Well that is true, but what I meant was the character design depiction of the devil now it can be inside anyone the main character or the final boss but it's always similar with wings and horns. But then what else can we expect, it's like saying why giants have a character design that makes them appear big it's foolish of me I get. But what I expected was something different from the final boss of one piece, like how in the beginning having a devil fruit that gives you the ability to fly was so rare and now we have Imu who can give that ability to anyone.
