Miriam Mythos (ミリーアム ・ミーソス Miriiamu Miisosu), commonly referred to as Mirey (ミレイ Mirei), is a Sonic: Next Generation character. She is the eldest future daughter and second child of canon character Shadow the Hedgehog and fan character Azure the Dragon. She is an anthropomorphic 12 year old dragon-hedgehog hybrid and the younger sister of Azreal Mythos II and older sister to Kiyo Mythos. She inherited her mother's lightning powers as well as the ability to use Chaos Spear and Chaos Lance from her father.
- Miriam was originally going to be named Maria, after canon character Maria Robotnik, but changed to a different, but slightly similar name to avoid association between the two characters.
