A massive project of lineups in the making for the past year, provided by  hambor12 !

These feature a major neutral faction, the Ascendant Kingdom of the Rol'wah Kha, from the left to right:

Rol'wah Kha - They were not energy beings from the beginning, taking on new forms as a last ditch effort to guard something in the center of the milky way galaxy. They are extremely cunning and intelligent.

Landers - Nanomachines that can take multiple forms, they are walking super computers that assist in the Kingdom's daily activities.

Dogun - Biological weapons of war, they are the military might of the Kingdom. Their eyes are hidden underneath a special layer of skin, bioengineered from a special slug that lives near the galactic center.
