Setsuna F. Seiei

Setsuna F. Seiei (刹那・F・セイエイ - Setsuna Efu Seiei) is the main protagonist of the story in Mobile Suit Gundam 00. He is a Gundam Meister of the paramilitary organization Celestial Being and is humanity's first Innovator. In season 1, he pilots GN-001 Gundam Exia and he pilots GN-0000 00 Gundam and co-pilots its upgrade, the GN-0000+GNR-010 00 Raiser with Saji Crossroad in season 2. He pilots the GNT-0000 00 Qan[T] in Mobile Suit Gundam 00 The Movie -A wakening of the Trailblazer.

Personality & Character

Setsuna is taciturn, introverted, and wholeheartedly against war. He believes there are key disturbances that prevent the world from coming together in peace and harmony. He has 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 stir up old bitter feelings, increasing his combat potential as a beneficial side effect. 

After Setsuna became an Innovator, he once again became stoic and closed his heart to people once again. The crew members had trouble dealing with his inconsiderate nature, but they did their best to adjust to him because they believe he'll eventually turn around. Sumeragi reasoned it was probably because he had become different from the others among the crew and was confused with his Innovator abilities. After the ELS Conflict, Setsuna had since become a friendlier and warm person in his eternal mission to promote mutual understanding. 

Skills & Capabilities

Setsuna is skilled in many ways of war and fighting. Trained by Ali al-Saachez at a young age, Setsuna already knew how to work with a wide range of firearms, close-quarter-combat, use of explosives, infiltration, and other areas of guerrilla warfare by the age of 10. As CB's Gundam Meister, he uses his former combat training in his KPSA days to reflect Exia's combat style. He's been trained by CB to know some MS technical skills to maintain and repair his Gundam. 

His 4 year hiatus (AD 2312 - Season 2) with Celestial Being didn't dull his MS piloting skills at all, his MS combat capabilities were refined as his MS CQC skills and aiming showed great improvement. Due to the power of 00 Gundam's concentrated GN particles with Trans-Am Raiser, Setsuna's brain has been gradually enhanced to utilize quantum brainwaves. He's able to sense quantum brainwaves (QBWs) near him and track users of QBWs. Eventually, he naturally evolves into humanity's first true/genuine Innovator. 

Setsuna's Innovator capabilities aren't completely defined as he's the first naturally evolved Innovator. It has yet to be revealed if he can communicate with Veda or Celestial Being technology like the Innovades can. He can anticipate movements and actions of his opponents and sense impending danger from far distances. As an Innovator, he has heightened reflexes, a longer lifespan than normal humans, and can communicate his thoughts via quantum brainwaves. 

After Setsuna joined the ELS, his body is not entirely human. The ELS reformed his body based on their bio-technology, forever retaining his youthful appearance with a metallic shine. It can be inferred that Setsuna became a hybrid of an Innovator and an ELS.
