Gemini Laser

Gemini Laser (ジェミニレーザー) is Gemini Man's special weapon. It shoots a blue beam that can ricochet off of walls in a 45 degree angle for a while. In Mega Man 3 and Mega Man III, only one Gemini Laser can be used at time, while two can be used at the same time in Mega Man: The Power Battle and Mega Man 2: The Power Fighters. Except for Mega Man III, Mega Man can't change the weapon until the laser hit a target or vanish.

The Gemini Laser also appears as an ability of the Weapons Archive in Mega Man 10.

Capacity
One Gemini Laser uses 2 weapon energy units in Mega Man 3 and Mega Man III and 1 unit in Mega Man 2: The Power Fighters. With a full weapon energy gauge, it can be used 14 times in Mega Man 3 and Mega Man: The Power Battle, 10 times in Mega Man III, and 16 times in Mega Man 2: The Power Fighters.
