My Perfect Isekai

In a world ruined by countless years of battle, the king of the monsters uses the last of his strength to defeat his greatest enemy. But it is all for naught in the end, as the monster destroys everything, including Godzilla, in one final hail mary maneuver, destroying itself and everything else. Yet despite that, Godzilla's soul still persisted in another world. A world where he would make sure that humanity would never be able to abuse their power again, by any means necessary.
