Review Detail of Fellow_Daiost in Grandpa Universe In Multiverse [COMPLETE]

Incredible novel! Looking forward to when he is going to overpowered worlds, like DC or Marvel. And if you send him there you could even explore the universe and other worlds to develop better the story and until now don't see no one going to space in a DC and Marvel fic, that of course if the person is not already in space, but even if he is, they all go to earth.
