The Galactic Guardians - S1.E31

Following a recent fight, the Galactic Guardians reminisce about past battles. In a flashback, it is shown that a transporter ship carrying poison gas was blown off course as Hydron and Flipshot train the Galactic Guardians' new recruits Artilla, Spinwit, Tuskador, and the previously-unknown Sagitar. Skeletor plans to destroy the ship with the Galactic Guardians still on board.
