Heh... I've had waaaay too much opportunity to say that in the past year... Yes I am a geek
*inside reference alert!*

Anyway... Natha (the guy at the back) and his four generals... all genetically altered clones of him (hence that they look different)
There we have Magenta Aie, Ochre Une, Platinum Ichi and Ebony Alpha... you should be able to figure out which is which.

A project featuring these guys and their squads is currently in the works... Expect it by September.
