A one-sentence explanation of both references:1) Roronoa Zoro is an arguably insane master swordsman from the ridiculous (and bizarrely popular) anime series One Piece who fights with three swords.
2) Toph is a small blind pre-teen girl from Avatar: The Last Airbender, and she is so damn good at her style of fighting (it involves many, many, MANY big rocks) that she invented a new branch of it.
