The primary antagonist/anti-hero from Grappler Baki.
Dubbed "The Strongest Creature on Earth", Yujiro is an incredibly strong and powerful man with "perfect gene", capable of taking on a whole army by his own. He has "defeated" the government around the world and subdued them, thus allows him to do whatever he wished with little to no consequence. He is obsessed with having a "perfect" successor of his bloodline, so he decided to inseminate several women around the world for his heir to be his "worthy" opponent. Hanma Baki is one of his offsprings.
Notorious for his over-the-top showmanship in which he believes his unrivalled strength can solve anything, even brute forcing though an otherwise trivial matters to prove his point.
