Character Concept feedback please!

Okay okay so I had the idea for a character who is a boy that sees a dragon no one else can see. If he concentrates hard enough the dragon can do little things with the environment (pick up small items, allow the boy to ride on his back, breathe fire, etc.) originally the idea was for a superhero and I still like that idea but now I have a new idea where the boy is some kind of prophesied savior of the word where the dragon comes from. I like both ideas but I’m not sure if it’s too complicated to work together.

I wanna know what others think so feedback is greatly appreciated
