I think an mc with just the gamer is Op enough. Demon king bloodline which lets him match everyone without the gamer and then on top of that give him knowledge from another timeline in which he gained power and most importantly knowledge is a little too much. I will try a couple of more chapters but I kinda hate revenge timeline so I am not hopeful.
I don't understand anything at all at this point. Is the MC OP/Powerful or is he weak? Because at this point he is loosing to fking Thanos (who without the Infinity Guantlet is pretty weak comparitivly). Even Darkseid could be compared to SuperMan, who although strong, is not the benchmark for OP. So if MC can't even handle this level of opponent, this he seems pretty weak to me.
