Transformers: Animated is a pretty good show. I enjoy what episodes I get to see. This is Foxtrot Sirius. He's actually based off of my Ford Taurus in his name (I call my car Foxtrot on occasion) and the scar down his left eye (my car has a gash in the bumper under the headlight).

Foxtrot Sirius, or just Foxtrot, is an explosives expert. Not part of any particular faction, he prefers the Autobots for their better attitudes, but has been persuaded to the Decepticons by their promises of helping him extend his explosives research. He's a maniac for anything that goes boom and has been known to point out how a BOOM could be bigger. His main armament is known as a Micron-Bomb, a fuse-lit explosive of his own design that produces a large explosion upon detonation, which scatters 'microns' that can burn through most armor. The spear he carries in robot mode can be used to light the fuses from a distance. Note that he's not smoking a cigarette. It's actually a cybertronian equivalent that formed from low-grade scrap. His eyes contain scanners made for absorbing and scanning explosives from a distance to better understand them.
