Kidou Butouden G Gundam  

Mobile Fighter G Gundam, 機動武闘伝Gガンダム

Instead of having a war between the colonies and Earth, a tournament called the Gundam Fight is held. This event takes place every four years by the United Colonies Federation, where each country sends its representative to pilot a Gundam. The goal of the tournament is to determine which nation's Gundam will be granted sovereign rights over all nations until another nation wins in the next Gundam Fight. The series takes place during Future Century (FC) 60 and focuses on Domon Kasshu, a Neo-Japan Gundam Fighter who is participating in the tournament to win as well as fulfill his mission of finding his brother who stole the mysterious Devil Gundam from the government.
