Trailbreaker
Trailbreaker is the name of several fictional characters from the Transformers toy line and animated television series. Due to trademark issues, newer toys of the character are named Trailcutter.
Transformers: Generation 1
Trailbreaker (Glouton in Québec, Tuono in Italy) was portrayed as a light-hearted joker, who often acted a morale booster for his comrades. Deep down, however, he considers himself a liability due to his high fuel consumption. Because of this he has a low sense of self-worth, he often asks to be left out of missions. Despite this, the other Autobots know he is a valuable addition to their ranks.
According to original tech spec notes written by Bob Budiansky, found at Iacon One in 2006, the original name for Trailbreaker was "Guzzle", a name later used by another Autobot character.
Animated series
Trailbreaker was one of the original Autobots aboard the Ark. When it crashed, he was re-activated four million years later and his vehicle was converted to that of a Toyota Hilux. He was a hearty character who would make light of any situation (just as his tech spec portrayed him). His primary feature was his force field which he often used to defend him and his comrades.
