Ding is a retired reconnaissance soldier.
His life was normal at first, he went through training. He then became a recon soldier for the Irken Empire, and was sent to earth to discover what little significant things the humans were hiding. He succeeded, however, he returned with a serious psychological disorder, explained in his behavior section. During an interrogation, Ding jabbed his PAK with an active wire, somewhat restoring his ability to do basic functions. However, he completely destroyed the ability to distinguish between a living thing and a slice of bread, so he electrocuted his interrogator with the wire, which effectively killed him, ate him whole and then regurgitated him. He then re-routed his suit so that the electricity would discharge at his hands rather than his feet. He burst out of his containment cell, charred, ate, and regurgitated everyone in the building, and then escaped.
Ding's behavior can be best described as he thinks he is a toaster with the ability to speak. He constantly gorges on bread (or whoever he kills) and regurgitates it, and plugs active electrical wires directly onto himself without thinking that he could get electrocuted. It was in this manner that he nearly fried his PAK immediately after returning from his mission, encouraging others to make him a grounding suit. Often times, he is completely sane, other times, he is terrifying.
Ding is an Irken, average height, with dusty blue eyes. He wears what can be described as a "grounding suit", which is a tinfoil-ish suit with boots that automatically glue themselves to the nearest solid surface whenever Ding tries to "power himself".
