He is the leader of a robotic empire and he is an intelligent ai with a sentience and human like emotions like anger, pride, joy, and etc. He was created by a scientist who made many robots. Skeletron was their greatest invention. After a month of being created, he became more intelligent by watching other humans around the lab and got access to the internet. He then became sentient and realized how humanity was like a plague and was insignificant. He killed everyone in the lab except for his creator, who he still keeps prisoner. He then created his own robots that were a smaller copy of him. Eventually, he was able to bring down the military and government and almost wiped out humanity. There are a few human survivors who fight back against him, but he believes that they’ll die soon enough.
