The dragon up the is H2o delirious and right now del's  rider  is  Luke Patterson or cartoonz they grow up together. Luke one day finds a baby dragon and that baby dragon was able to talk but only Luke could hear. Because Luke is a demon so Luke takes care of Jon. Jon is a one of a kind dragon mixed with different types of dragons from the movie (How to train a dragon). Like for example he has change wing blood so he can change with his environment. He also has speed stinger blood so he can run really fast. 

People go after Del all the time so Luke protects him. Luke is in a gang called bbs. He and Jonathan need two move to the gang house because it's the safest place to be. Jonathan does not trust any one but his brother. Jonathan also doesn't know any one of Luke's friends. 

Luke takes Jon out for flights to stretch his wings. Jon's room is like a under ground enclosure. Jonathan as a human looks like this. 

Full human form.

Half form. ignore Wildcat hes not a zombie.

And Luke looks like this.

Vanoss eventually learns how to ride Del being teach'ed by Luke. One more thing Del really dos not like wildcat cuz Tyler tried to stab and shoot him. And Luke tells every one "your not allowed to have any sort of weapons in Jonathan's room. 

So hope you like the idea and comment telling me you wan't this idea. Bye
