They are made into his weapon fighting style in Mortal Kombat: Deception, and remain that in Unchained and Armageddon. In those three games, every time Baraka starts a round after losing the previous one, if he's laying with his back to the ground, he will lift himself extracting the blades, causing them to be his first fighting style in the next round, instead of Silat.
Erron Black is able to use a detached Tarkatan blade in Mortal Kombat X, exclusively in his Outlaw variation, fashioned from a severed and skeletal Tarkartan arm, making him the first non-Tarkatan character in the series to use one.
In addition, a guest character in Mortal Kombat X, the Alien, has retractable blades in its arms. This is because Xenomorphs take on the DNA traits of whatever species they impregnate; this particular Xenomorph was born from a Tarkatan. Unlike typical Tarkatan Blades, however, the Alien's are segmented.
- Despite only appearing in a non-canon ending in Mortal Kombat (2011 video game) and in concept art for the Refugee Kamp in Mortal Kombat X Female Tarkatan have blades. But unlike their male counterparts, they don't have one long blade from their forearm, they have two smaller blades that come from their hands.
- Prior Mortal Kombat 11, the Tarkatan Blades were originally depicted as looking metallic, while the design featured in 11 have become more organic and bone looking.
