Characters that changed their appearance.

[Yabuturtle]

I know it's common for cartoon characters to change their appearances but I'm wondering which ones did you like best.

I remember Bebop who's head hair was all purple and then later on it, partly purple. I also remember Rocksteady wore his helmet in the 1st season but took it off later.

I noticed Krang's appearance changed too, although slightly. In the early episodes he didn't have gloves but later on he's shown to wear red gloves? Which do you think looked better.

There's also the Turtles themselves. in the Red Sky season they changed a little, having sharper features and their masks were shaped a little differently. To me, they always look like they're mad at something, even when they smile. xD Which appearance did you like best?

There's one other character which is the Rat King. We know what he looked like in the earlier episodes but in the Red Sky season he had a coat and a hat on. Which appearance did you like better?
