The Trans-Mallux

The Trans-Mallux is a random alliance of groups from a big silver galaxy called the Mallux Galaxy. It's made up of Graeon, Netron, and Hafnion, all of which moved there to get away from the idiots in the Local Group. However, they got found again when Easton Alliance forces arrived in 200415 on an "expeditionary" mission. They joined the United Space Republics because, at some point, everyone does, and they are there today.

Lack of Conflict
Unlike everyone else in the USR, all of whom have fought each other at least once (as well as numerous other undeclared wars), The Trans-Mallux has yet to fight anyone else in the USR, which is confusing, since everyone knows the USR is really just a big fight club for "The Big Six" to duke it out on each other when they don't agree, or when Steven decides to randomly attack SkyClan for no reason *coughcough Second Gostrusum War coughchough*. However, if there is a war, it probably won't be against SkyClan, since The Trans-Mallux and SkyClan are best friends.
