Stared at this page for a bit trying to think of who King Piccolo reminds me of outside of Dragon Ball.
It's Nene from Blue Dragon.
Which given that I think Toriyama designed characters and/or art for the game, makes a lot of sense.
First seeing them in a technologically advanced airship, their general appearance as a very old alien-looking person, pointed ears, etc.
Plus, I think they had the same goal. Piccolo wanted his youth back, and I think Nene was developing an illness that he was trying to cure?
I just bring it up because I remember playing Blue Dragon a lot as a kid, and I think it's the only non-DB Toriyama game I played, since I never really tried out Dragon Quest.
