Godzilla

Godzilla is a fictional character in that first appeared in "Godzilla".

Powers
Physical Strength: Godzilla has been known to pick up other Kaiju (Sometimes by the tail if they have one) into the air.

Atomic Breath: Godzilla can fire out of his mouth a beam of energy. Godzilla had used this to make destruction upon Tokyo, Japan.

Amphibiousness: Though technically a reptile and not an amphibian, Godzilla has an amphibious lifestyle. He spends half of his life in water and the other on land. He is as adept a fighter underwater as he is on land. Capable of marching on the seafloor or swimming by undulating his tail like a crocodile, Godzilla is displayed as being able to breathe underwater, occasionally hibernating in the ocean depths between movies, and being submerged apparently does not impede his atomic ray. He engages opponents in the sea on multiple occasions, beneath or on the surface of the waves.

In Legendary Pictures' Godzilla, Godzilla now possesses gills/amphibious lungs so he can stay underwater indefinitely, but he closes them when he's on land and uses his lungs. These gills appear to be weak points, as Godzilla reacts whenever he is struck in the gills by artillery fire or strikes from the MUTOs' claws. In Godzilla: King of the Monsters, he's shown to be an incredibly powerful combatant in the water, ripping off King Ghidorah's left head and most likely would've won if the Oxygen Destroyer not interfered.

In Shin Godzilla, Godzilla began as a prehistoric sea creature that fed on nuclear waste on the sea floor, causing it to evolve rapidly. When Godzilla finally came onto land, he possessed gills on the sides of his neck. When Godzilla initially came ashore, these gills leaked red fluid, possibly his blood. The gills closed and decreased in size as Godzilla grew and evolved further, but are still present and could be seen glowing whenever he charges his atomic breath.
