Blast Man was originally designed to use his explosives for pyrotechnics. However, Dr. Wily reprogrammed him to use his explosives for combat.
In keeping the tradition of bomb-themed Robot Masters, Blast Man is able to use explosives in combat. In this case, Blast Man uses sticky bombs that can latch onto Mega Man in an attempt to damage him via detonation. Also, Blast Man can throw non-sticky bombs in an arc trajectory to explode on contact. In a pinch, Blast Man can activate his Power Gear to throw larger and more powerful bombs.
