Miles is incredibly sweet and inncocent for a dream demon, unlike most he is completely oblivious to most situations proving quite child-like hinting at the possibility that he may be a younger demon. He is quite playful in his ways, resorting to playful games and good dreams, unlike the nightmares and riddles of his fellow demons. Miles is quite unaware of the power he has if he even has much power at all.
In Mindscape- Miles appears light blue and occasionally light green teardrop shaped demon with one eye and four small black limbs used for day to day life.
On This Plane Of Reality- Miles has the body of a 15-20 year old man with blue hair and semi-cat like eyes.
