There will probaly be a book for this au itself ONCE I HAVE A FUCKING NAME FOR IT-
... anywayMMOOOOONNNNNNN
Okay so the moon on the top left is current Moon. Top right was when he was in the mafia. Moon in the middle is from when they were teenagers. Bottom right is when he had just gotten out of the mafia and was a wrecking on his own with his neighbor being sun. And bottom left is just what the marking on his back is.
Okay so none of this is a Canon design as its always changing, but I kind of like this- obviously he does actually look a tad different as a teen than how I drew him but heres some very important things in his design:
1. He dyed his hair when Sun helped him get better and they opened the library
2. Hes always just struggled with hair falling in front of his eyes
3. Teenage Moon had a mullet
4. He got scars all over him from the mafia
5. He was always getting hurt as a teen
6. He has a cresent-moon shaped vitigo mark/birthmark on his back. One that he's a bit self conscious of and one that when Sun discovers Moon is really anxious but Sun just runs his hands over his back just amazed at how he never knew about it
7. Present Moon wears sweaters and just really comfy things that are easy to throw togetherSo yeah-
MOON
