Terra and Toph both have some pretty good control over the Earth. Toph has extended this ability to work for sand and metal, but Terra has just focused on improving her rock abilities. I think Terra would have the edge in this round, since her hand to hand skills aren’t bad when mixed with the rocks. Not to mention that she got some battle armor thanks to Slade. Toph may be a little out of her league in this round, but it would be a good fight. Terra wins.
