Oh gosh. I guess if we're talking recent, that would be both Rioko and Moira. I have some WIPs of them as children, I've drawn them at 14 and even drew Rioko in her 20s. Personality, Rioko has changed the most. She went from a shy baby who was afraid to talk cause she didn't know basic Mobian (English), to a hothead cock-sure shit first ask questions never, to a kind and loyal person. Stay tuned. There is more to come!
