[@vietmyke] Yes Zeon!! Alright, I loved Garma, which is kinda weird for me cause he's so... Almost prissy. But I think being on the side more often labeled as bad would be very fun. There is also the option of introducing a third group (not like celestial being) that have formed to protect their own colony during all of the war. 

As for the gundams, I'm thinking a smaller number could actually use them. Like three people who have gundams, but also have slightly personalized suits for the others.
