With Earth and its allied worlds suffering from dangerous levels of overcrowding, Galaxy Garrison sends the Stellar Ship Explorer into the Near Universe to search out new worlds. However, doing so brings them critically close to the evil Drule Empire. For protection, they develop 15 exploratory spacecraft using an ancient super-technology and train their pilots with the secret of assembling Voltron.

The Stellar Ship Explorer has landed on a new planet and is preparing to set up a permanent base. Drule fleet commander Hazar has gotten word of this plan, and has decided to capture the planet and the Alliance facilities in one fell swoop. However, his assistant Captain Quark gets impatient, and launches a full-scale assault while Jeff and the rest of the Voltron Force are busy scouting the planet.

Hazar issues an ultimatum to the Explorer and her crew vacate the planet or he will obliterate it. Jeff, Cliff, Krik and the rest of the Voltron Force try to stop them, but the planet is too fragile and begins to explode. To escape the doomed planet, the Land, Sea and Air Teams must combine to form Voltron while under heavy attack from all sides.

Krik's sixth sense leads the Stellar Ship Explorer to a strange black hole cluster. A faint distress call convinces Commander Hawkins of the need to investigate, so he sends in the Sea Team. However, the entire team is soon lost in the Sea of Holes, and there they encounter an enormous Robeast! As Jeff rushes to the rescue, Krik wonders if his sixth sense has doomed them all.

Cliff and his Land Team are sent to explore a seemingly barren planet. The crew are surprised to discover strange vegetation in several areas of the planet, each patch near a crashed rocket. Ambushed by hidden defenses, the Voltron Force rushes into battle. Meanwhile, Hawkins realizes that the planet is already being terraformed by the Drules, and this time the humans are the invaders.

The Explorer is caught in a terrific storm of meteors, and is badly damaged. Captain Mongo of the Drule Empire moves in to take advantage of the situation. Jeff and the entire Voltron Force don space suits to help with the repairs, desperate to finish before the enemy gets to them. But Mongo has an even bigger trap in the works, one that could destroy the fleet.

Galaxy Garrison decides to send the Explorer into enemy space to try and make peace. Giving their word that they will not use Voltron, Hawkins and his crew approach the Drule Empire. To keep them safe, they are escorted by Commander Kio and his squadron. When Kio's squadron is ambushed by the Drules, our heroes disobey orders to go and save him.

The Explorer arrives at a new planet, only to find a strange Ghost Fleet appearing and disappearing around the globe. Intrigued, the Voltron Force begins a wild goose chase as the Explorer waits in a central lake. Hawkins has a bad feeling that the planet holds a terrible secret, but will they figure it out before the Ghost Fleet strikes?

Working around the clock, the crew of the Explorer is at the point of collapse. Captain Newley and Commander Hawkins have no choice but to set down on a nearby planet and give everyone shore leave. Meanwhile, the supply convoy they are scheduled to meet up with is ambushed by a Drule attack!

Cliff and his Land Team find an ancient city on a forgotten planet. While exploring, Cinda and Modok find an army of strange bats. Modok goes berserk before finally collapsing, burning up with fever. It seems the bats have given him a strange virus. Then the Drule fleet attacks, but without Modok our heroes cannot form Voltron!

A young Drule pilot crashes during training exercises and is saved by Jeff and the Voltron Force. Nursed back to health, the pilot begins making friends. Newley and Hawkins think that the Drule pilot could become an emissary of peace. However, Sea Team member Shannon has a brother who is a POW, and being friends with a Drule doesn't sit well with him.

The forests of a dead world reminds Wolo of his childhood, growing up with his brother on a faraway planet. As he remembers when his brother was seriously hurt saving his life, an earthquake puts him in immediate danger. Without his brother to help him, Wolo must act on his own to save himself, and the entire Voltron Force.

As the Explorer approaches the deadly planet of Itlon, they receive a mysterious distress signal. Risking their lives, the Voltron Force descends to the planet only to find the evil Nerok and his attack fleet. They are sitting in the middle of an electrical storm, and seem to be in trouble. Are they disabled, or is this Nerok's most risky trap yet?

A mysterious comet passes very close to Earth, causing the populace to panic. Seemingly under the influence of the comet's strange radiation, General Steel orders the Alliance ships to stage a pre-emptive strike on the Drule Empire. Unfortunately, the Drules predicted this effect and are lying in ambush.

Commander Hawkins finally convinces the Drule Empire to engage in peace talks. Bravely going to Captain Mongo's ship alone, he convinces the Drule leader of his good intentions. Before they can finalize a plan for joint exploration of space, Brak decides to use the peace talks as a distraction to launch an attack on the Voltron Force.

An uneasy peace has been established between the Alliance and the Drule Empire. But Galaxy Garrison is unable to reach a consensus in time, and a local fleet commander refuses to withdraw from a Drule planet without official orders. If Hakwins and the Voltron force don't convince him to leave, they'll be in violation of the truce.

Infighting among the Drules makes it impossible for them to make a move for either peace or war. On the Explorer, the crew gets surprise news as they try to meet up with the Drule for peace talks. Captain Newley is being transferred to Galaxy Garrison headquarters. It is an honor, but the captain has many important friendships he will be leaving behind.

After countless false starts, the Voltron Force finally begins joint explorations of new worlds with the Drule Empire. However, Nerok calls in a favor with the Imperial Council and manages to get command over the peace effort. His first order to the exploration force is to forget the peace effort and prepare for attack!

The Voltron Force discovers signs of an ancient civilization on planet Neb. However, the planet is unstable and Nerok is right behind them, ready for an ambush. Hazar meets with his father, Chancellor Mozak, to consider the fate of the Drule Empire. They realize that the empire will lose if they try to attack Earth, and peace is their only long-term option.

Colonel Cross sets up a new Alliance supply base, but he is under heavy Drule attack. Because of his pride, he refuses to call the Voltron Force for help, but Krik senses that something is wrong. The Voltron Force rushes to the rescue, but they are ambushed by a new Robeast and Jeff is knocked out. Can Voltron fight without a head?

The Explorer and the Voltron force are in bad need of additional funds to continue their operations. Steel and Newely appear before the Alliance council to get more support for the Explorer program. They also explore the option of building yet another Voltron Unit. Back on the Explorer, the team trains to be stronger for their next encounter.

Marshal Keezor brings news that Hazar has been demoted, and Nerok is finally given permission from the Drule council to go on the offensive. He immediately orders Mongo, one of the few Drule commanders who still agrees with Hazar, to attack Voltron's support fleet. Despite his misgivings, a direct order gives Mongo no choice.

Mongo is forced to launch an attack on the Alliance agains this wishes. The Alliance fleet commander decides to concentrate all fire on the flagship, in hopes that the fleet will retreat if their commander is lost. With his ship quickly disabled, Mongo decides to fight a losing battle to prove his loyalty to Hazar and the empire rather than retreat. Meanwhile, Nerok uses this time to set up an ambush at the fleet's rendezvous point.

Hazar returns to planet Drule to try and convince high command to make peace with the Alliance, and plead his case against allegations of treachery. Despite help from his father and his sister Dorma, he is attacked by a mob of citizens, and then sentenced to exile on planet Dreska. In honor of the efforts he made for peace, the Voltron Force decides to name the planet he saved "Hazar."

Jeff leads his Air Team onto the surface of a mysterious planet, when an energy pulse in the atmosphere drains the power supplies of his entire crew. Cut off, he's ambushed by Zabar, and is helpless to protect his team. Back on the Explorer, they desperately search for a way to help without becoming disabled themselves. They need Jeff for Voltron,and a Robeast is on its way.
