Luckily, Matt dodged those dangerous teeth in the nick of time, and flitted away from the opponent, swimming over to face his back and with all his might - the same thing he did with Shiro, though he figured the effect wouldn't almost be the same - he slammed him with his tail, planning in mind for it to burn or at least knock him down. 

His hands came up to the cuts on his stomach, hissing a bit, surrounded by crimson water. It hurt him to no end, but he wasn't going to stop until the opponent was done for.

Wherever he was right now, Matt hoped Shiro was going to be okay.
