The Mechanist's automatrons are cobbled together from a wide variety of components and junk taken from five different robot models. Junkbots are perhaps the most consistent type in terms of component makeup - usually they are little more than a basic Protectron without any exterior armor and therefore easy to destroy.
All levels of the Junkbot will be present at the Mechanist's lair if the player character is a high enough level.
The basic variant of the junkbot is the weakest of the junkbots and never have any melee or ballistic assorted weapons, but only uses its robot hands.
The cybermech variant is a rarely encountered junkbot and spawns once the player character reaches level 40 . This junkbot has one gamma gun mounted to each arm, used to eliminate enemies from a further distance. As for the body, the head is the one from a tankbot and the junk attached to its shell is painted yellow.
The Quantum junkbot is the strongest and rarest junkbot that can be encountered and only spawns when the player character has reached level 50. Even then this variant does not appear often. The Quantum variant has one laser rifle mounted on each arm and the body of the junkbot is surrounded by an electric field covering the crucial parts of the robot. Like the cybermech variant the body consists of various junk pieces painted yellow.
