Killer Bomb (キラーボム,Kirā Bomu?), known as Killer Bullet in some English sources, is an industrial bomb robot created to explode distant objects. In the first Mega Man game, they appear as enemies in Bomb Man's stage, Fire Man's stage and in Dr. Wily's Robot Manufacturing Plant that explode on impact or when damaged.
An industrial robot created to blow up distant objects. You'll take damage if it detonates too close to you.
Killer Bombs, along with Pipis, Bomb Man and Napalm Man, were part of Dr. Wily's attack on the city in the Mega Man cartoon show opening. They only make their cameo in the opening and don't appear in any of the episodes.
Killer Bombs look similar to Bullet Bills from the Mario series, especially the Banzai Bill variety from Super Mario World. Also of note is that Bullet Bills are known as "Killers" in Japan, and Killer Bombs are known as Killer Bullets in some English sources, such as the first game's manual and in Mega Man Powered Up.
