Meitzer Ronah

Meitzer Ronah is the backer of the Crossbone Vanguard and the founder and ruler of Cosmo Babylonia. He is the secondary antagonist of Mobile Suit Gundam F91. Despite being the one behind Cosmo Babylonia and the Crossbone Vanguard, his son-in-law Carozzo "Iron Mask" Ronah is the true threat.

History
Meitzer Ronah was a businessman who sought to create a nation that adhered to the principles of "cosmo aristocracy". To this end, Meitzer backed the foundation of the Crossbone Vanguard, led by his son-in-law Carozzo Ronah better known as "Iron Mask" in order to use them to conquer the Frontier colonies so he could use them as the basis for his new nation.

The Crossbone Vanguard's first move was invade and conquer Frontier IV. They also kidnapped Cecily Fairchild who in truth was Berah Ronah, the granddaughter of Meitzer who had fled the Ronah family along with her mother due to Meitzer's dogmatic commitment to his ideology. After her capture, Cecily was pressured by Meitzer into becoming the figurehead for Cosmo Babylonia's conquest.

However, Meitzer's dreams would fail to be fully realized once the Crossbone Vanguard was defeated in battle at Frontier I and his son-in-law Iron Mask was defeated and killed by Seabook Arno in the F91 Gundam.
