So I did a thing.

What they smell like: Steel and citrus. The steel part is pretty obvious, but the citrus actually comes from the soaps used at his favorite car wash. Even when it's been a while, the scent just sort of lingers.

How they sleep (sleeping position, schedule, etc): Steelbreaker's the type of mech who's capable of sleeping in one position the whole night through, generally on his back. He's also a very light sleeper, resulting from his time on the streets before he became a gladiator. As for how long he sleeps, it's generally nothing too long. He actually prefers 

What music they enjoy: He was never a fan of music back on Cybertron (not much of that happened in the gladiator pits, so he was never really exposed to it) but since coming to Earth, he's taken a liking to hard rock. Stuff that he can train to.

How much time they spend getting ready every morning: He may be groggy for a few minutes or so after coming out of recharge, but otherwise it's from the berth to the rec. room for his morning energon.

Their favorite thing to collect: He doesn't see a point in collecting anything. It won't serve him any purpose.

Left or right-handed: Ambidextrous. He picked it up after joining the ranks of gladiators. It wasn't unusual for someone's servo or arm to be ripped off/damaged in some unholy way in the heat of battle, so he felt it necessary to be a capable fighter with both hands, if that were ever to be the case.

Religion (if any): He's never really paid much attention to religion. He supposes Primus exists, but has never expanded on that thought. Unlike most of the Decepticon ranks, he doesn't see Megatron as a living “god”, either. He finds the whole idea to be rather ridiculous, and only mindless fools would ever fall for it.

Favorite sport: Steelbreaker finds humans' martial arts quite interesting. He's actually picked up a move or two from watching their matches.

Favorite touristy thing to do when traveling (museums, local food, sightseeing, etc): Although he may find this or that world vaguely interesting, he's never actually done anything “touristy”. Earth is the first planet that has ever caught his attention like it has, and he often finds himself going on long drives marveling in all of the organic life—not that he would ever admit this. He has a reputation to uphold.

Favorite kind of weather: Since they didn't have weather on Cybertron, he's caught somewhere between hating human weather with all of his spark or being completely fascinated by it. He's come to realize that he enjoys the rain, and the calm it brings him—even though it freaked him out the first time. No joke. He tried to slice at it with his sword until Laserwing explained to him just what rain was.

A weird/obscure fear they have: Before joining the Decepticons, going way back to the days when he was just living on the streets—and even when he became a gladiator—Steelbreaker always feared that he would never find a greater purpose in his life. Basically, that it was going nowhere. The Decepticons gave him purpose and meaning, but that doesn't mean he's never wondered if he made the right decision in joining them.

The carnival/arcade game they always win without fail: He's never tried any, though he'd probably be able to just intimidate the owner of the stand into giving him a prize.
