Boobeam Trap (ブービームトラップ Būbīmu Torappu) is the boss of the fourth Wily stage from Mega Man 2, a resistant protection system. The room has five flashing beam guns in the walls that fire simultaneously at intervals, indicating they will fire when they flash faster. They can only be destroyed with the Crash Bomber. The room also has some Destructible Blocks protecting beam guns.


The boss requires strategy to be defeated, as the player can only use seven Crash Bombers, five being to the guns and two of the breakable blocks that are in front of two guns (although an accurate shot can destroy the top-most gun and the left-most wall with one bomb, thus saving a Bomb for later, but this is not recommended for beginners to attempt). The other blocks don't need to be destroyed, being possible to pass by them with Item-1 and accurate jumps. If the player runs out of Crash Bombers, he/she will be unable to defeat the boss until they die, returning to the checkpoint before the first moving platform and being able to refill the weapon's energy before returning to the boss.

If the player is willing to intentionally die at the boss, it's also possible to defeat it using only five Crash Bombs in their second visit. To do this, the player must arrive at the boss room and destroy several blocks, two being at least the left-most wall and bottom-right wall, then get defeated. After which, they would refill their weapon energy on the enemies between the checkpoint and the boss room. Upon entering the boss room again, any walls they destroyed their first time around will still be gone. This does not apply if it was the player's last life and he/she uses a continue.

The Boobeam Trap made an appearance in Issue 12 of the Archie Comics series. Bomb Man helps Mega Man defeat it, but as he used all his bombs, he stayed behind while Mega Man proceeds to confront Dr. Wily.



  • The fight against Boobeam Trap can be made easier by exploiting a glitch from resuming a paused game. By pressing the START button repeatedly, Mega Man will rapidly repeat the teleporting animation which, if possible, can allow shots fired from a Boobeam Trap to pass though him without taking any damage. The best time to execute this trick however is when the Boobeam Traps are flashing or when their projectiles are visible on the screen, otherwise Mega Man will get hit. This glitch will only work on the NES and Legacy Collection versions.
