Setsuna F. Seiei is the main protagonist of the story in Gundam 00. He's a Gundam Meister of Celestial Being. In season 1, he pilots GN-001 Gundam Exia and later to GN-0000 00 Gundam in season 2. In the movie, he pilots 00 Qan[T]~-start-25-stop

His name could also be denoted to state his personality. Translated it could mean To obtain the moment.

Setsuna is taciturn, introverted, and righteous against war. He believes there are key disturbances that affect the world from coming together in peace and harmony. He labeled specific people and/or forces as a source of conflict towards the world's path to peace. He has little tolerance for diplomats and politicians, believing that their negotiations only prolong wars and cause more strife (due to personal experience). He's got a vendetta to settle and his past battle experiences stirs old bitter feelings, increasing his combat potential as a beneficial side effect. Though a self proclaimed atheist, he often questions the motivations of God with people and worldly events. He idolizes the Gundams so much that he wants to embody Exia as himself, a Gundam. He's a traditionalist in honor and a martyr for his cause in Celestial Being.

In a letter to Marina Ismail, he revealed more in depth into his feelings and thinking. Setsuna wanted to understand the lesser aspects of humanity. He wanted to know why the world is filled with people with innate dark intentions and inconsiderate of other people's suffering. He wanted to find these answers with his Gundam in hopes to bring mutual understanding and peace.

After a 5 year hiatus, Setsuna has taken an unofficial role as the leader of the Gundam Meisters. He's now able to assert and express his feelings to people without reservation. Setsuna's ideals are still the same, but his recent experiences lead him to believe the importance of self change and the need to fight for a better future. His determination and strong self confidence motivates and inspires people around him. He's more understanding and compromising, but also capable making hard-but necessary-decisions that would lead people to dislike him. He has no problems making life defining decisions for other people when they can't make the choice and would kill if necessary.
