Madbomber

Madbombers (usually referred to as Bombermen in the Bomberman series) are robotic people similar to Bomberman. In the Mario franchise, they made their only appearance in Wario Blast: Featuring Bomberman!, Wario invades Bomberland to loot Bomberland, as well as taking the Madbombers for his side. The Madbombers resist with their bombs. There are two functionally-identical types of Madbombers that differ only in appearance - Wario (namely, multiple copies that presumably have the same goal) and other bombermen. [sic]

The Madbombers have the same starting abilities as Bomberman and Wario. They can lay bombs and collect and utilize the same powerups. Upon completion of the Normal Zone, the Madbombers gain the same Kicks ability, however, they do not obtain any of the other special items that the player gets upon completion of later rounds. There is always a single Madbomber to face in the first stage of each round, with one more added for each additional stage. In the fourth stage, the three Madbombers unite to form the boss of the round.

They display minor differences from Bomberman in the sprites, such as one having a visor, and another having a striped helmet. The Wario enemies display no differences from Wario aside from Palette.

In the original Bomberman GB, the group of Bombermen mugged Bomberman, so he had to fight them in order to retrieve his belongings.
