Atroxian
The Atroxian is a robotic enemy in the Keen 4 mod Atroxian Realm by Gridlock.
Atroxians are three-eyed flying robots with sharp metal legs, a tough metallic body and electrified wings.
The Atroxian uses it's wings to fly around and chase after Commander Keen, attempting to electrocute him by touch. One blast from Keen's Neural Stunner will temporarily stun the robot causing it to drop to the ground and remain there a few seconds, but if left alone it will take flight again to continue it's attack. After initially stunning it, five more blasts will destroy the robot's wing structure, disabling it's ability to fly. It will then crawl along the ground on it's sharp metal legs, where five more blasts are then needed to fry the robot's circuitry causing it to violently explode leaving only a pile of broken robot parts. Keen will not be harmed by the explosion.
Part of Atroxus' robotic invasion, Atroxians are not native to Planet Krisle and thus can usually be found in areas with Atroxian buildings and machinery. Keen first encounters the Atroxian in the Emerald Canyon, additional locations of these robots are the Atroxian Mines, Port Atrox, the Security Layer, the Atroxian Base, Cargo Transit B, the Kridonea Gateway, Kridonea Ruins, The Catacombs, and The Sky Sanctum.
The in-game help text states: A swarm of these vicious drones has invaded Planet Krisle. You can temporarily stun them to get by, but they can be permanently taken out with greater effort.
The Atroxian is a Blue Bird replacement.
