User blog:BandicootBro/So what do you think of my first character?

Graphene the Echidna

This is my first character, I named him after the strongest material known to man, his strengths powers and weaknesses are based on Toph from Avatar: the Last Airbender. However I've tried to make his story and some other things as original as I could so please tell me what you guys think and how I can improve this guy.
