The Pulse Blade is a newer version of the Sabre of Light, Cyrax's high-tech cyborg weapon from Mortal Kombat Gold.

Cyrax uses a blue Pulse Blade in Mortal Kombat: Deadly Alliance and a green one in Armageddon.

Sektor also uses a Pulse Blade in Mortal Kombat: Tournament Edition, as he is a palette swap of Cyrax in that game, and wields two red Pulse Blades in Mortal Kombat: Armageddon.

Takeda Takahashi uses two orange Pulse Blades in Mortal Kombat X in his Ronin variation. His Pulse Blades can also be used as mines.


  • Strangely enough, in Armageddon, Cyrax is able to pull his Pulse Blade out during a Fatality, while Sektor can't pull out his.
  • Cyrax used his Pulse Blade against Havik in the opening of Mortal Kombat: Armageddon.
  • The single Pulse Blade that Cyrax wields has the same attacks and animations as Shang Tsung's Straight Sword.
  • In Deadly Alliance, Cyrax’s Pulse Blade had a blue colored blade. In Armageddon, the blade was changed to green. This is likely a homage to the Star Wars films, where the main character Luke Skywalker has a blue lightsaber and then, in a later film, constructs a green one.
