Normally I would say bollocks to CE suits but this one I really wanna see
Testament Gundam A-Rank (Or BS)
Has a Giant claw (Like Shenlong Ver. Ka) which also can turn into an Aile Booster
Has a Virus spread thingy (not sure it it only affects machines or not)
Mercurius (B or A rank, probably A since it sort of rivaled Wing Zero)
I'm actually surprised Mercurius (and Vayaete I guess) weren't in the game when I first started.
Also Shenlong Ver Ka made me sadface so hard (with only one dragon fang I can't make Lobster Gundam EW).. though I wouldn't mind having that and Heavyarms Ver Ka in the game.
