Varan

"Varan is an Earth Defender with special affinity for forested and hilly areas. Although not capable of true flight, Varan's extraordinary leaping capabilities and gliding capacity mean that he rarely, if ever, touches the ground for more than an instant. Although he naturally lives in solitude, Varan has developed very finely-honed sonic projection capabilities which can be used to communicate over vast distances. These same pinpoint sonic waves can be used in battle to disrupt an opponent's sense of balance. Varan is quite possibly the most mysterious of Earth's native monsters—first-hand sightings of him by humans remain relatively rare."
