First, I would like to say that the protagonist is completely unbalanced. He is not evil; he is more chaotic neutral. He does not care about anything as long as it helps him achieve his goals. His personality will improve to become more "chaotic good" when he feels more secure about himself and his strength.
Second, the protagonist's mutation gives him a supercomputer in his head. It is very similar to Sage's mutation, but his is Omega level and more comprehensive than it seems. His level of intellect is very similar to Superman's. He stores and processes data almost instantaneously; you can call this mutation a Kryptonian brain. Of course, it is not that simple. Due to the mutant factor, his brain works like the Orks' brains from Warhammer, that is, believe hard enough and it can happen. You can call this a small-scale reality distortion; the MC does not know this final detail.
Third, he has the Eyes of God from the anime Kekai Sensen, highly recommended for those who have not seen it. Because of these eyes, the protagonist's mutation evolved into something very abnormal. Before, he only had an above-average delta-level intelligence, but because of the eyes, his mutation evolved to Omega level and turned him into a living supercomputer.
Fourth, the protagonist's intelligence is relative, meaning it depends a lot on me, and I am dumb as a rock, therefore do not expect much. If he makes silly mistakes, it is my fault. Just take this novel lightly and do not think too much about it. I am not trying to create something serious; I am just trying to create something to have fun. The evidence of this fact is the power of the ORK from Warhammer that the MC has.
Technically speaking, if he believes strongly enough, he can build a spaceship with just a hammer. Therefore, do not expect much scientific logic from his projects, just accept it. Also do not expect a protagonist who acts much like a scientist; he is very reckless! After all, he is an ORK!
Fifth, this is a harem, look at the tags, friends. So to my No Harem companions, goodbye, I will miss you. For those who stay, I will explain: due to his mutation, the MC hates inefficiency, and entering a relationship with a Marvel woman is just endless trouble. After all, this universe is a mix of the comics, animation, and the movies, meaning the women have more of the comics' personalities. Personalities that sleep with everyone, change partners like changing underwear, etc. The Hulk woman in this universe already has more than 100 ex-boyfriends, something that is canonical in the comics.
Therefore, the MC does not want to DEAL with this inefficient nonsense. Not to mention that modern girls will not accept a Harem; even someone as open as She-Hulk does not accept a Harem. That is the biggest reason he follows this path. After all, it is a modern world; something like a Harem is impractical. To avoid dealing with "unnecessary drama" and possible betrayals because of his technology, he prefers to create his own wives for himself, who will be inspired by anime from his past life.
In total I am planning around 7 initial women; some may be added in the future depending on whether the MC needs them or not. Each one will have a function in his group, efficiency above all after all. They will be his wives, but also his comrades-in-arms and leaders of his organization.
MC's companions.
Artoria Walker: Artoria Lancer appearance, the Queen and vice commander of the group. Initially, she has Jean's genes, Emma Frost's genes, the super soldier serum, and Sage's genes. She is the MC's strongest telepath.
Other's to come.
