Overwhelmed but ready for action, five aspiring space explorers learn they have the power to create Voltron, the most powerful robot in the universe.
When the Paladins are unable to form Voltron during a training session, Coran puts them through his own rigorous training in order to build a sense of brotherhood and trust between the Paladins. However, the Paladins fail miserably and are unable to connect. It is not until the Paladins engage in a food fight with Allura and Coran that they finally begin to work as a team and are successfully able to form Voltron.
As the Castle of Lions continues to prepare for departure, the team is met by the arrival of a local Arusian investigating the castle. Allura heads to meet the villagers along with Coran, Hunk, Keith and Lance while Pidge and Shiro tend to the rescued prisoners from the Galra battleship.
The team and Arusians celebrate Voltron's victory in the castle, but the festivities come to a halt when Pidge reveals his intentions to leave the team and search for his missing father and brother. As the team tries to convince Pidge to stay, Haxus, one of Sendak's soldiers, is able to sneak a bomb drone into the castle, causing it to destroy the crystal that powers the entire castle and severely injure Lance in the process.
Hunk and Coran meet local Balmerans, Shay and Rax, who help them hide from the Galra. Shay admires the two and wants to help them, but Rax is cautious and insists they leave. Hunk and Coran are able to sneak past the Galra to find a crystal, but are captured and imprisoned. Shay helps them escape with the crystal, but is captured by the Galra after her brother informs them of Shay's actions.
On the way to the Balmera, the team stops to help two rebels on the run from the Galra. Lance is trusting, but Hunk is skeptical of their intentions.
Allura, Coran and the Paladins return to the Balmera to free the natives, but the arrival of a Galra ship could force Voltron into action.
As the Paladins scramble to ward off a Galra monster, Allura hopes that her ancient powers can heal the Balmera and save its people.
Allura considers making a heartbreaking sacrifice to save the team when the castle mysteriously turns on them and sends them hurtling toward doom.
The team stops at an isolated and seemingly insignificant Galra space station and discovers how the empire is gathering its energy from the universe.
Zarkon lures Voltron into a battle on his ship, and when one of the lions is captured the team must get creative to defeat the Galra and return home.
The lions get separated when a trip through a wormhole goes awry, while Coran and Allura scramble to break free of a seemingly endless time loop. Meanwhile, Zarkon seeks to uncover the person responsible for the Paladins escape. Pidge exits the corrupted wormhole in a junk nebula with debris from various alien technologies, which she uses to send a homing beacon to the Castle which pulls Allura & Coran out of the time loop. Keith and Shiro crash on a nearly dead moon and try to survive creatures and Shiro is nearly dying from the wound Haggar inflicted on him in the previous episode.
Hunk and Lance crash-land underwater and follow a mermaid to a civilization whose queen promises to keep them safe and help find the others. While resting, Lance is kidnapped by a trio of mer-people who believe the queen to be mind controlling the populous. After freeing Hunk of the control and capturing the queen do they realize that the Baku, which was a food source to the people, was really an alien predator beast. Lance channels a new weapon from his Blue Lion and kills the Baku, and as a thank you the queen uses the old energy beacon which brings Pidge to their rescue.
Following the teams reformation after the corrupted wormhole, Shiro is in a recovery pod and vividly dreams the day he escaped- Galra scientist Ulaz releases Shiro, instructs him to get back to Earth and find Voltron. Shiro also expresses that not all Galra are evil as a Galra (Zarkon) was the privious Black Paladin of Voltron. Finding space coordinates in Shiro's artificial arm, the Paladins find Ulaz, who reveals he is part of an order known as the Blade of Marmora who are hidden within many ranks of Zarkon's Empire. Praxas, who is remade into a Ro-Beast, finds the Paladins and quickly gains the upperhand, until Ulaz sacrifices himself to destroy the monster and let Voltron find the HQ of the Blade of Marmora. Shiro and the group decide to wait until they learn how Zarkon is beginning to track them. In his room, Keith holds a small dagger he has had since childhood which bares the crest of Marmora.
While making repairs to the castle, the Paladins encounter unusual spongy spores that lead them to a planet of brilliant engineers- the Olkari. When landing, Team Voltron meet the Olkari people in the forest, where they adapted from machine to nature based technologies. When rescuing the Olkarian king Lubos, Team Voltron find he willingly sold out his people as slaves to live in comfort, as he builds a super-weapon for Zarkon's forces. As Voltron engages the super-weapon, it learns and adapts to their attacks, even replicating them. After Pidge has help from the Olkari, she reconnects to her Green Lion in a way that allows her to summon a new weapon, which when the Black Cubes attempt to clone, instead grow massive plant roots. When leaving Olkarian space, the Castle of Lions is intercepted by a Galra war fleet.
Exhausted after a battle, the crew must spring back into action when Zarkon's forces track them down. Coran gets infected by a slippery virus. As they manage to escape, it is only after jumping that their wormhole generator is malfunctioning due to broken focus lenses. When Team Voltron attempt some rest- Lance and Keith try to make it to a pool, Hunk makes transparent blue cookies, Pidge learns beginner Altaean, and Shiro is on watch. Zarkon's ship discovers them again and another battle and jump leaves them without anymore crystal lenses needed for another wormhole. When hiding in a cosmic storm cloud, Allura comes to some realization that Zarkon is following them by tracking her energies. In engineering, Coran details what type of lenses they need, then Pidge remembers Hunk's cookies are exactly what they need. Coran positions the paladins in a unique fashion INSIDE the wormhole generator in order for it to fully function. Using his Slipperies, Coran lubricates the lenses to fully jump the castle away from Zarkon.
On the ravaged planet of Taujeer, Galra commander Marvok strips the planet of resources and prevents the citizen's escape. Allura and Keith go off on a separate mission to learn how Zarkon is tracking them down and on their isolated trip debate if any Galra people are even fighting Zarkon's rule. The remaining foru Paladins arrive on Taujeer to help the Ark escape, only to be fired upon by Galra forces closest to them as Zarkon located them none the less. When Keith & Allura are informed by Coran they try to use the booster jets to arrive sooner but end up destroying their pod. Hunk activates a new power up for his Yellow Lion which prevents the Ark from falling into a lake of acid. The Red Lion ventures into space to Keith & Allura's position and retrieves them to form Voltron, which defeats the Galra ship. After saving the Ark and resting in the Castle, it is apparent to them now that Zarkon is following them by way of his old connection to the Black Lion.
Shiro attempts to create a deeper bond with the Black Lion, while Coran takes the others to a swap meet, where they have some strange adventures. After Coran details his time in the swap meets as edgy and filled with space pirates, they arrive and find it to resemble an average mall on Earth. Varkon, a bumbling mall rent-a-cop, sees the four Paladins drop their terrible disguises and pursues them through the mall. Keith goes to a knife salesman for information on the blade he has, but learns it is from an extinct people before the salesman tries to steal it from him. Hunk is made to work off a tab for Sal, the owner of Vrepit Sal's diner, and earns a mass customer following with his gourmet skills. Varkon finds Hunk and he races out. Pidge and Lance find a shop which sells Earth material from the 1980's. Hunk meets up with Keith, then Pidge with Lance (after they bought everything in the store) and finally meet up with Coran who has the lenses. Meanwhile, the Black Lion reveals how it was created, and how Zarkon & Alfor were once friends. Zarkon then connects to Shiro on the psychic plane where the difference in power is vast, but Shiro's words of trusting his Lion earn its protection and defeat of Zarkon in the psychic plane. Waking up, Zarkon loses more connection to the Black Lion and Shiro is now more connected to the Black Lion. Afterwards, knowing Zarkon can't track them, Shiro orders the Castle to the HQ of the Blade of Marmora.
Upon reaching the HQ of the Blade of Marmora, it is located in a safe spot between two black holes and a blue Supergiant star. Keith and Shiro travel to their base in an effort to align with the Blade of Marmora led by Kolivan and his lieutenant Antok. But Keith's possession of one of their blades causes immediate friction with the Trials of Marmora to resolve them one of two results: knowledge or death. Keith must fight to unlock about his past, and with each fight exhausts himself more and more. When entering a vision of his old home with his father, the outside of the house shows a Galra invasion, giving Keith a choice: stay and learn, or leave and rescue. The Red Lion attacks the base sensing Keith's endangerment, and upon deciding to end this mistrust and gain their alliance, Keith relents his dagger, only for it to awaken its true form of a saber upon his enlightened decision and revealing a truth: Keith has part Galra ancestry. Meanwhile, Commander Thace (the Marmora spy who shutdown the Solar Shield) alerts the Order that the investigation is increasing and the timetable must escalate to now!
The Paladins split up to gather resources for a showdown with Zarkon. Hunk and Keith travel into the belly of the planet-devouring creature known as a Weblum for scaultrite, a material needed in wormhole generators. While there, the instructional Coran made is dated to when he was in university and is corroded. The duo successfully enter the Weblum, but are separated after the first stomach, leaving Keith in the second and Hunk in the Weblum's bloodstream. In the second stomach, Keith finds a trapped a silent Galra pilot who helps him journey through the third stomach to reach the scaultrite. As the Weblum's defenses flare, the only way to make the scaultrite is for Hunk to threaten the beast enough outside to form the crystals. Upon the Weblum firing its beam, Keith packs more than enough scaultrite, but the Galran with him holds him up for a single full bag, and escapes. Keith thanks Hunk for his efforts, and Hunk pokes at Keiths newly learned Galra ancestry.
By the information provided by the Blade of Marmora, Lance, Pidge and Shiro infiltrate a facility to free the only prisoner of the Galra Space Station Beta Traz. Upon successful infiltration, Pidge locates two cells instead of the one they were informed of. Pidge stays in the Main Command Center, but Lance and Shiro must reach and connect to the isolated Third level holding the two prisoners. Lance gains a 3D render of a Galra officer for the facial recognition. They each think they've found the right inmate, but it gets harder to tell as Pidge goes radio silent when the station warden goes to the Command Center. Lance escorts his choice out, while Shiro deals with his being impossible because of his predicting statistical improbabilities of his death from the smallest thing. When Pidge is disabling the remaining security features, she finds footage of her brother Matt's escape. When the gravity is shut off, Shiro with Slav regroups with Lance, who learns he actually has the warden's personal pet Laika. In the hangar, everyone is regrouped but the Warden overpowers them until Slav opens the hangar doors to save the Paladins. Lance uses his aim to save Slav from the Warden and the mission is a success.
Allura travels to the Balmera to acquire a powerful crystal. When she is about to leave with the crystal, the panoptic Ro-Beast from their last encounter prompts her to call on the Paladins for help. The creature, now merged with part of the encasing crystal it was once in, makes its way to the Castle as Allura goes skyward to protect the Balmera. Allura warps in the Paladins who regroup to their Lions to form Voltron. As they fight it, the team utilize their new weapons to subdue the Robeast and form Voltron to finally destroy the monster. Back on board the Castle, it is more apparent that since learning Keith's part Galra, Allura has a cold attitude to him. On the Olkarian home world, the super teludav is operational, and the team reminisce about their time since coming together. Meanwhile, Thace makes the error of returning for a spy device he planted, only for the Druids to intercept and capture him.
After acquiring the teludav from Olkari, the team prepares to launch the operation to defeat Zarkon and bring peace to the universe. When the Marmorans haven't heard from Thace, they urge a delay in action, while Allura argues they continue. Keith plans to infiltrate the main ship of the Galra Fleet, but before leaving Allura stops him to explain that since waking up she views the Paladins as her new family and his being part Galra made her unsure. Following Thace's capture, the Druids interrogate him, and allow him to escape. Haggar helps Zarkon find the Black Lion, Zarkon's fleet arrives, Shiro distracts while Keith sneaks aboard. Despite that the battle is a trap, Zarkon is too engrossed in reclaiming the black Lion. Since the Druids rewrote the shield codes, their plan adapts to turn the core room into a bomb and cripple Zarkon's ship. When the Druids are sent after Thace while Zarkon has a rematch with Team Voltron. Thace sacrifices himself to cause the power core to overload and explode, just as the cloak teludav loses its cloak, and Zarkon's ship loses power. As Zarkon's ship is wormholed to another reach of the universe far away, the Paladins pursue to finally end Zarkon.
The Paladins fight to systematically destroy the base to prevent Zarkon's return. As Zarkon himself goes to battle Voltron, Haggar & her Druids go to protect their emperor as he readies his armor, which untested could kill him as well as Voltron. Before Zarkon can do anything, Haggar uses her dark magic to forcefully remove the Quintessence from Voltron, but is overloaded by the purity of Volton. While the Lions are unresponsive, their Paladins still live, but Zarkon arrives in a Ro-beast in his image. Allura uses whatever power she can to stall Zarkon to allow the Paladins to recover and battle Zarkon's Ro-beast. Allura, Kolivan and Antok go to battle Haggar to keep her from using her witchcraft from delaying Voltron. As their battles rage, Zarkon splits Voltron back to the individual Lions; Allura and Kolivan triumph in their fights, while Antok perishes at the hand of Haggar and another Druid. Shiro awakens to see his team being beaten, and the Bayard access port in his Black Lion activates, activating its Transcendent Wings to phase through Zarkon's Ro-Beast and reclaimg the original Black Bayard. As their fight continues, Haggar is revealed to be Altaean, and Allura learns she has the power to command Quintessence, which she uses to defeat Haggar and Kolivan avenges Antok. Forming Voltron, the Paladins fight with new strength and Shiro uses his Bayard to supercharge the Voltron Sword and destroy Zarkon's Ro-Beast armor. After the battle, back in the Castle hangar, the Paladins discover that Shiro has vanished from the Black Lion leaving the bayard behind. On Zarkon's ship, Zarkon is on life support, prompting Haggar to summon Prince Lotor.
In the wake of Zarkon’s defeat and Shiro’s disappearance, the paladins struggle to move forward with no one able to pilot the black lion or the ability to form Voltron. The team must quickly devise a plan as the ascension of Prince Lotor and his generals pulls the team into a perilous game of cat-and-mouse that tests their unity and abilities more than ever before.
