First person: I (old man) / I (formal) Second person: you (blunt) / you (derogatory) / [Name without honorifics] Height: Approx. 187cm A man who appeared in the Paleolithic era, claiming to be an immortal Spirit King. His true identity is a time criminal from the 23rd century. He plotted to build his own empire by developing a subspace destruction device to isolate that era from the timeline. A Homotherium sits beside his throne. He commands the Kurayami tribe and Tsuchidama as his subordinates. He carries a spear-shaped device that can dismantle any machine and can fire dismantling beams from his fingers. He is cold-blooded and cruel, ruthlessly dissolving his subordinate Tsuchidama for failing. He wears a terrifying mask, but his true face is that of a sharp-featured middle-aged man. He wears ominous, robe-like clothing. Ultimately, his ambitions were crushed by Doraemon and his friends in cooperation with Kukuru. Notably, his 23rd-century machinery—his last resort—was destroyed by Kukuru, resulting in his total defeat. He was subsequently arrested by the arriving Time Patrol, and his base was detonated to ensure it left no trace in history.
