Dr. Genus

Shit... Those stupid apes! Acting like I'm weird! "Dangerous ideas"? Don't give me that crap! Do they honestly believe that humans came this far by avoiding all that seems dangerous?

Dr. I. Genus (ジーナス博士, Jīnasu Hakase) is a world renowned scientist and the founder and former head of the now defunct organization, the House of Evolution.

He is the first person to deduct the origin of Saitama's limitless and god-like power through his theory of limiter in living being.

Appearance
Genus, despite being considerably old, has the appearance of a young man due to his tampering with his own genetics. At his young age, he has sharp features with blue eyes and short black hair, parted on his right side. He wears glasses and a suit with a lab coat.

Personality
Dr. Genus is gifted with a vast intellect, but due to that at a young age he became disillusioned by the rest of society. He feels that society needs to evolve and that if it can't do so by itself he must make it evolve. He has a change of heart after witnessing Saitama's fight with Carnage Kabuto, beginning to think that he is the one who must change.

History
From an early age Dr. Genus doubted the claim that humans have unlimited potential, he considered the people around him to be primitive and found it painful to live among them. At age fifteen, he decided that he would make humanity evolve further and create a world in which he would be able to live. Over the next few years he used his immense intelligence and made various contributions to the world. However, despite all the praise he received for his intellect, no one would approve of his ideas to artificially evolve human beings through man-made mutations. He thus decided to carry out his plans by himself. His plans finally started bearing fruit after he turned seventy, when he managed to return his body to its previous youthful state. After that he started creating clones of himself in large numbers and together with the clones conducted countless experiments on animals and then switched his attention to humans. He named their laboratory "House of Evolution" and through experimentation created a large number of new species there.

House of Evolution Arc
Dr. Genus first appeared, when his monster Mosquito Girl was killed by Saitama, casually noting that Mosquito Girl without blood was just an insect with wings. However the clone corrects him, stating that Mosquito Girl was killed after consuming a large amount of blood, moreover in a single hit. Genus momentarily wonders why Saitama is naked before declaring his intention to examine Saitama's body for experimentation, sending Kamakyuri, Frog Man, Slugerous, Ground Dragon, Armored Gorilla, and Beast King to "invite" Saitama to the House of Evolution. Much to his frustration, the mysterious beings he had sent were wiped out, forcing him to make plans to release Carnage Kabuto as a last resort.

The original Genus appears in front of Carnage Kabuto after the test subject had killed a number of his clones, proposing he bring in Saitama for his experiments. Carnage Kabuto takes Genus along roughly, and after Genus identifies Saitama and Carnage Kabuto challenges him, Genus is seen nursing his injuries while witnessing the battle between Carnage Kabuto and Saitama from afar. Like Carnage Kabuto, Genus is taken by surprise at Saitama's explanation of his immense strength. Upon witnessing Carnage Kabuto enter Carnage Mode, Genus loses all hope for a moment and is completely taken aback when Saitama obliterates Carnage Kabuto with a single punch. Genus, apparently finally understanding the meaning of Saitama's words, then abandons his evolutionary endeavors and concludes that he himself is the one who has to change.

Alien Conquerors Arc
In the anime, Dr. Genus and the Armored Gorilla are working on their new Takoyaki shop when they see the news about the attack on A-City by the Dark Matter Thieves.

Monster Association Arc
After much trial and effort, Zombieman is able to track down the former mad doctor and his cyborg aid and confronts them about his suspicions that they are the god level threat mentioned in Shibabawa's prophecy. However, when Zombieman does confront them he instead learns that Dr. Genus had discarded the very idea of the House of Evolution. He now agrees with Saitama's philosophy that what makes humans strong is that they can change themselves, without the need for monsterization, cybernetics, genetic engineering or drug regimens. Genus goes on to detail his theory about Saitama's power: In order to function, every living thing needs to have limitations placed on themselves, or else the immense power of a limitless being would drive them insane. In Saitama's case, aside from losing all of his hair, he also lost his will to live and experienced an alienation from his surroundings. As for why he's opening a Takoyaki shop, he's applied his research in the House of Evolution to mass producing octopus cheaply.

Fall of Hero Association
After Garou's defeat, Zombieman meets with Genus to discuss about his confirmation about Saitama breaking his limiter to gain god-like power. Zombieman requests Genus to remove his limiter, like what Saitama did to himself. However, Genus told Zombieman that he will show Zombieman something interesting in the basement of his shop.

Abilities and Powers
His endurance and fighting ability is considerably average, but he managed to survive Carnage Kabuto's abuse and even managed to stand and walk while suffering from intense physical pain.

Trivia

 * In the anime, his introductory montage in episode three depicts a moment where his eyes momentarily glow green. In a similar anime-only moment in episode one, Saitama's eyes glowed orange after defeating Crabrante. Saitama and Dr. Genus are the only characters shown to exhibit this effect so far, so it's unknown what it represents.
 * Evolution_Cup.png has a set of tea cups with the picture of human evolution in his house, which reflects his long and lifetime works and intention.
 * Genus can be considered to be one of the best scientists in the series along with Bofoi and Dr. Kuseno.
