the Dragon and elements of his own rebellious youth. Following protagonist Kunio-kun, Kishimoto’s self-insert, you pummeled local nogoodniks to protect your best buddy.
Je suis abattu en apprenant le décès soudain de mon ami Yoshihisa Kishimoto, l’un des game designers les plus incroyables de l’histoire du JV. Il avait accepté que je devienne son biographe et c’était l’une des plus grandes fiertés de ma vie. Il va me manquer. Merci à lui. 🙁 pic.twitter.com/8PTnELg3jE

It wasn’t the first beat-em-up, but the player’s ability to maneuver around an isometric space and choose different paths added the “scrolling” ingredient that would usher the genre into arcade royalty. When it was localized to worldwide markets, the controversial high school delinquent angle was dropped for a more reactionary urban bedlam look, and the game was retitled Renegade. This cultural split happened to birth not one but two legendary gaming series: Double Dragon and River City Ransom.
Kunio-kun was such a hit for publisher Technōs that he became their mascot, albeit squatted down into a cuter appearance and starring in athletic games. The next Kunio-kun game to leave Japan was Downtown Nekketsu Monogatari, better known as River City Ransom. It added spry, whip-fast combat and RPG elements as Kunio-kun and former rival Riki scrap their way across town. Kishimoto wasn’t directly involved with the development of Ransom, but he’d revisit it throughout his career with games such as 1994’s River City Girls Zero on the Super Famicom and 2019’s Stay Cool, Kobayashi-san!: A River City Ransom Story.
Kishimoto’s attention was more focused on what would become Double Dragon. Originally envisioned as the third brawler entry in Kunio-kun’s saga, development leaned toward something resembling the international version of Renegade. Instead of Kunio-kun and Riki, the game now starred new characters, twin brothers Billy and Jimmy Lee, rescuing girlfriends from mystical mutant gangs in the post-apocalyptic wastelands.
Double Dragon was Kishimoto’s biggest hit yet, generating heaps of sequels, ports, remakes, crossovers, fan games, an animated series, a really weird movie starring Mark Dacascos, Alyssa Milano and Robert Patrick, and a game based on that really weird movie starring Mark Dacascos, Alyssa Milano and Robert Patrick. Like with River City Ransom, Kishimoto would regularly revisit the Double Dragon series as director or producer, even as recently as 2017’s Double Dragon IV.
Kishimoto leaves behind a staggering legacy, not just in brawling games like Streets of Rage and Konami’s Ninja Turtle run, but through a very clear influence on Street Fighter’s urban brawls and on fighting games at large. The semi-autobiographical Renegade fractured into two distinctive and beloved series, and those little echoes of Kishimoto to continue the fight.
Mitsuhiro Yoshida, who directed River City Ransom, passed away in 2022.
