Advance Guardian Heroes is a pseudo-sequel to Treasure’s unusual Saturn brawler. Unlike its predecessor, this game uses a standard free-roaming brawler system rather than the three lane setup of the original. It still features magic attacks and light RPG elements, though. Additionally, it adds a unique death system where you have the option to play through the rest of the stage with invincibility when you die (although it’s Game Over when you finish the level.)

Battletoads for the Game Boy is a unique ’Toads game that takes the basic gameplay mechanics from the NES original and creates entirely new enemies, stages, and bosses. Like other games in the series, it has very little pure brawler gameplay and instead focuses on variety sections such as action-platformer stages and space shootin’.

Battletoads & Double Dragon: The Ultimate Team is a crossover brawler from Rare that features your two favorite brawler franchises together for the first time. It plays a lot more like a ’Toads game than Double Dragon, with a strong emphasis on vehicle and platforming sections over combat. However, its difficulty is far more tame. The Game Boy port is remarkably similar to the NES version (including all stages) yet it lacks two player support.

Battletoads in Ragnarok’s World is a port of the original NES ’Toads game to the Game Boy. Although it maintains the original’s mechanics and focus on variety, it lacks two player support and has about half as many stages. The levels it does include are arguably the most memorable, such as the rappelling section, hoverbike stage, and snake area.

Dancing Sword: Senkou is a Japan-exclusive GBA weapons-based brawler featuring an all-female cast of five fighters. Its combat focuses on alternating the two attack buttons to perform various combos. It also features Survival and Training modes.

Double Dragon for the Game Boy is a pseudo-port of the NES version. It has most of the attacks from that version, but it drops the XP mechanic and changes around stages and enemy placement. Like the original, it’s a single player game.

Double Dragon is a unique entry in the series made for Game Gear by Virgin. It abandons the series’ trademark combat and style in favor of plagiarizing Streets of Rage. Billy looks almost exactly like Axel, and the title music is a Streets knock-off instead of the Double Dragon theme. Its combat is a simple punch/kick system with a small handful of weapons including guns.

Double Dragon III: The Arcade game is the final release in the Double Dragon Game Boy trilogy. Unlike the first two games, this one is based off the Arcade version instead of the NES one. It’s combat is brutally difficult, but you can buy extra health, lives, damage, and attacks from shops in each stage. It also has two player support.

Double Dragon Advance is a GBA-exclusive DD game featuring eight stages and two-player gameplay via link cable. It incorporates stages, enemies, and attacks from the original trilogy as well as adding new content. It features the largest moveset the series has ever seen, huge gangs of enemies, and additional modes such as Survival and a 1P Double Dragon setting where you can switch off between the Lee brothers at will.

Double Dragon II is the second DD game on the Game Boy, and the first on the system to feature two-player brawler gameplay. Its combat is more similar to the original Double Dragon than The Revenge. It also replaces the jump with a crouch that can be followed up with a flying uppercut. This game is actually a re-working of Nekketsu Kouha Kunio-kun: Bangai Rantou Hen with new graphics and music yet identical stages and gameplay.

Downtown Special: Kunio-Kun no Jidaigeki Dayo Zenin Shuugou! is a faithful port of the Japanese-exculsive NES brawler of the same name.

Like the original, this version features two player gameplay as well as an AI-controlled partner in single player.

The combat is fairly standard although you can switch between characters at will and it has energy-based projectile attacks.

Dynasty Warriors Advance is a hybrid strategy game/RPG/brawler from Koei. After choosing one of three factions with three unique fighters each, you fight the enemy by moving on a map screen which transitions to beat ’em up gameplay when you make contact. Its combat focuses on alternating the two attack buttons as well as upgrading your stats on the fly.

Final Fight One is a port of Capcom’s timeless arcade classic to the GBA. Although it features the same graphics as the SNES port, it restores Guy and the missing industrial stage as well as adding system-link co-op gameplay. It also features tons of onscreen enemies, remixed enemy waves, alternate costumes for Cody and Guy, and boss cutscenes.

Ganbare Goemon: Sarawareta Ebisumaru! is a Japanese-exclusive exploratory Game Boy brawler from Konami. It’s obviously part of the Ganbare Goemon series, which is known as Legend of the Mystical Ninja in the US. Like the Goemon games on the NES, it features light brawler gameplay with an emphasis on light RPG elements such as exploring towns, finding items, and fulfilling objectives to proceed.

Gekido Advance is a GBA-exclusive single-player brawler that emphasizes adventure elements such as exploring mazes, dodging traps, talking to townsfolk, and solving quests. Its graphics features smooth animation with an anime style like a King of Fighters game. Its combat emphasizes alternating the two attack buttons to perform various combos as well as picking up a multitude of powerups.

Guilty Gear Judgment is a spin-off of the Guilty Gear series of fighting games from Arc System Works for the PSP. Although it’s a brawler, it features many qualities of the original such as a ton of playable characters, gigantic advanced movesets, fluid animations, and rapid gameplay. Besides that, it’s a traditional beat ’em up in terms of enemy design and structure. It has 2-player co-op gameplay via the PSP’s ad-hoc multiplayer as well as a standalone fighting game in addition to the brawler portion.

Jackie Chan Adventures: Legend of the Darkhand is a GBA-exclusive brawler based on the kids’ animated cartoon show starring Jackie Chan. Its two-button combat engine emphasizes scoring. It features multiple difficulty settings and an optional Training mode.

Justice League Heroes: The Flash is a superhero-themed GBA-exclusive brawler from WayForward games.

Nekketsu Kouha Kunio-kun: Bangai Rantou Hen is an original Kunio game for the Game Boy. Its combat engine is actually more similar to the very first Kunio game (i.e. Renegade) than Downtown Special (aka River City Ransom.) It also adds a crouch move that can be followed up with a mighty spinning uppercut as well as a gut-jumping attack. It features three difficulty settings and link cable support for two-player gameplay.

Ninja Boy is a martial arts-themed overhead brawler from Culture Brain. It features simple combat with only a few attacks and small stages where you have to beat a certain number of enemies to proceed. It emphasizes collecting items over the course of the game so you’re powerful enough to defeat the later enemies and bosses. This game is basically a port of Kung Fu Heroes on the NES.

Ninja Boy 2 is a hybrid RPG/brawler for the Game Boy. It’s a loose port of Little Ninja Brothers on the NES, although it’s only single player and the story has changed. You travel around an overhead map, talking to townspeople and taking on quests like an RPG, but when you encounter an enemy the game switches to traditional brawler combat. You also gain experience and can buy items to help you on your mission.

River City Ransom EX is a souped-up port of Technos’ beloved NES RPG/brawler hybrid. In addition to maintaining the signature gameplay and style of the original, it adds new attacks, reworked graphics, AI partners, and a new honor system. It also has system-link co-op gameplay.

Streets of Rage for the Game Gear is a semi-faithful port of Sega’s beloved Genesis classic. Although it removes Adam, some stages, and some attacks, it gives a semblance of Streets’ gameplay and challenge. It also features simultaneous 2-player co-op action. Its OST is a combination of tracks from Streets of Rage 1 and 2.
