Force Beam

Force Beams are the deadly fast lasers found in Quick Man's stage. They fly in from the sides and instantly kill Mega Man on contact. They are more easily dodged with Time Stopper, and there are weapon energy pickups throughout the section in which they are active, suggesting that Capcom had intended for the player to use it.

Similar lasers appear in the first Rei Space stage.

They also appear in the first Sigma Stage of Mega Man X5. They have the same effect and can be avoided with Dark Hold (which has the same effect as Time Stopper). The lasers are green and at certain parts are fired from the ground and ceiling.

Other media
The force beams appear in the Mega Man comic book series from Archie Comics.
