Destructor

The Destructor is a alien robot that is found within the Insaniquarium Universe. It is one of the only non-organic aliens that is found in the game, yet has the game motive as the other aliens to destroy all fish.

The first destructor was invented by a scientist on Earth, created for his nephew. His nephew though was sadistic towards his pets, which was what gave the first Destructor inspiration to act the same way.
