This is a visual history I put together back in 2010 for an article I never got around to finishing.
Did you know Peach’s hair wasn’t blonde until Super Mario World? Even if you go back and watch the Super Mario Bros. Super Show, she had reddish brown hair.
Also, she wasn’t called Peach in the US until Super Mario 64. Up until then, all knowledgeable gamers knew her as Princess Toadstool .
