New School Defenders (2011)

After Voltron's victory over Lotor and his army, the Robot Lions lost control during a celebratory event and nearly destroyed a city. Because of this, Galaxy Alliance commander Sky Marshall Wade ordered the Lions to be dismissed from their duty as defenders of the universe and disbanded the Voltron Force. Since that day only the Galaxy Alliance has been in charge of protecting the universe while Lance, Pidge, and Hunk are acting officers in the army, Princess Allura is ruling her home planet Arus, and Keith is a fugitive from the Alliance. Daniel is a mischievous and curious student in the Galaxy Alliance air school. Daniel and fellow student Vince are recruited into the Voltron Force as junior cadets and later become members of a resistance against Sky Marshall Wade, during which Keith infiltrates Wade's secret base and searches for the Black Lion. Now, as part of the resistance's plan, Daniel and Vince sneak into Wade's room and switch out his prized pin with a fake one and head back to "The Den", the resistance headquarters. The reason is that the 4 insignias on the pin are actually the keys to reactivate the Lions. Meanwhile, Keith discovers his Black Lion and breaks it and himself out of the base, contacting Pidge and trying to escape Wade's security.

Defenders of Arus (2011)

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.

Defenders of the Universe (2011)

After the events of Part 2, Wade goes insane and kidnaps the Alliance and replaces its soldiers with robots, while additionally holding Coran hostage. Meanwhile Lotor and Maahox plot to send a new Robeast to Arus to destroy Voltron as it is powered by a combination of Kala, the strategist that Maahox terminated at the end of Part 2 and Haggarium, the substance that Kala's energy apparently stabilized and resurrected Lotor. As the Lions fight the Kala Robeast (with Daniel piloting Red Lion along with Lance due to an injury he sustained in Part 2) and Keith and Larmina fend off Wade's robots on the ground, Wade (on another planet with Coran as his hostage) sends a massive Robot Lion to battle both Voltron and Kala. At one point the Kala Robeast literally absorbs the power of Wade's Lion (thusly severing the connection between Wade and the Lion) and forms a Mega Spider. Vince informs the team that he has completed the repairs of the Black Lion which sends Daniel back to the Castle using his "Speed Claws" Voltcom ability to retrieve it. Keith and Larmina board the Black Lion and upon Keith's command unite to form Voltron. During the skrimish, they learn that their attacks aren't working and all but the Black Lion are too weak to form the Blazing Sword due to being surrounded by Haggarium-laced webs. But, after a boost from Vince's Voltcom, Voltron goes to full power, forms the Blazing Sword and defeats Kala. Maahox, a scientist who seeks to revive Lotor, succeeds in bringing him back to life and explains how long he has been gone and the changes that have been made to his army.
