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

Bio:  
Among Flamefeather's greatest achievements is the fact that he once talked to someone for .12 breems before flying into an unprovoked rage and running to go destroy something.  He's also one of the only Decepticons to have been kicked out of the military academy for being too violent (even Fangry made it through basic training!)
Flamefeather's instructors waived the rest of his training and opted to send him to the front lines immediately.  They hoped that Flamefeather would get destroyed or turn his anger into something more useful, like Autobot destruction.  Luck, more than anything else, has kept him alive since then. His dedication to scrapping Autobots is intense, but his skills are mediocre and unfocused at best.

Weapons & Abilities: In alternate mode Subject's wings can allow flight speeds up to 90 miles per hour.  His flamethrower in this mode can easily engulf an area as large as 100 square yards.  Subject possesses slightly above-average strength.

Weaknesses: 
Few Decepticons are willing to work with the unprofessional Subject, fearing that his incompetence will endanger them.
