Automaton (The Empty Planet)

Automatons were robots used as guards by civilisations in the 21st century.

Technology
The Automatons were tall one eyed robots, they had scanners and laser weapons in the first fingers of their right hand. They spoke a robotic language but could easily pick up the languages of others. (SJA: The Empty Planet)

History
In 2010, two Automatons, one red and one yellow were used to find the heir to an alien throne, who was hidden on Earth.

They removed the whole population safely except Clyde Langer and Rani Chandra, moving the population to a sub-dimension. They chased Clyde and Rani before forming an alliance with them and followed Clyde and Rani to a nature reserve where they found Gavin. The Bio damper protecting Gavin was removed and he was shown the planet he would rule, he left with the robots and the population were returned. (SJA: The Empty Planet)
