Although Godzilla isn't larger then a universe, His power level surpasses even the box. he needs no introduction. He is the king of the monsters, calling this beast powerful is a HUGE understatement. He has once even split uqraek fibers into protoverse's. he exists in 3 to 100 dimensions.

The largest creature possible on an earth sized planet. He is also very intellegent. Even able to outsmart humans!

He also can survive intense pressure. For example, he lived in the Mariana Trench for millions of years before being awakened by nuclear testing.

He has died in the past but like a phoenix is always reborn. He also has the ability to breathe nuclear breath which can vaporize even the toughest of metals. In comics he has shown box-level power. Even slaying something equal to The Primordial in power! He truly is the king of monsters.

He can even regenerate from a single UQRAEK FIBER.

And he is in the spinosaurus canon I made.
