Garfle Warfle Snick
Bob
Voiced by: Jeff Bennett
The host of the comedic game-show Garfle Warfle Snick, but he's not what he appears.
- Beware the Silly Ones: Bob may seem like a comedic figure, but he's a powerful reality-warping inter-dimensional entity and the price of failing his tests means death.
- Cosmic Entity: Bob is a deific figure said to judge the worthiness of warriors... disguised as a cheesy game-show host.
- Deadpan Snarker: Bob has a wry sense of humor, picking on Lance for being the dumbest of the Paladins.
- Game Show Host: Bob is a cosmic entity who hosts a game-show, where those who fail are fed to a Snick — the Arachnid-like crustacean monster that Kuron encountered in "The Journey".
- Graceful Loser: He is very happy the Paladins won Garfle Warfle Snick. Justified since his whole motive is testing heroes so that they may achieve greatness.
- Great Gazoo: He's a diminutive four-armed green alien with buck-teeth and oddly shaped antennae, deific powers, and a penchant for mischief, posing as a game-show host. He even repeatedly calls Lance a "dum-dum", and seeks to teach the Paladins a lesson regarding the importance of friendship.
- The Omniscient: Zigzagged. He knows every detail about the Paladins, their adventures, and the people they met along the way. He didn’t see Pidge hitting him with a golf ball coming through and seemed legitimately surprised the Paladins won.
- Or Was It a Dream?: After beating his game the Paladins wake up in their Lions thinking it was all just a dream... until they all realize they shared it.
- Physical God: Coran states that he's a cosmic entity — a la Q from Star Trek — who seeks out and tests warriors, and those who pass his tests are destined for greatness.
- Power Echoes: When he gets serious, his voice becomes distorted and echoic.
- Troll: He goes out of his way to harass Lance. When he's trying to guess the names of people the Paladins have met, the spinner appears to stop on someone Lance remembers... before skipping one more to someone he doesn't.
- Well-Intentioned Extremist: He a tester of heroes and seemed to put the Paladins on the gameshow in order to test their friendship so that they are ready for the challenges ahead... Thing is failing his show is likely to result in being stuck there forever or dying horribly. The Paladins themselves lampshade this, being honored to have won his test but also thinking he was a total jerk.
New Altean Empire — Spoilers
General
- Easily Forgiven: No one blames the Alteans for being Honerva's pawns, even when they destroy entire planets and enable Honerva to break reality.
- Karma Houdini: Thanks to Allura restoring reality and undoing most of the damage, most of the surviving Alteans don't get tried for their war crimes against the galaxy from season 8. By this point they had destroyed several planets for their quintessence while robbing the regeneration cubes from Olkarion.
- Unwitting Pawn: Allura believes they are due to Honerva lying to them about the circumstances of Lotor's death and using them to power the Robeasts.
Luka
Voiced by: Kari Wahlgren
A female Altean found in the core of the mysterious mech that appears at the end of season 7, serving as its power source.
- Ambiguously Evil: As she was unconscious, there's no way of determining whether she was complicit in the attack on Voltron or was simply being used as the mech's power source. Season 8 confirms that it's a bit of both, as she sought to avenge Lotor.
- Back for the Dead: Played with. She was never killed in the fight with Voltron in the Season 7; merely rendered unconscious. But after waking up briefly in the first episode of Season 8, she suddenly flatlines while going on a rant about Voltron and Honerva.
- Evil Redhead: In Season 8 Romelle remarks that Luka was difficult to get along with when they were growing up together, but not evil. By the time they're reunited, however, Luka has been swayed to fight against the Paladins.
- Facial Markings: Has two red markings on her upper-cheeks, showing that she is an Altean.
- Last Episode, New Character: Revealed at the end of the final moments of season 7 after Sam brings Allura to see the battery that was powering the ship.
- Living Battery: Sam specifically points out that she's the power source for the mech, as well as its pilot.
- Purple Is the New Black: She wears dark armor that seems reminiscent to Lotor's armor.
- The Reveal: At the end of the final episode for season 7, Sam tells Allura that they found the power source for the mecha that attacked Voltron was an unconscious Altean.
- Surprisingly Sudden Death: When ranting on to Romelle on how she betrayed them, supposedly by Honerva's doing, she goes into a shock and then flatlines. It's revealed that Honerva bonded the surviving Alteans to dark entities from the Quintessence field — of the same sort that corrupted her and Zarkon — and can use these entities to remotely observe, control and even kill them.
- Treachery Is a Special Kind of Evil: How she views Romelle, saying she betrayed the Altean colony by siding with the Paladins of Voltron who killed Lotor.
- Ungrateful Bastard: The humans she tried to kill save her life after she spends months unconscious. Instead of even talking to them, she remains sullenly silent.
Merla
Voiced by: Adelaide Clemens
- Decomposite Character: Given that most of the elements associated with her original series counterpart of the same name has been incorporated into Team Sincline, the only notable things that she is associated with her original counterpart would be her name, being a villain who then reforms and the red hair.
- The Dragon: She becomes Honerva's second-in-command in the New Altean Empire, and was the one who handpicked Luka to pilot the prototype Komar Robeast.
- Heel–Face Turn: She is the first Altean to suspect that Honerva is using them, and turns against her comrades to fight alongside Voltron and the Atlas.
- Not Quite Dead: She's seemingly killed when she uses her Komar Robeast to shield Voltron from Honerva's Robeast, though she survives as she then tells Team Voltron not kill her friends, along with later showing up alongside Coran on the restored Altea.
Ven'tar
Ven'tar
Voiced by: Kari Wahlgren
An alien who Lotor befriended at a planet he stayed at in "Shadows".
- Posthumous Character: She only appears in flashbacks in "Shadows" and is likely among who those who died in the planet's destruction from Zarkon.
- We Hardly Knew Ye: Only appears for a couple of minutes before her planet is destroyed.
The Alternate Universe
Slav
Slav
Voiced by: Iqbal Theba (English), Arturo Castañeda (Latin American)
Slav's Alternate Universe counterpart.
- Alternate Universe Reed Richards Is Awesome: Unlike the Lovable Coward from the main universe, this Slav uses his knowledge of alternate timelines for various acts of badassery. While our Slav is paralyzed with fear by obsessing over all the realities where he fails/dies, Alternate Slav energetically looks towards all the realities where he succeeds, and is a badass.
- La Résistance: Fights as a freedom fighter against the Altean Empire.
Sven
Sven
Voiced by: Josh Keaton (English), Ricardo Tejedo (Latin American)
The alternate universe version of Shiro.
- Ambiguously Gay: Only because he is his reality's counterpart of Shiro. Given the fact that they don't even have the same name and aren't even the same nationality, it is up in the air of just how similar they are, so they might not even be the same sexuality. In any case, he doesn't have enough screen time to establish anything about his love life.
- Mythology Gag: His entire existence is this to Shiro's counterpart Sven Holgersson from the original Voltron, but most notable is his line "Get me to a space hospital." referencing how his death was censored.
- Taking the Bullet: He jumps in front of a laser blast aimed at Lance.
- What the Hell Is That Accent?: He speaks with some sort of Scandinavian accent, like his namesake from the original show. His voice actor stated he was told to ad-lib the accent, without prior knowledge or preparation beforehand.
General Hira
General Hira
Voiced by: Virginia Madsen (English), Carla Castañeda (Latin American)
The commander of the Altean force that the Paladins encounter in the Alternate Universe, who wants to obtain the transdimensional comet in order to spread Altean "peace" to all realities.
- Anti-Villain: Genuinely wants peace and to get rid of worldly suffering. Pity she's fine with enslavement...
- Bitch in Sheep's Clothing: She's very polite and reverent towards Allura, but her actions are monstrous.
- The Evils of Free Will: She's perfectly fine with transforming others into "non-cogs" by using neural implants to remove their willpower and turn them into docile slaves to the Alteans, since she believes this is the only way of obtaining true peace in the universe.
- Knight Templar: Like the rest of the Alternate Universe Alteans, she believes in spreading peace and unity everywhere, at all costs, no matter what they need to do to force others to comply.
- Light Is Not Good: Like most Alteans, she resembles a fantasy high elf with a shining armor, but is evil.
- Multiversal Conqueror: She wants to use the comet to spread the power of the Altean empire to all realities.
Altean Scientist
Altean Scientist
Voiced by: Dee Bradley Baker (English)
The scientist who serves not only as Hira's second in command, but also as the main researcher and scientist helping Hira spread "peace" amongst the universe.
- The Evils of Free Will: He's willing to use the Hactra to neutralize the non-cogs will if it means they will have peace.
- Evil Genius: He uses his intelligence to help Hira convert those who are aggressive into docile workers, willing to do anything they're told.
- Expy: Appearance wise he looks an awful lot like Shou Tucker. Probably not a coincidence.
- Light Is Not Good: He wears white clothes and seems generally cheery, but he has evil motives.
- No Name Given: He's never referred to by name or title.
- Scary Shiny Glasses: His glasses shine a lot, especially more when he talks about how he and Hira spread their "peace" amongst the galaxy.
- Stepford Smiler: He doesn't seem to ever speak without his smile, to the others slowly growing discomfort.
- Insistent Terminology: He always insists that the non-cogs are not slaves.
Dark Rift Creatures — Spoilers
Dark Rift Creatures
Voiced by: N/A
Mysterious abominations that came from the quintessence rift on Planet Daibazaal. They are the first major enemies of Voltron in the series' backstory.
- Always Chaotic Evil: They are motivated by destroying everything in their path until there is nothing left.
- Bizarre Alien Biology: These monsters can also enlarge themselves when being partly destroyed.
- Eldritch Abomination: They're amorphous entities that originate from the Quintessence Field and may be made of corrupted Quintessence themselves, being capable of inter-dimensional travel, flight, amalgamating into semi-humanoid forms, and firing powerful energy beams. They can also parasitize and corrupt other living beings.
- Greater-Scope Villain: Despite appearing only in one episode, their impact makes them for the entire series. They are also indirectly responsible for why Zarkon became a Galactic Conqueror that enslaves civilizations across the universe.
- Small Role, Big Impact: They're also the reason why Voltron was created in the first place.
