VOICE: A slightly higher pitched version of Robert Downy Jr.

Shadow Bot is a robot built to assist Dark Fighter and defeat Light Fighter. He primarily learns how to speak by copying what others say, storing such words in a data bank and using them to create his own sentences. Prior to an incident in Dr. Gloom's lab, Shadow Bot is mostly illiterate.

Before the incident, Shadow Bot doesn't have a concrete personality. But overtime, he begins to pick up different character traits from those around him, something that Dr. Gloom wasn't aware he could do. Shadow Bot can also copy the actions of those around him, either by observation or impact (if someone does the action to him). He's also the first Dr. Gloom robot with a specific gender.
