Data Urek is an artificial character, a Sworn Enemy of Irregular Urek Mazino that was created by the Hidden Floor system after the real Urek finished all stages and quest very quickly to save his data. However, the system failed to copy Urek perfectly because of his power, at that time, exceeded the measurement system and caused systems' malfunctions and errors.
Data Urek appears to be much smaller than his real self. He looks like a child. When he was first seen inside the Glitch Room, he wears black pants and black grey jacket with red thunder motives with yellow strips on both of his shoulders and on the back of the jacket, starting from his neck to the middle of his back. There's also apparently MAZINO's name embroidery in the back of the jacket. He is surrounded by many error messages. He wears a white cap with red visor and silver metal ear piercings. He has a big scar/facial mark on his right eye.
