You didn't think the Flying Machines would be this sturdy to go into battle, huh? Surely if they couldn't survive a Fireball the Master Builder wouldn't risk entering them.

The Battle Machines are always there to keep the Master Builder going (the Master Builder specially engineered these to be sentient).
