Toph was one of the show’s best characters. It was kinda funny she didn’t appear until the second season. She is a blind rich girl who happens to be the best earth bender.
She was crazy good, one of the few characters I really believe was superstrong instead of the plot making it work out for them.
She was tasked with teaching Aang the power of Earth bending. While he struggled, she was a good teacher I think.
I absolutely loved her humor and blind jokes. They always put a smile on my face.
She also discovered the art of metal bending, as metal and earth aren’t that different.
I don’t believe the heroes could have toppled Fire Lord Ozai without her help, even though she didn’t actually fight him for real.
