And you might be like "Ghidorah doesn't eat a planet whole, he, like, reproduces and they all go on to eat the planet together as a family!," which means you are ignoring that it's unrealistic AND that... HOW THE HECK ARE THEY GOING TO TRAVEL FROM PLANET TO PLANET?? UH, HELLO? EARTH TO WHEREVER YOU ARE? WHEN AN ASTEROID CRASHES INTO A PLANET, IT CAUSES A GIGANTIC EXPLOSION THAT KILLS EVERYTHING (except Godzilla)! YOU CANNOT RECYCLE SOMETHING THAT HAS DISINTEGRATED AND USE IT TO FLY TO THE NEXT PLANET. Once a Ghidorah gets there, they have no choice but to become intelligent lifeforms and build a giant spaceship to travel. What are they gonna do? Build an asteroid from the crust of the planet and then just kinda fly it out into space? News flash: There's this thing called escape velocity, and you have to reach it to leave a planet. Ghidorah has no way of reaching this speed on his own.
