Napalm Bomb

Napalm Bomb (ナパームボム) is Napalm Man's special weapon. When Mega Man uses it, he sends out a bomb that bounces about on the ground. It explodes if it kills an enemy on contact, or after a few seconds of no activity. It will change direction if it hits a wall. It's useful against low-lying enemies like Mousuberu.

The Bridge from Mega Man IV and the second Weapons Archive of Mega Man 10 are also able to use the Napalm Bomb.

Capacity
It costs one weapon energy unit per bomb in Mega Man 5 and Mega Man IV. With a full weapon energy gauge, it can shot a total of 28 bombs in Mega Man 4, 19 bombs in Mega Man IV, and 7 bombs in Mega Man: The Power Battle.
