Trying his best to minimize damage to the city and sending the Kaiju back toward Kaiju island. Not wanting Kaiju to be killed by the Kaiju defense force.

A brilliant blue energy core pulses at the center of his chest, surrounded by layered silver and red plating. His narrow waist, elongated arms, broad shoulders, and extraordinarily long legs give him an elegant yet alien silhouette, while the polished metallic surfaces catch the surrounding light like steel. Despite his enormous size of 40 meters, every part of his design feels streamlined and aerodynamic—more like a living alien machine than a suit of metal armor. Although he’s really just a metal suit when he’s Ultraman. Age: 25

Appearance: Professor Hayao Sato is depicted as an elderly, stooped, and shorter-build older man. He has an aging, shorter, and noticeably stooped posture that reflects both his physical toll and his weariness over time Relationship with Kenji: It isn’t simply a “son hates his dad” relationship—they love each other deeply, but years of separation, misunderstanding, and unspoken feelings have made that love difficult to express. they’ve been apart for around twenty years, so their relationship is extremely strained.
