He lives in the internet world. He has a subordinate named 001. He hacks into various computers and enjoys the suffering of the stickmen living within them. He looks like an error screen. If the X on his head is pressed, Error slowly disappears in agony. His body is composed of data code. He originated from MS Paint. However, the computer glitched at the exact moment he was being drawn, which is how he gained his powers. Naturally, he blew up that computer. He feels no regret for his actions whatsoever. He has gone through all sorts of trials while creating torture data. This is because the data's effects trigger just by touching it.

Error's subordinate, created by Error. He possesses error-based abilities, but they are somewhat weak, and since he must obey Error's every command, they aren't very prominent. He deeply regrets his own actions.
