|Behind the Scenes|
The hydra (a.k.a. copperheads) is a large variety of creature infected by the Blacklight virus.
Hydras have a snake-like body with a mouth that splits sideways and a tongue layered with sharp teeth and a reddish exoskeleton. The whole body of a hydra is only partially visible. Also, despite its' immobile appearance, hydras can burrow underground. The hydra's tongue appears to be armor-piercing as it is shown to kill the crew of a thermobaric tank.
The main attack for Hydras consists of grabbing loose debris or cars and tossing them at their enemies. This ability makes Hydras lethal to aircraft, as one or two hits can down a helicopter. However, Hydras pose less of a threat to armored vehicles, as their car-tossing ability is ineffective against tanks. When surrounded at close range, Hydras sweep their heads 360°, knocking them back. Finally, they are armed with tongues festooned with teeth, which they will use in combination with the "flaps" on the sides of their mouth to inflict a vicious bite.
