Sawtooth and his comrade Bolar were stationed at a Predacon base under the interrogator Steelgrave. When the Maximal prisoner Wing Saber made her escape from the facility, she created a diversion by provoking a fight between Sawtooth and Bolar and their commander. Steelgrave survived the fight; whether or not Sawtooth did is unknown. The Razor's Edge
Sawtooth's name and physical description are based on those of Sawtooth, a member of the evil Destructors in the 1980s Tomy toyline Starriors. He was not given a name in the story itself, but author Ben Yee confirms his identity.
