Primus

Primus is said to be the creator of the Universe, meaning that he is also the original creator of Gensokyo and all of its regions. Primus and Orion co-exist, meaning that Primus must exist in every single known universe to exist. Primus killed universe 1 Saikou, and has given Saikou only 3 more years to live- two more stories, in our time. This means that there will be a new main character, and many fans have raided 4chan to spread the news. Sam Wilson, who uses the character Misaka, has hinted towards this, saying that "The forgotten will come back, and the Son of Primus will return." We belivee that Hot Rod, Nathan's earth son, and Primus' galactic son, will rise to become the main character of the entire series. His transition to Rodimus will appear in the next arc after Saikou AND Old Tetsuo die permanently. Primus has no liking with science, which is why he and Nathan never agree on who is the true father of Hot Rod, Primus claiming that "Hot Rod was born, and you tried to change that." This leads fans to belivee that Nathan attempted to change Hot Rod's DNA, so he could be less like his true father, and more like himself, more beast-like. Primus and Remilia Scarlet are said to be together by fans, who have seen multiple screenshots and photos of them, including official artwork by Sam Wilson.
