Boomer Kuwanger

Boomer Kuwanger (ブーメル・クワンガー Būmeru Kuwangā), renamed Boomerang Kuwanger in Mega Man Maverick Hunter X, is a boss in Mega Man X, a Reploid based on the stag beetle ("kuwagata" in Japanese). He was a Maverick Hunter from the 17th Elite Unit under Sigma, the same unit as his brother Gravity Beetle, and fought alongside X many times. He is a nihilist that doesn't agree or disagree with Sigma's motives, and joined the Maverick uprising simply because he thought "isn't this more interesting?" He took control of a tower that was supposed to be the symbol of a city, and turned it into an oppressive fortress. Within, he sits plotting, sneering at the despair in the city below.

In the remake, Kuwanger makes decisions based only on logic and 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. When X reached the top of the tower, Kuwanger saw that X had great potential and thought that he would be fun in a fight.
