Height 189cm (6'2") Hyoga is a survivor who was revived by Tsukasa Shishio. Initially, he was an elite member of the Tsukasa Empire since he was depetrified by Tsukasa.

Spoiler

He ultimately betrays Tsukasa by attempting to take over his leadership and threatens Senku into joining, only to be defeated by the duo in the decisive battle for the Kingdom of Science. When the situation calls for it, he is depetrified once again and summoned to battle - now as a begrudging ally of the Kingdom of Science with a similar but slightly mellowed goal in mind. Since his third depetrification, Hyoga's goals are unknown.

Hyoga has an easy going attitude towards everything. Even in situation that do not work in his favour, he still remains calm. While he claims to share the same values as Tsukasa when it comes to only reviving the young and creating a community where no one takes from others, Hyoga himself is an elitist who believes in social darwinism. He categorizes humans as either enlightened (or strong) and unenlightened (or weak). He believes that the "brainless incompetent masses" should not be allowed to live and that only those who excel should be allowed to live. While he does follow a form of social darwinism, he does not believe it is only the physically strong who should survive, as he wanted Senku to join him in his endeavors and become the strongest duo, indicating he respected Senku's intelligence and understood his capabilities. He is very manipulative and cunning, seems to be observant, and can often be cruel, merciless, and uncaring. He tends to refer to things as being done "properly" or not.
