The Hydra series mechs were designed to face multiple smaller opponents (such as infantry & dire armor) or large monsters rather than other mechs their size, whose armor they often have trouble penetrating. The 5 headed version was the first designed, but the designers realized the design could be enlarged easily. While the Pyro variant was the original design, many builders replace the flame nozzles with other weapons due to availability & preference. Other variants include Cryo (frost launchers),Desert (sand blasters), Fog (steam breathers), Ripper (large buzzsaws), Snapping (2 med. Lobster claws ea.), Spitting (large steam gun or shredder), and Swamp (water cannons). Here are the stats for the original design.
