Fire-breath
Fire-breath is an ability that several Transformers with reptilian beast modes have installed in themselves for combat in their alt modes.
Fiction
Generation 1
The Dinobots had fire-breath included in their alternate modes. Although they all possessed the ability, Grimlock and Slag were the only ones that really employed it. Wheeljack had Grimlock demonstrate his mastery of his fire-breath by adjusting Blaster's volume levels. Later, while practicing on Dinobot Island, Grimlock had Slag practice his "fire stuff" (Grimlock's words) by evaporating a pond. Slag displayed good moves. The local wildlife was not amused. Dinobot Island, Part 1 Later, Slag's fire-breath saved the Dinobots by evaporating the tar pit they had sunken into, but it made him rather tired. Dinobot Island, Part 2
Beast Wars
After becoming a Transmetal 2 dragon, Megatron gained the ability to unleash fire-breath. He was also capable of shooting sub-zero blasts. Megatron likes to keep his enemies on their toes. Yessss... Master Blaster
Animated
Megatron had fire-breath installed in the Dinobots, intending to unleash it against the humans and Autobots. When Isaac Sumdac confronted him about its presence, Megatron claimed that his desire to have a body once more compelled him to experiment by installing the fire-breath as one of several "features". Sumdac bought it hook, line, and sinker. Blast from the Past
