Come at me bro

wow, bro gaslighted himself

yeah, that was what he thought at first that Sentry and Void and different entity, he was also one of the first superheroes in-universe, as shown the he was best man of reed richards(I think) and reason they gave for him being absent in many events(I think he debuted in 1999 or 2000) is because he realized that sentry and void are the same person, so as long as there is sentry there will be void and then he made world forget existence of sentry and void, so from og it was split personality, maybe you only read issue thought it was another entity

and where does that happen?

I do think it was unnecessary because he could have the same thing without Dimensional State, and seems you dont understand comics dimension power thing(Maphesto is dimension owner and he fought Galactus on equal grounds in own dimension and if you konw how powerful galactus is), so you did you own thing with it which basically ruins system marvel but he is not in, so men
