Defenders of Arus

Daniel and Vince meet a fellow Cadet named Larmina, who is revealed to be Princess Allura's niece and the trio are given their "Voltcoms", special gauntlets that access special abilities within them and will allow them in the future to pilot the Lions. As Pidge and Hunk go to rescue Keith from drifting into space (due to the fact that Wade's experiments on Black Lion have left it barely with any power), a Robeast is sent to Arus by Kala and Maahox to battle the Voltron Force. Lance and Allura realize that they must fight it without the other 3 Lions. When the fight gets too much for Lance and Allura, Daniel and the others get to the Green (Vince and Larmina) and Yellow (Daniel) Lions to help fight off the Robeast alongside Lance and Allura, but even that proves to be not enough to turn the tide. Pidge and Hunk save Keith and send him into Arus' atmosphere to crash land on the planet, accidentally decapitating the Robeast and destroying it. As Lotor watches in anger, Maahox explains how the same Robeast was from his time and the beasts are not enough to defeat the Voltron of today.
