The Vespiform
Vespiforms were a species of insectoids which resembled oversized wasps. Adults were about three metres tall. They were powerful creatures, with large stingers which could be regrown within hours of use.
Vespiforms could change into other species. The transformations were accompanied by a glowing, purple-pink haze and left behind morphic residue.
When in another form, Vespiforms were genetically compatible with the mimicked species. They could interbreed with members of any other species. Any offspring would be locked in one form until put under stress, when they would turn into their Vespiform shape. (TV: The Unicorn and the Wasp)read more
