Dude screw your haters. .don't give them anymore fuel. Your story is great. So ignore them. Don't let the negative energies they send to you get to you. Take CONSTRUCTIVE CRITICISM on your work not change the story completely negative vibes. Also your Mc is not a reincarnator with complete memories either lol.
Hey author since mc is travelling the multiverse will he go to x men mutant only universe? Then maybe 616 ? I think 616 has many objects that can make him powerful. Also when gorr the god butcher arc comes please make it similar to comics UK where 3 different Thors fought against him to win. You can try adding percy jackson universe cause there is hardly any mention of Greek gods in marvel. Also the ten realm Heaven which has thors sister. Black winter is also a possible enemy. I mean now the mc has considerable strength many routes are open now.
