Boomer Kuwanger (ブーメル・クワンガー),[4] also translated as Boomerang Kuwanger,[1][5] is a Maverick from the X era, first appearing as one of the main bosses in Mega Man X. He is a cutter-themed Reploid based on a stag beetle (クワガタ), with the ability to phase in and out of reality and throw the curved blade from his head.

Like the rest of the Mavericks in the first game, he was previously part of the Maverick Hunters, specifically serving in the 17th Unit alongside X and Zero.

In the Games

Mega Man X

Sprite from Mega Man X.

Boomer Kuwanger debuts in Mega Man X as one of the eight Mavericks on the Stage Select screen. He serves as the boss of Tower Stage. The Japanese game manual states he is a former Maverick Hunter of the 17th Elite Unit who joined Sigma's rebellion, and has converted a city's iconic tower into his personal stronghold.[6]

Boomer Kuwanger's fast footwork can make him difficult for an inexperienced player to avoid, but his high recoil from the X-Buster is one of his biggest weaknesses. Defeating Boomer Kuwanger grants X the Boomerang Cutter. His weakness is the Homing Torpedo, from Launch Octopus, which is also useful for its ability to home in on Kuwanger despite his speed. A boss attack rematch with Boomer Kuwanger later occurs in Sigma Stage 1, being the very first.

Mega Man Maverick Hunter X

Render from Mega Man Maverick Hunter X.

In the remake Mega Man Maverick Hunter X, Boomerang Kuwanger's name is retranslated and he receives a redesign, but he plays largely the same role as in Mega Man X, being the boss of Fortress Tower. He is one of the few Mavericks besides Sigma to recognize X's potential, but only cares about fighting him. In battle, for X he is still weak to Homing Torpedo and yields Boomerang Cutter upon his defeat, while for Vile he is weak to weapons obtained from Launch Octopus (Humerus Crush, Popcorn Demon, Banzai Beetle, Lost Lamb, Serotinal Bullet) and yields the Cutter weapon system. Kuwanger's boss attack rematch later occurs in Sigma Palace 1.

Mega Man X DiVE

In Mega Man X DiVE, Maverick Data of Boomerang Kuwanger appears as the boss of the event Space-Time Jumper. His defeat unlocks the Chip for Boomerang Cutter. He also reappeared as a boss in Co-op and Jakob.

Official Data

Source Data
Rockman X manual A Reploid who belongs to the 17th Unit, the same as X. The reason he joined Sigma was because he thought "Isn't this more interesting?" He has taken over an iconic tower, which was meant to be the symbol of a city, and is converting it into a fortified stronghold. He is a cynical nihilist who is somewhat elusive.[JP]

Compendium of Rockman X Boss File A comrade of X's from the 17th Unit. He participates in the rebellion because "isn't it more interesting?" He takes over a tower and converts it into a fortified stronghold that repels all intruders.[JP]
Mega Man Maverick Hunter X manual Comes from the same 17th Battalion as X. Excels in collecting and analyzing combat data with an extremely cool logic. With no sense of justice or evil, joining Sigma's rebellion is a decision he arrived at after analyzing the case rationally. He has taken over the tower that was to be the symbol of the city, and is working to convert it into a base.
Mega Man X Legacy Collection Gallery A fellow member of the 17th Unit, the beetle-like Kuwanger fought alongside X and Zero many times. He doesn't agree or disagree with Sigma's motives; he simply joined the uprising because it looked like more fun. The high-rise tower he has taken over should have been a shining symbol of the city's progress, but instead it has become an oppressive fortress. Within, Kuwanger sits plotting, sneering at the despair in the city below.
Mega Man X DiVE It is previously the member of Irregular Hunters of the Seventeenth Elite Squad. Its rapid movement makes it hard to locate. Its horns can serve as a boomerang and can pierce through enemies.[sic]


Behind the Scenes

Developer Commentary

"Inafune did Eagle and Penguin, Kaji designed Mandrill, Octopus, and Chameleon. Mammoth, Armadillo, and Kuwanger were Tazaki's. Even as I watched them work, I could really see each of their distinct flavors coming out in their illustrations." - (Tatsuya Yoshikawa)[3]


Language Name Origin
Japanese Boomer Kuwanger (ブーメル・クワンガー) "Boomer" is derived from boomerang, and "Kuwanger" is a portmanteau of "kuwagata" (クワガタ), meaning stag beetle, and boomerang.
English Boomer Kuwanger
Boomerang Kuwanger
Maintains his Japanese name. In later translations, "Boomer" was extended to "Boomerang" likely to make his weapon theme more evident.
