The UU has done a lot of conquering, raping, murdering looting amd plundering through out the galaxy. BUT There must be some un-defeated enemies of the UU.
Orks: A pigish, green skinned alien race; Their whole lifestile is war, they are the mist numerous aliens in the known universe. Their whole lives are war. If every Ork warband were to unite no army could defeat them. Just their sheer numbers would overwhelm even the UU. BUT the orks are highly divided, they dont have much order. Like grunts in Halo, if the leader dies they scramble.
Eldar: Another xenos race. They believe they are the "Eldars" OF the galaxy and destroy any intelligent life they come across with their advanced weaponry. Un-defeated; hatred and rivalry brews between them. They can never defeat eachother.
So what do you think? This is for UCA officers to say things like "Remember Istaavan V.." (Istaavan V is were tons of Combine were massacred at a dropsite)
