Devil's Due Transformers vs G.I. Joe continuity
Trailbreaker was among the Transformers discovered on Earth by Cobra, and reworked into a Stinger. The Transformers were eventually freed, and the Autobots fought both their Decepticon enemies and their Cobra oppressors. During the battle, Trailbreaker and several other Autobots located Cobra Commander and tried to capture him, but he was protected by Cobra troops in robotic S.N.A.K.E. suits. Unfortunately, the Autobots underestimated their human opponents, and Trailbreaker was decapitated by Storm Shadow during the battle.
This was apparently not as fatal as it seemed, however, as Trailbreaker was up and fighting again shortly afterwards.
