Profile, Abilities and Weaknesses description taken from The Transformers: More Than Meets The Eye, comic series published by Dreamwave Comics in 2003.

Bio:  
Cindersaur is only barely conscious of what's going on around him. It is suspected that this pyromaniac Decepticon permanently damaged his cerebro-circuitry through smoke inhalation.  Cindersaur burns everything in his path to the ground for fun, and also because he's too stupid to find his way back home without an obvious path of destruction to follow.  He's released on the field to sow terror and confusion and he's surprisingly capable at his job.

Weapons/Abilities: 
Subject is impervious to most heat-based attacks.  In creature mode, subject has a fusion-powered flame thrower mounted in mouth.  He can use this weapon with extreme accuracy, making anything from a thin, concentrated stream of fire to a wide spray.  In robot mode, he uses a less powerful flame-thrower rifle.

Weaknesses: 
Subject is a dangerous combination of pyromania, stupidity and mental instability.
