The Green dragon was of huge size with an unknown gender (likely male). This Dragon possessed the ability to breath fire.
This Dragon chased Seth, Kendra, Dougan, Trask, Gavin (Navarog), Mara, and Tanu along with a yellow Dragon and a red Dragon until the red left to chase after Seth and Tanu while the green and yellow trapped the others. Later the green and yellow fought Navarog in Dragon form but the green, yellow and a gray as stated by Navarog were killed and Navarog found the body of the red with a huge arrow in it's chest.
