Bubble Lead

Bubble Lead (バブルリード) is Bubble Man's main weapon. It throws a heavy bubble that rolls in the floors. If used against Bubble Man in the final stages, it will recover all of Bubble Man's health. It bounces instead of rolls when used by Bubble Man. It's Heat Man's weakness, but Heat Man is immune to the Bubble Lead when he's fully ignited or when doing his fire charge attack. The Bubble Lead can also scale down walls (but only down) and can only do so if the bubble is rolling on the ground in the first place.

The Doc Robot from Mega Man 3 also used this weapon along with the weapons from the other Robot Masters from Mega Man 2, but the player can't take it from Doc Robot. Mega Man is equipped with the Bubble Lead in the scenes shown by Rush in Mega Man 9's ending.

Trivia

 * There has been some debate over the weapon's real name. Some say it is Bubble Lead (pronounced led, as in a lead pencil), signifying that the bubble is made of heavy lead. Others say it is Bubble Lead (pronounced leed, as in leading a horse to water), signifying that the bubble can lead Mega Man since it travels along in front of him, and in fact can be used to find the hidden floors in one of the Wily Levels at the end of MM2. The Japanese name of the weapon is pronounced in this latter way.
 * The Bubble Lead has a similar appearance to the Bubble Bomb in MegaMan V.
