It wouldn't be a true fighting type video game if there wasn't a commentator for each round of battle, but luckily, Arms didn't disappoint by remembering to include such a key component. The commentator found within the game goes by the name of Biff, a little guy there to tell fans all they need to know with just about everything. From describing opponents to explaining the arena one is fighting in, as well as chiming in on what is happening before, during and after a fierce match, Biff is there to inform all who care to listen.
