In Mega Man 2, which robot master grants the Bubble Lead weapon?

In Mega Man 2, Bubble Man grants Mega Man the Bubble Lead weapon. Bubble Man is one of the eight Robot Masters whose stages can be tackled in any order, continuing the series’ strategy of choosing bosses to obtain useful weapons.

Bubble Lead fires bouncing bubbles that travel along the ground and can reveal or damage enemies in places Mega Man’s normal arm cannon cannot easily reach. The weapon is especially important because it is the key weakness against Dr. Wily’s alien-shaped final boss, which is actually vulnerable to Bubble Lead despite its appearance.

Bubble Man is a water-themed Robot Master, but he is not the source of every aquatic weapon in the franchise. Later games introduce Aqua Man, Tidal Man, Wave Man, and other water-related characters. Bubble Lead is also sometimes confused with Water Wave or Water Shield, weapons from later Mega Man titles. Mega Man 2 was released in Japan in 1988 and became one of the best-known entries in the classic series.
