Domon Kasshu was the main protagonist of Mobile Fighter G Gundam.
Domon was seen as brash, impulsive, emotional, and extremely impatient. Domon was very prone to letting his emotions overcome his better judgement, but that was usually leveled off by his partner, Rain's even-keeled personality. Domon was also highly determined to free his father from his frozen imprisonment and find out why Kyoji had stolen the Devil Gundam. Despite the obsession that Domon demonstrated about his mission, he possessed a strong sense of justice, and would usually set aside his own mission when the weak and powerless required his protection. Later on in the series, Domon was more willing to fight for those that he cared about and even opened up to his other friends.
