Void Getting Beat Up

Boom!

The tree Grey and his friends used in going underground was exploded into smithereens as the huge body of the dragon came through it.

Roar!

An earth-shattering roar came out of its mouth spreading in all directions as the hole that it came out from was sealed in ice.

The dragon was an Ice Dragon. Unlike humans, there's a distinct difference between an Ice Dragon and a Water Dragon.
