Saw Fist was one of Doctor Inferno's henchmen. Like most other henchmen of Dr. Inferno, Saw Fist is a cyborg. The left side of his face is metal, as is the right side of his body. Saw Fist has a robotic right arm with a chainsaw in place of a hand. His torso piece is also used for Fire-Arm. Dr. Inferno once ordered him to steal an energy crystal from a snowy mountain base. He fought his way through the defenses of the crystal vault and broke open the hatch, then grabbed the crystal and fleed down the snowy slopes in his snowmobile. He was foiled by Agent Chase in his heli-pack, who used a grappling hook to grab the crystal and fly away.
- In Ninjago: Masters of Spinjitzu, when Zane gets half of his robotic face slashed off by The Great Devourer, his face is similar to that of Saw-Fist.
- Since 8631 Mission 1: Jetpack Pursuit was his only appearence; there may be a possibility that Saw Fist died, presumably from falling to his death while being distracted in the pursuit. However since there is no indication of this, Saw Fist's fate remains unknown.
