The mass produced model, the AFC-01I Iota, is typical of the Legioss’ form, specifications and performance. Two variants of the Legioss, also designated by letters from the Greek alphabet, are seen in Genesis Climber Mospeada. The Eta is designed for squad leaders while the Zeta is a high performance variant. Each Legioss contains one Armor-Bike in the chest that the pilot can use in emergency situations. The Eta is manufactured at Mars Base. Because the Eta is designed to be a commander’s machine it has a better computer system than other Legioss.
