Ragnarok

Appearance
Ragnarok is a giant machine with a weapon-like head and a clunky, reptile-like body. It pulses with orange light.

Abilities
Ragnarok's main and most powerful attack is their "destruction beam", which causes combustion on the subatomic level. They also have buzz saws that can protrude from their hands, which can cut through extremely tough things.

Ragnarok's reinforced plating is resistant to all but the most powerful of attacks.

Origins
Ragnarok is an extra-terrestrial machine built for the purpose of destroying civilisations so that their planets can be invaded without any resistance.
