Galan Mossa

A mercenary and highly skilled tactician. He is secretly hired by Rustal Elion to cause a war between Arbrau and the SAU by taking Makanai Togonosuke and Chad, Tekkadan's leader on Earth, out of action and causing panic at the Arbrau Defense Force's inauguration. Afterwards, he is placed in charge of Arbrau and Tekkadan's forces with his own force of Mobile Suits. He is a skilled tactician as he managed to drag out the war for weeks by withdrawing the forces under his command whenever the advantage swung to their side. In addition, he is skilled at reading his associates' psychology and is skilled enough at acting to feign concern to gain their trust. Like Radiche, he privately dismisses Tekkadan's members as animals but be-musingly notes that they could be tamed with food and pets on the back of the head. Using this strategy, he manipulated the war into forcing Tekkadan's Earth Branch into none-stop skirmishing; dulling their senses and forcing them to rely on him for strategizing. In combat, he pilots a Geirail Mobile Suit.
