Here's my Lion King/Timon & Pumbaa OC Armie in his dragon form. I happened to study the color palette, and used my bold, bright and colors of the world markers to get things right. He still has his father's mutated fur, legs, spikes, hair and nose, but the tail feathers are now on the tip of his new dragon tail. The wings match his back.
In fact, this is the first form he changed into upon learning that he's a changeling.
