Godzilla is very scary looking - something between a T-rex and a dragon. He is enormous (estimated at about 20 stories tall) and very threatening, with big sharp teeth and claws, and a huge tail which he waves to lethal effect.
There's a lot of property damage as Godzilla runs through New York City:
A street crumbles as Godzilla comes right up through it.
People are stepped on by his giant paws, or crushed by crumbling buildings (not shown in close-ups).
Many weapons are fired at the giant lizard, but causes more property damage than anything else.
Godzilla blows fire and people are zapped (not shown in detail).
In one scene he gobbles a truck (the driver drops out of it). Helicopters are wrecked, underground subway tunnels are destroyed, a ship and a few small boats are sunk, and a submarine is blown up.
A tidal wave crashes through a pier.
Godzilla gives birth and the junior Godzillas end up chasing and killing several people (the deaths are off camera, but we do hear screaming and sounds of death and destruction).
Most of the baby Godzilla's blown up while inside a building.
A man is killed after his helicopter is eaten by Godzilla, while in it. (nothing graphic is shown)
