Kali Sticks are two short poles of bamboo wielded by the Monk in Mortal Kombat Mythologies: Sub-Zero and Lt. Sonya Blade of the U.S. Special Forces in Mortal Kombat: Deadly Alliance and Mortal Kombat: Armageddon, and also wielded by Kobra of the newly rebuilt Black Dragon clan in Mortal Kombat: Deception.
Kali itself is not the name of a weapon but a word for the Filipino martial arts which specialize in fighting with one or two baton-length sticks, using techniques adaptable to empty-hand or edged weapons.
