Just the commandos of the Sirrushian Dragons. I really don't like putting up just single minifigs, but I kinda have no choice here as I took him apart a long time ago.
These guys are trained to handle most battlefields, and can usually be found relentlessly pummeling enemy troops into submission or worse. Several, if not all of them are more than a little bloodthirsty, and it's rumored that their captain finds joy only when fighting powerful foes. Their suits contain shielding and life-support systems, plus it administers anti-toxins and painkillers when necessary. The suit also gives a warning when radiation levels are particularly high, and has an oxygen tank with a built in flashlight. Hidden compartments contain a month's supply of dehydrated rations.
