The thing about those memories is that there's a sorcerer named Kenjaku who created in different ways multiple children , which Choso, Itadori, and the other 2 came from, so they are brothers by blood, but created like a lab experiment type shi
Gojo thing is his six eyes and limitless technique is a skill that only appears every few hundred years. The curses born react to that energy put into the universe. His abilities and curse energy offsets the balance of the world. He is meant to be and is the strongest sorcerer in the world. The only character that can challenge him is Sukuna and other than him the only ppl who can really kill him is Megumi due to the fact that the six eyes can be challenged by the cursed shadow technique simply because they’re like ying and yang, the last person with six eyes was only killed by a person with cursed shadow and vice versa
so if i recall correctly. with choso. Him and Yuji are biological brothers. both born along with the other 2 as Kenjaku'sm children. Kenjaku hijacked yuji's moms body and then quite literally gave birth to yuji by fucking his father who is the reincarnation of sukunas brother. for some reason i dont remember if it was like a bullshit 6th sense, hallucinations, or even because of blood manipulation. cause choso could only control blood of his own and i think he realized by manipulating yujis blood. but he realized they were brothers. and had that stuipid ass halucination
As far as dragon ball yeah that’s a different power scale, the can easily beat the jujitsu verse and Naruto verse would also win against the jujitsu verse
