This small, yet highly explosive bomb is part of an arsenal of high tech weaponry operated by the cyborg ninja Cyrax. Cyrax's Bomb first appeared along with him in Mortal Kombat 3 and later reappeared as a collectible Relic within the Konquest of Mortal Kombat: Armageddon. Cyrax also uses the bomb as a weapon in the Mortal Kombat (2011) video game.
Cyrax's Bomb also appears in Mortal Kombat X. Cyrax's Bomb is used in the Lin Kuei's Faction Kill Cyber Double Strike, a Kustom Kombat modifier, and a Test Your Might death. Tri-Borg also utilizes Cyrax's Bombs in his Cyrax LK-4D4 Variation.
