The Pulse Beam is a weapon employed by Krabs. It is located on the underbelly of the Krab. When activated, a powerful beam of light is emitted, and is believed to cause immediate devirtualization. It has only been seen twice in the series; once in The Chips Are Down, and again when a Krab nearly uses it on X.A.N.A. William in Wreck Room.

Trivia

• Krabs have only been shown to use this ability in the Desert Sector of Lyoko.
• This is the only weapon of X.A.N.A.'s monsters that has yet to hit a Lyoko Warrior.
