Monster from Green Hell

The Monster from Green Hell appeared in the 1957 movie of the same name. They are a colony of giant flightless wasps which have been mutated by exposure to cosmic radiation. The area inhabited by them has become known as Green Hell by the natives, due to the fact that all animals flee from it. These monsters started out as ordinary wasps which were sent to space as an experiment conducted by Dr. Quent Brady and Dan Morgan. The shuttle they were in malfunctioned and ended up returning to Earth, where it crashed in the jungles of Gabon, in Western Africa.

Brady later noticed that some of his other test animals had also been affected by cosmic radiation, such as some king crabs having grown twice their original size. This prompted him to deduce that the Green Hell creatures were none other than the wasps from the ill-fated shuttle. The Green Hell creatures are gigantic wasps with proportionally small wings, which, along with their sheer immensity, render them unable to fly. However, they're still extraordinarily dangerous due to their venom and their high reproductive rate, which allows them to multiply fast. Like ordinary wasps, they form colonies and are ruled by a queen.

Furthermore, the wasps exhibit extremely aggressive behavior, as they ambush and kill people for seemingly no reason. Victims have been found to have died from paralysis of the nerve centers, caused by the wasps' venom. Another feature found in this species is that their front legs end in dangerous crab-like chelae, which can be used to grab a human being by the neck.

Explosives are nearly useless against them, suggesting that the exoskeleton is extremely strong in this species. However, they were ultimately killed by a volcano. "Nature has a way of correcting its own mistakes", as Dan Morgan puts it.
