Fairy Tail season 5 episode 42
Episode title: Celestial Spirit Beast
Natsu and his fellow Fairy Tail members come face to face with the eclipsed Celestial Spirit King... except the king is now more like a giant fiend without a face! Or more like he's got a giant vacuum cleaner tube for a face, which he uses to suck up his own planet, the captive Celestial Spirits, and if they're not careful, the Fairy Tail Wizards!
