Robo-scorpion

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

- Mobius

Robo-scorpion is a special security robot produced by the Big MT company and serve as robotic guardians for the Big Mountain Research and Development Center. They have a scorpion form with a yellow body, two red pincers, red tail and other parts in green.

Background
The robo-scorpions were created before the Great War by Dr. Mobius and his team in the X-42 robo-warfare facility in Big MT, based on scorpions and powered by a fission battery. They were created for security at the Big Mountain Research and Development Center as robotic guardians with a tail-mounted energy bolt blaster, optical systems allowing anyone in the X-42 robo-warfare facility to see through them with monitors, electrical explosion after their death causing damage to anyone around and public adress systems allowing anyone in the X-42 robo-warfare facility to speak through them. According to Mobius, they can form themselves from floor panels along with any other random parts lying around

Sometime after the Great War, Mobius, after hacking his colleagues and altering their personalities, chronometers, geometers among other things, was disgusted by his actions against his friends and erased some parts of his own memory to ease his conscience, like the knowledge of his pre-War creation, the robo-scorpion. Later, Mobius removed himself to the X-42 robo-warfare facility which renamed the "Forbidden Zone" and began to "re-create" the robo-scorpion, based off now of the radscorpions which had occasionally wandered into Big MT. He add a prefix "b" into his new creations and retained all features of the pre-War model. He also took the control of the previous models of robo-scorpions and they became his personal army, principally used to constantly distract the Thnik Tank.

They are very fast and extremely resistant and the effect of pulse weapons cause less damage to them compared to other robots. The X-42 giant robo-scorpion is a special model adorned with a Saturnite armor plating making it virtually impervious to small arms fire and an improved EMP shield. It also equipped with a powerful tail-atomic laser which it draw the required energy in its internal generator capable of causing severe damage and leaving residual radiation of about 30 rads per second for one second as well as having a blast area of about 3 meters.

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:
 * According to player level.
 * Importance of the area being defended.

Pincer series
The fastest robo-scorpions. They can only use their pincers but track and comes in melee quickly.

Blaster series
These shoot a long-distance electric blue beam from their tail with an average rate of fire and very high damage.

Bomber series
They have the ability to become invisible due to the Stealth Boy integrated in them.

X-42 giant robo-scorpion
Encountered in the Forbidden Zone, the X-42 giant robo-scorpion is a unique robo-scorpion and Dr. Mobius ultimate guardian. It is by far the toughest entity in the entire game, possessing more HP than any other enemy. It is armed with a powerful atomic laser capable of causing severe damage and radiation damage of about 30per second for one second as well as having a blast area of about that of a pulse grenade.
