Robo-scorpion

"Intruder, you will not escape the eyes of my robo-scorpions! Or their pincers!"

- Mobius

Robo-scorpion is a type of robot found only in the Big MT in 2281.

Background
The robo-scorpions are robots created by Dr. Mobius in Big MT, based on the radscorpions and powered by a fission battery. They were created for security at the facility as robotic guardians at first, but after the exile of Mobius, they became his personal army. They have a yellow body with red pincers, red tail and some other parts are green. According to Mobius, they can form themselves from floor panels along with any other random parts lying around. They are very fast and extremely resistant, and the effect of pulse weapons don't cause as much damage on them as other robots. After their death, they cause an electrical explosion that can deal damage to anyone around.

Variants
Robo-scorpions appear in Mk 1, 2, 3, 3b, 4, 5, 5b, and come in stinger, blaster, and bomber variants as well as different sizes relative to their Mark. Their appearance in the game may depend on the following:
