and that isn't even the most op use of gravity manipulation you could manipulate and amplify the gravity of the earth to the point that it would crush all life on earth you could do the same with the sun and suck the earth moon and all the other planets into it or you could do it to both the earth and the moon and cancel the gravity of the earth and amplify of the moon and used it like a giant magnet to pull everyone on earth into space any of these would mean the end of the world and you and who ever you decided to let life would the only survivors that is why i tend not to use gravity control as it is one of if not the most op power going and in my hand my guy would basically be a god and that's with just one power lol
