Chinese dragons, of course.
Long, snake-like creatures with two pairs of fearsome claws that's somehow capable of flight.
Captain Karlson's ten dragons were each approximately a hundred meters long, and the untrained minds watching the battle would probably be in shock.
"Just how could ten such massive dragons be formed from a mere mecha?" They would think. "True it's a golden mecha at that, but still, the laws of physics cannot be bent just because it is a golden mecha! The golden mecha is not large enough to provide mass for ten massive dragons!"
But the trained mind would beg to differ.
The laws of physics hadn't been bent at all. They were completely… Well yes. Broken to pieces.
The technological advances relating to the manipulation of energy by that time were such that the laws of physics didn't apply anymore.
E = MC2?
Energy can't be created or destroyed?
Mass must remain constant?
Really?
