Godzilla, because he literally has carried the muto prime on his back (which the prime can manipulate the tectonic plates) he managed to punch mechagodzilla 2021 (WHILE HE WAS TIRED!!!) he was durable enough to tank a meteor that killed 95% of the planet, and he shrugged it off, and his atomic breath drilled through the crust. Meanwhile it’s just a unicorn, it’s honestly just a hydrogen bomb vs coughing baby situation.
