Harpy

A Harpy is a flying Skyswarm bioform of Tyranid. Larger and more powerful than their closely-related bioform the Gargoyle, Harpies are roughly comparable to an aerial Trygon. Harpies have a sinuous, snakelike body, with a broad head covered in organic armor. A pair of very large, leathery wings give them flight, and enable them to out-manoeuvre many aircraft. The Magos Biologis of the Adeptus Mechanicus have argued whether Harpies and Trygons are closely related bio-forms or separate genuses in their own right. However, few comparative studies have been made, and to date, phylogenetic categorization remains highly speculative.
