The Giant Wasp was an experiment created in The Evolution Accelerator. It was a giant wasp that lived in The Biogenetic Research Centre's tunnels in its own hive.
It's buzzing was frequently heard by Dinah Hunter and Simon James. Lloyd Hunter was stung by the wasp whilst out looking for Dinah and fell into a deep coma. Its sting is equivalent to '100 normal wasp stings' acording to Dinah. It supposedly died when Eve mistakenly started a fire and the hive was filled with thick smoke. It is likely that this Wasp was a queen of a wasp colony.
