Trouble is an aptly-named wyvern dragon. As far as dragons go, he is very intelligent and can often guess what his rider is going to ask for before they ask for it. He also tends to outsmart riders and handlers and becomes bored easily making him a nuisance. Furthermore, it takes a lot of time for him to come to trust anyone meaning he's very selective in his riders and often attacks potential handlers making him a bit of a hazard and resulting in his name. When a rider he likes is found, he becomes defensive and loyal. If the rider is taken away or leaves he suffers from separation anxiety, however, if given the chance he will take off on his own for days to weeks at a time. It just has to be on his terms. His favorite thing to do is be ignored/ignore others or steal their shiny objects

Fast and agile in the air (slow on the ground), cagey, and unpredictable in personality. A lot bit of a diva. Because of the build of his wings and the natural habitat of wyverns, it's very difficult for him to take off from a standstill on the ground. Cliffs/high places are the best spots for him. Otherwise it may take him a moment to build enough lift. He was previously used for aerial combat, something he excelled in. He can be quite vicious and will use his speed to dive bomb other dragons and their riders. He was retired due to his finicky and aggressive nature towards unknown handlers and stable hands but has kept his abilities and skill making him a dangerous opponent once in the air. He can and will perform these attacks unprovoked and of his own volition, even when not being ridden.

 He is very playful when he thinks no one is watching and enjoys playing on swinging objects, climbing the walls of his stable dome, hiding in high up places, and chasing rolling objects as well as collecting shiny things as male wyverns are prone to do for their nests.

He is very fond of Ghost meaning she is usually with him as a sort of calming companion even though she's only big enough for a child to ride.  Ghost often ends up with a lot of  the valuables Trouble steals. 

Trouble is cleanly obsessive and will preen and demand baths often. When stressed, he will preen the feathers off his neck and tail as well as loose colour in his scales by scratching them with his beak as he cleans obsessively. This problem can usually be solved by supplying him extra toys and almost always by giving him hugs and cuddles from his favorite people/Ghost.
