Technology & Combat Characteristics
Bigro is one of the earliest space-use MA made into practical level made by Principality of Zeon during the One Year War. Its structure was simple, combining a wedge-shaped body with two claw arms. The secret was in its massive size, which allowed it to carry large equipment that set it apart from MS, including a large mega particle cannon, as well as super-high-output generators and thrusters. In particular, the generator output was more than 18 times that of the Zaku II (Thunderbolt Ver.), allowing it to fully operate the large mega particle cannon and high-thrust thrusters. While it was not as versatile as an Mobile Suit (MS), its firepower and mobility in space can overwhelmed any MS. It excels at hit-and-run tactics that make the most of its large firepower and thrust, and is said to have destroyed many Earth Federation ships and MS. Several units, including its variants, were deployed in the Battle A Baoa Qu, and a unit believed to be a later model was engaged in combat with Bianca Carlyle's GM.
History
