Trowa Barton...is basically like Heero accept he hasn't tried to commit suicide yet, he doesn't give people death glares OR threaten to kill them, and he actually says way less than Heero does. He's more damn stoic than Heero Yuy. He's actually got some sort of creepy admiration for Heero. He wants to be like him in the whole 'follow your emotions' thing.
Trowa is basically one huge quiet mystery. In episode Zero, when he was just a baby, it was shown that his patents died during an air raid and that his sister catherine and he were separated. He was found by a group of mercenaries who raised him up like a soldier, by the age of ten, he could pilot a mobile suit and ride a motor cycle. He was on earth but then left for the colonies and become a mechanic. So, he doesn't know who his real family is, what his real name is, where he came from, so if anyone called him, they called him no-name (Nanashi in Japanese). Poor guy. Funny, it sounds the exact same as Duo and Heero...
So, in all, Trowa is just a quiet but deadly soldier. Who loves animals, and the animals love him back. Did I mention that? He can tame lions by sticking his hand in their cages. Yikes. He adopted his name from another man named Trowa Barton, whose father was in charge of operation Meteor,Trowa Barton (the real one) was killed and he having witnessed it agreed to take charge of Operation Meteor from there.
