Squid

The squid was commonly known to Humans as a lesser creature, only for consumption by Predators and other creatures, and seen as a lesser variation of the Octopus family. However, in 2028, The Trident Submarine, boasting the world's best Submarine depth capabilities found an unusually large, presumed dead corpse of what appeared to be some kind of Kraken/Giant Squid. Upon trying to retrieve a sample, the creature let out a low-pitched roar which sent earthquakes all across Earth. This caused worldwide panic, as soon after the severe Earthquakes had arrived, large cracks started forming in the ground. These cracks widened greatly, until nuclear bombs were dropped inside to prevent anything from coming out of the cracks. Inevitably, this seemed to anger the beast inside,causing the Catastrophe of 2028.
