>Super Dodgeball (Nekketsu Kōkō Dodgeball Bu) (Arcade, NES, X68000, and at some point PC Engine, Game Boy port later, and eventually a sequel on SNES, then an all-new remake for Neo Geo)
Lead Kunio and his gang to victory by finding a way to beat the life out of everyone with only a dodgeball. The PC Engine version, Nekketsu Kōkō Dodgeball Bu: PC Bangai Hen, is a special version of the original Dodge Ball which combines the graphics and teams of the arcade version with the emphasis on character-specific statistics and team formation. Features an arcade-style mode and a plot-oriented Quest Mode where Kunio gets his ass beat by a fucking alien and he and his crew have to euthanize them with dodgeballs.
>Nintendo World Cup (Nekketsu Kōkō Dodgeball Bu: Soccer Hen) (NES, X68000, Game Boy, at some point the PC engine, and ironically enough the Sega Drive)
Play some soccer/football and beat the shit out of the opposing team on the way. There's really not too much to say, it's simple as it gets. I think the PC Engine version (Nekketsu Kōkō Dodgeball Bu: CD Soccer Hen) is the definitive edition but I'm not too sure about that.
>Downtown Nekketsu Kōshinkyoku: Soreyuke Daiundōkai (NES, PC Engine, and later Game Boy)
A game that can be played with up to 4 players. Lead Nekketsu against 3 other rival schools in four different competitions, no holds barred, and beat the shit out of them too.
>Ike Ike! Nekketsu Hockey Bu: Subette Koronde Dairantō (Unreleased Title: Crash 'N The Boys: Ice Challenge) (NES)
One of Kunio's pals has self-esteem issues with his hockey team. Kunio uppercuts the fuck out of him and tells him to be a man, and then takes charge of his own hockey team and goes on a rampage. In short, hockey but you beat the shit out of everything. This was meant to be released in the US as the noted unreleased title, but for some reason never went far.
>Crash 'N The Boys: Street Challenge (Bikkuri Nekketsu Shinkiroku: Harukanaru Kin Medal) (NES, Game Boy)
Kunio's bloodlust grows. Now no longer content with beating the shit out of people with hockey sticks, he resorts to spiking people like they Post too long. Click here to view the full text.
