One of the four main protagonists of Mobile Suit Gundam 00. Pilot of the heavily armored Gundam Virtue, the Seravee Gundam and the Raphael Gundam.
Often depicted as crossdressing. Only tag female-appearing images of Tieria as a genderswap if the artist has said it is a genderswap themselves, or if there is obvious evidence of female gender in the picture. Breasts are not obvious evidence.
Also rivals with Loran Cehack for the title of most epic trap in the Gundam multiverse.
