Rey's hair is blonde, a golden shade of hair as bright as the sun. He has the same green eyes as his lord father Diago. He is more on the lean and agile side compared to his older brother rein, but he is also no slouch in battling. He is quite a handsome and attractive young warrior as well. He is considerably tall in his humanoid form although shorter than his oldest brother rein. His dragon form is a huge dragon of golden scales and mischievous emerald green eyes. He is the secondborn son.
