It's those eerie and enslaving enemies the Labour-otomy Legion! Equipped with their psy-ringes and nonchalant attitude towards their captives, these amphibian super-scientists secrete a solution capable of destroying the willpower of other beings! Here we have some rookie wranglers mind-controlling some of the more dim-witted denizens of the lava-planet Magmarus 14. Magmarus has, straight up, the best magma around. It's bouquet and body simply can't be matched with synthetic magmas so it is highly sought after in the weapons trade for crafting molten-missiles and lava-launchers.
The Psy-ringe is a brutal tool with very little subtlety, you fill it with your own space-frogian secretions and cram it into the cranium of whatever you'd like to control! When the fluids run low then it's best to swap out the Psy-ringe for a fresh batch to make sure your mental enslavement continues on without a hitch.
So beware these brain-bandits and try to wear a really good helmet or something because these grim, cerebral-snaggers mean business!
