Play Kunio kun Nekketsu Collection 1 (J)(WRG) Online

Kunio-kun Nekketsu Collection 1 is a Japan-only Game Boy Advance compilation released in 2003, developed by Million and published by Atlus. It gathers several early titles from the long-running Kunio-kun series, originally from the 8-bit era, offering a solid dose of retro beat 'em up action on a handheld that was otherwise full of more modern, polished games.

You control Kunio or one of his rivals, moving through urban environments and beating up waves of delinquents with punches, kicks, and grapples. The main goal is simply to clear each area of enemies, often advancing screen by screen while occasionally facing a boss. Signature mechanics include picking up environmental objects like rocks or bikes to use as weapons, and executing special throws once you grab an opponent. The pacing is fast and straightforward, though the enemy aggression and limited continues can make certain stretches challenging. It feels like a direct, no-fuss translation of arcade-style brawling meant for quick sessions and replaying with a friend.
