Haggar tells Zarkon the story of the Omega Comet, which is mysterious in that it behaves like a black hole by sucking everything it passes up with its massive gravitational pull. Voltron at one time had stashed the comet away into a far corner of the universe where nobody could find it - until now. With Romelle on deck to witness it, the Doomies send the coment on a course for Arus. Romelle manages to get a warning call out to the Castle of Lions about the Comet and of course Coran knows exactly the danger they face in the path of the comet.
