Kai Master. Full name Kai Long.
A self trained 'master' of Xunyao and also a disciplined martial artist.
He's a young dragon that wishes to take over Big Master's credit in the eyes of everyone as the superior. Though he plays the helpful and encouraging 'friend' in the craft to Big Master he is really only meddling and messing up the training with Hiro. He hopes the disasterous training will make Big Master retire and turn Hiro to Kai Master.

His meddling causes for some interesting results and experiences Kai Long himself often can't escape from in time, thus leaving him to his own medicine.
