I'd like to point out that Will does all his fighting with his flute, and yet he can fight everything in the game by himself, as that flute tears enemies up.

But the game gives you the ability to transform into Freedan anyway. He uses a sword, doing double Will's damage. It also increases his range. He can also take more hits. He also runs faster. He also gets special moves which add a ton of extra utility like AOE, projectiles, and greater damage.

Freedan is completely broken and overpowered, and you just don't care because he's completely awesome.
