Oh, a dragon, huh? Guess what, I have a dragon species called the Synddereevocks: Massive flying animals with wingspans on average of 900 yards.
*Synddereevock dragon trashes through your dimension, burning all in its path, kills and eats the dragon, and returns the trophy to me*
This is just too easy
*Rides away on Ellestellock dragon (another dragon from my Chris Lynheart series. Fastest flying animal on the planet. Reaches cruising speeds of 650 MPH)
