The Lombax Solider concept (not by me)
The Lombax Soliders are 3 lombaxes that carry around heavy sniper rifle/machine guns. They were stranded on an asteroid as kids after Tacyon fought and almost wiped out the lombax population. Blade found them while travling the galaxy. He then trained them to be soliders. They are the 6th, 7th and 8th lombaxes introduced in the series, the other 5 being Ratchet, Angela Cross, Alister Azimuth, Amber, and Blade. They act like Clone/Stormtroopers from Star Wars, and always refers to the other lombaxes as "Sir", "Sarge", "Commander", etc.
