Trowa Barton is a character first introduced in the TV anime Mobile Suit Gundam Wing.

The most experienced soldier of the Gundam pilots, and the only one born on Earth, Trowa is a quiet but determined person. Patient and calm, he will analyze a situation before acting. He hides his feelings well behind an impassive mask. Despite his stoic demeanor, Trowa developed a close friendship with Quatre Raberba Winner. Symbolically, Trowa is often affiliated with masks; not only because of his neutrality and his talent for infiltrating enemy ranks, but also because of his job as a circus clown—a job where he wears a costume and painted mask. Trowa is also shown to have a strong connection with animals, evidenced by when he first joined the circus. On the battlefield, Trowa attacks his enemies with utter ruthlessness and deadly accuracy.

Trowa has a great deal of emotional control, allowing him to calmly approach any situation without being emotionally compromised. He's naturally gifted in acrobatics; he has a good ability to balance his body and applies it to his Gundam in combat. Trowa is also gifted in calming animals and even befriending them as he's able to tame a lion with ease.
