King Sombra, or simply Sombra, is a male initially-umbrum unicorn, the former tyrannical ruler of the Crystal Empire, and the main antagonist of the season three premiere, the season nine premiere, and the IDW comics' thirteenth story arc and My Little Pony/Transformers II. Princess Celestia tells Twilight Sparkle that he took over the Crystal Empire a thousand years ago but was banished into the frozen north. Before his banishment, King Sombra put a curse on the Crystal Empire which made it vanish into thin air. When the Empire returns, so does Sombra, who attempts to retake it. He is defeated by Spike, Princess Cadance, and the Crystal Ponies' use of the Crystal Heart.
In The Beginning of the End - Part 1, Sombra is restored by Grogar to join him in an alliance with other villains so they can conquer Equestria together and defeat Twilight and her friends once and for all. However, Sombra tries to take over Equestria by himself and, despite being able to destroy the Tree of Harmony and the Elements of Harmony and conquer both Ponyville and Canterlot, he is defeated again by the Mane Six.

Development and design
The show's story editor, Meghan McCarthy, and another staff member have stated that the character's name is Sombra. A tweet by Hasbro's My Little Pony Twitter account spells the name as "Somber". "Sombra" is a Spanish, Portuguese, and Galician word for "shadow", which comes from the Latin "umbra". A differently-shaded version of the armor around King Sombra's neck is used for the 2012 Design a My Little Pony Finalists poster, as part of Steel Masquerade's armor. Jim Miller, the show's storyboard supervisor and King Sombra's voice actor in season three, drew inspiration from the vocals of the Mastodon song "Crystal Skull" for his performance as King Sombra. Meghan McCarthy has said that King Sombra was inspired by Sauron from The Lord of the Rings and is meant to be a dark presence.
King Sombra is a dark gray unicorn with a black spiky mane and tail. Unlike regular unicorn horns, which match the pony's coat color and are straight and segmented, Sombra's horn is curved, smooth, sharp at the tip and it gradients from dark gray to red. He has sharp teeth with two visible fangs unlike other ponies and red—green when younger—irises, but most often his otherwise white eyes appear green and have a purple mist emanating from them, which disappears both times he is attacked. He wears silver armor on his legs and neck, a crown with horn-like points on his head, and a red cape that covers his flank. When his flank is shown briefly in Princess Celestia's flashback, he has no visible cutie mark. When he is turned to shadow in the flashback, only his head remains, and when he returns as an amorphous black cloud, only his eyes are visible at first.
The alternate universe version of Sombra in the IDW comics' Reflections story arc has a neatly smooth mane and tail with blue streaks. His horn is a solid color and segmented like other unicorns, and he still has green irises instead of red. He wears a light blue crown with a yellow gem, matching shoes and collar, and a purple cape instead of a red one. After the alternate Sombra absorbs the evil from alternate Celestia and Luna, he closely resembles the original King Sombra.
On March 15, 2015, prior to Sombra's reformation in the comics, Jim Miller was asked, "I would like your thoughts on this: are Sombra and Tirek the redeemable types? This is not about Season 5 at all[,]" and replied, "I don't want to speculate in case we ever decide to use them again." On April 1, 2015, the release date of My Little Pony: FIENDship is Magic Issue #1, Jeremy Whitley stated regarding Sombra's FIENDship is Magic Issue 1-established backstory, "Well, as show has made it clear it will not deal with Sombra, there is no reason to worry it will be contradicted." A cut scene from Slice of Life would have featured Sombra inexplicably appearing and getting into a musical duel with Octavia Melody, inspired by "The Devil Went Down to Georgia." 
According to Twitter conversations with Jim Miller in early October 2016, late February 2018, and mid-April 2018, he might not reprise his performance as Sombra if the character ever has further voiced dialogue. Alvin Sanders replaced Miller as the voice of Sombra in season nine. As such, Sombra's voice in season nine is different than his voice in season three. Jim Miller explained that when he voiced Sombra in season three, he was in a disembodied state while Alvin's voice for Sombra in season nine is his true fully-formed voice.
Depiction in the series
King Sombra first appears in the season three premiere The Crystal Empire - Part 1. Princess Celestia describes him at the beginning of the episode as "a unicorn whose heart was black as night" and took over the Crystal Empire. In a flashback, Sombra looks down gleefully from his castle at a chain-gang of Crystal Ponies, when two silhouettes of Princess Celestia and Princess Luna shoot a beam at him that turns him to "shadow" and banishes him to "the ice of the arctic north." Celestia says he was able to put a curse on the empire as he was imprisoned, which caused it to "vanish into thin air". Celestia demonstrates that if the empire is filled with hope and love, then those emotions will be reflected across all of Equestria, but if hatred and fear take over the Crystal Empire, black crystals sprout from the ground. When Celestia creates the crystals, her horn is engulfed in black mist and her eyes glow green and emanate the purple smoky trail the same way Sombra's eyes do, implying that she may have knowledge of his magic.
Twilight Sparkle and her friends travel to the Crystal Empire to defend it under the order of Princess Celestia. When they arrive in the frozen north of Equestria, they meet with Shining Armor on the outskirts of the Crystal Empire. Sombra rises as a cloud of black smoke behind them and pursues them through the snow. Shining Armor confronts Sombra and shoots a beam at him, which Sombra evades and lets the beam pass through the black cloud. Sombra then charges at Shining Armor, and the scene cuts right before they clash. Twilight and her friends pass safely through the barrier and arrive in the Crystal Empire, soon followed by Shining Armor, whose horn is now encrusted with black crystals which prevent him from using magic. When they meet Princess Cadance, Shining Armor explains that Cadance is using her magic to "spread love and light" to protect the Crystal Empire and that King Sombra countered Shining Armor's protection spell.
Later in the episode, Twilight and her friends interview some Crystal Ponies. One pony whom Twilight interviews tells her that she can't seem to remember anything before King Sombra came to power and flinches while a superimposed image of King Sombra's eyes flashes over her. She then says she doesn't want to remember anything about his rule.
When Cadance's magical barrier starts to fade, Sombra approaches the barrier, but his horn is sheared off as the barrier rises again. It falls to the ground and transforms into a black crystal which embeds itself in the ground and begins spreading to the crystal gates of the Empire.
Twilight performs "a little trick Celestia taught [her]", which gives her the same green glowing eyes and horn engulfed in black mist as Celestia did at the beginning of the story. She turns the throne black with this spell, and slowly makes the throne room look the way it did when King Sombra ruled. She finds a hidden staircase, and at its bottom is "a doorway that leads to your worst fear", created by "King Sombra's dark magic". When Twilight is under the spell, she has the same green eyes as Sombra; Spike wakes her from this state, but then he falls into it himself and his eyes change the same way, and Twilight wakes him in turn.
Eventually, Twilight and Spike find the Crystal Heart, but Sombra, able to invade once Cadance is no longer able to perform her spell, traps Twilight in a ring of black crystals to prevent her from using the heart. Twilight tells Spike to take the Crystal Heart to Cadance. At first Sombra advances as a pillar of black smoke, and he materializes as his unicorn self at the end of it. Right as he's about to take the Crystal Heart from Spike while standing upon a growing, menacing shard of his own crystals, Cadance, propelled by Shining Armor, snatches Spike and the Crystal Heart before he can reach them. With the return of the Crystal Heart and Cadance saying "Use the light and love within you to ensure that King Sombra does not [return]", the Crystal Empire is restored to its former glory and Sombra, much to his horror, shatters to pieces in a flash of light, along with his crystals, and his remaining smoke dissipates.
In The Cutie Re-Mark - Part 1, due to Starlight Glimmer altering history, she inadvertently creates an alternate future where Sombra—unopposed by the Mane Six and Spike—has successfully reclaimed the Crystal Empire and conquered half of Equestria. He is seen commanding an army of Crystal Ponies under his control in a war against Princess Celestia.
In the season six premiere, Spike mentions King Sombra while telling the Crystal Ponies about how he was defeated. Later, Twilight Sparkle mentions that the reason King Sombra merely hid the Crystal Heart rather than getting rid of it was to stop the Frozen North's weather from breaching the empire.
King Sombra is mentioned by Pinkie Pie in Shadow Play - Part 2.
In the season nine premiere The Beginning of the End - Part 1, King Sombra is restored by Grogar to join him in an alliance with Queen Chrysalis, Lord Tirek, and Cozy Glow to take over Equestria. Uninterested in allying with his fellow villains, Sombra sets out on his own to retake the Crystal Empire by himself. He is successful in single-handedly storming the city, enslaving its citizens, and imprisoning the royal family, but the Mane Six defeat him with the Elements of Harmony just as quickly, seemingly vaporizing Sombra. After the Mane Six return the Elements to the Tree of Harmony, however, Sombra reappears and destroys the tree along with the Elements, having faked his earlier defeat to remove the source of the Mane Six's power.
In Part 2, Sombra proceeds to attack Ponyville, brainwashing its citizens into helping him lay siege to Canterlot Castle, which he easily seizes control of upon finding it unattended by Princess Celestia and Princess Luna. However, he is opposed yet again by the Mane Six alongside Discord, who pretends to be injured by Sombra's magic to spur his friends into action. Realizing that they still embody the spirit of the Elements without wielding the artifacts, the Mane Six combine their magic and destroy Sombra for a second time. Observing this from his crystal ball, Grogar shows Sombra's demise to the other villains as a warning of what could happen to them if they do not unite against the Mane Six.
King Sombra is mentioned in Uprooted, Sparkle's Seven, She's All Yak, and The Last Crusade. In The Ending of the End - Part 1, it is revealed that Grogar was Discord in disguise all along and restored Sombra in an attempt to boost Twilight's self-confidence as Equestria's future ruler. In Part 2, Twilight has a photo of Sombra pinned on a thought chart along with pictures of the other villains.
Twilight Sparkle says that King Sombra uses dark magic. He can generate black crystals that function as weapons and neutralize magic, and he can turn his body to shadow to dodge attacks and travel large distances. He is also powerful enough to cast a curse to make the Crystal Empire disappear.
In The Beginning of the End, Sombra demonstrates the ability to subjugate ponies into doing his bidding with his gaze, as well as show ponies their greatest fear. He can also conjure helmets (which serve the same function as his mind-controlling gaze) from out of thin air.
Depiction in comics
The Midtown Comics cover variant of My Little Pony: Friendship is Magic Issue #4 and Issue #5 are two halves that when put together feature King Sombra's eyes in the background. Covers A, B and the Hot Topic variant of Issue #18 and cover A of Issue #19 feature King Sombra as well.
He appears at the end of My Little Pony: Friendship is Magic Issue #17 emerging from a magical mirror, his figure covered in shadows and his eyes glowing green. In Issue #18, Princess Celestia talks about the King Sombra of another world she'd visited, where he rules Equestria with kindness and benevolence. This Sombra is revealed to be in love with Celestia, who loves him in return. In Issue #19, the original King Sombra is shown in a stained glass window and in Twilight Sparkle's memory of his defeat. The alternate universe King Sombra makes plans with the Mane Six on how to stop the alternate Princess Celestia and Princess Luna. In Issue #20, the alternate Sombra and the Mane Six go to the Castle of the Two Sisters and enact their plan to defeat the evil Celestia and Luna. Upon realizing their plan will imprison the good Celestia too, Sombra uses the Elements of Harmony to absorb the alternate princesses' evil and becomes just like the original King Sombra, disappearing immediately afterward. In the end, he is shown thinking of Princess Celestia and crying, indicating that a part of him still misses her.
King Sombra is mentioned by Shining Armor and the crystal bard in My Little Pony: Friends Forever Issue #4 and appears in a flashback showing how he captured the bard with the assistance of his guards. Sombra is also mentioned in Issue #14.
In a flashback detailed in My Little Pony: FIENDship is Magic Issue #1, Sombra is found as a colt in the wasteland of the arctic north and brought to a Crystal Empire orphanage. He could only speak one word - "Sombra" - so it became his name. During his time at the orphanage, Sombra was teased by other foals, but he made a close friend named Radiant Hope. Every year during the Crystal Faire, Sombra suffers severe aches. In one particularly painful year, his unicorn body would have crumbled to pieces if not for Radiant Hope's healing magic.
When he runs off into the frozen wastes one day, Sombra finds a strange red crystal. Calling itself his mother, the crystal reveals to Sombra his true nature: he is actually a living shadow called an "umbrum," created to destroy the Crystal Heart and set free the umbrum army trapped below the Crystal Empire. With his dormant powers awakened, Sombra embraces his destiny; he steals the Crystal Heart away, turns the empire's ruler Princess Amore into a crystal statue, and shatters the statue to pieces. When Radiant Hope informs Princess Celestia and Princess Luna, Sombra realizes his defeat is imminent, so he enacts a curse that makes the Crystal Empire vanish.
Back in present day, Sombra's disembodied horn makes its way to the bottom of the spiral staircase, appearing to still contain his essence. In My Little Pony: Friendship is Magic Issue #34, Radiant Hope uses her healing magic on Sombra's horn to completely restore his body. In Issue #35, he frees the villains that Hope gathered, and he is soon forced to battle Celestia and Luna once more, eventually turning them to stone. In Issue #36, Sombra makes plans to release the umbrum army beneath the Empire, briefly putting him at odds with Queen Chrysalis. By the end of the issue, he releases the umbrum from their prison after Twilight's intervention results in Radiant Hope getting injured.
In Issue #37, Sombra declares himself emperor and prepares to invade the rest of Equestria, but Hope's words about choosing one's own destiny deeply affect him. After a change of heart, he saves the Crystal Empire from the umbrum, and Hope and the princesses use their magic to turn him into a real unicorn. In the end, Sombra sets out with Hope to find the fragments of Princess Amore's statue and restore her.
Sombra is mentioned again by Prince Blueblood on My Little Pony: Friends Forever Issue #26 page 5, and he appears on My Little Pony: Friendship is Magic Issue #68 page 8. Of My Little Pony: Nightmare Knights Issue #1, he appears on a playing card on cover RI, and his Reflections self in Princess Eris' casino on page 12 and Issue #2 page 20.
King Sombra serves as the main antagonist in My Little Pony/Transformers II. After losing his physical form in The Beginning of the End - Part 2 and reconstituting himself in an immobile crystal form, he is discovered by the Decepticons in Issue #1 and absorbs some of Twilight Sparkle's magic, allowing him to gain a physical body again. He puts some of the Mane Six, including Twilight, and the Decepticons, including Megatron, under his mind control and sets out to conquer the planet Cybertron.
Series 2 of Enterplay's trading cards includes a card featuring King Sombra, #28. Both sides of the card list his name with a trademark symbol, and the back of the card includes the description "After being turned to shadow and banished to the frozen north for 1,000 years, this black-hearted unicorn is back for revenge! The mere mention of King Sombra's name strikes fear into the hearts of ponies all across the Crystal Empire, and it's easy to see why! Sombra recently returned, only to be defeated again by Princess Cadance and the Power of the Crystal Heart. Some say that his horn survived his defeat, but only time will tell if he will ever return."
Sombra also appears on the WeLoveFine T-shirts "Minimal Sombra", "Sombra's Wrath", "King Sombrero", "RD Big Adventure", "Sombra Crystal Silhouette", and "Mythical Sombra", and is shown on Acidfree's first art print.
King Sombra first appeared on Hasbro's Pony Wedding microsite, which has been accessible since July 2012, before any information about the character was released publicly. The quiz does not refer to him by name. In the microsite's Wedding Quiz section, the quiz "Your dream wedding location!" includes the question "Who should be the MC?", with Sombra as the choice that steers the quiz's result to the Crystal Empire.
King Sombra is included in Hasbro's online game Crystal Empire Seek & Find as one of the items in level 5.
In the HubNetwork game Adventure Ponies 2, King Sombra is the first boss.
Discovery Family description
He's only the scariest pony ever -- he can even appear as black smoke. King Sombra enslaved the Crystal Ponies, and when Princesses Celestia and Luna banished him, he made the Crystal Empire disappear. The ponies used the Crystal Heart, plus the power of love, to restore the Empire -- and shatter this evil Unicorn forever.[sic][note 1]
The Elements of Harmony guidebook
KING SOMBRA ruled the Crystal Empire thousands of years ago but was banished and turned to shadow. Before he disappeared, the snarling black-hearted monster made the kingdom disappear and destroyed hope and love in the process. He recently returned but was thwarted by Twilight Sparkle and her pony friends.
In the My Little Pony Equestria Girls screenplay novelization My Little Pony: Equestria Girls: Through the Mirror, chapter 3's narration states that without Twilight Sparkle's Element of Harmony crown, "everypony back home in Ponyville and everypony else in the Kingdom was left completely vulnerable. What if Queen Chrysalis somehow came back again? Or King Sombra? Or somepony even worse? It was a horrible thought."
King Sombra appears in the picture book Good Night, Baby Flurry Heart, in which he appears as a giant pony in the story Shining Armor tells to his daughter Flurry Heart.
King Sombra appears in episode 5 of Baby Flurry Heart's Heartfelt Scrapbook, "Saving the Crystal Empire".
King Sombra, another King Sombra, and Sombra are characters in Gameloft's mobile game. King Sombra's in-game descriptions each state, "The former tyrant ruler of the Crystal Empire, King Sombra is one unnerving unicorn! With his powerful dark magic, piercing green eyes and crazy laughter, this shadowy shadow dweller is the stuff nightmares are made of!" Sombra's in-game description states, "Note the lack of 'King' before his name. This dethroned despot may have a second chance to be the good pony his best friend always knew he could be... Will he take it?" Sombra's outfit can be changed to appear as either the redeemed Sombra, or as his counterpart from Reflections, and has a story role in the event based on the latter. He also has a prominent role in the "Siege of the Crystal Empire" story event, which includes him fighting the Umbrum rather than simply banishing them using the Crystal Heart.
King Sombra is described by Princess Celestia as a unicorn whose heart is "black as night". In person, King Sombra is sadistic, fierce, and cruel to the point of addressing the Crystal Ponies as his "crystal slaves" and appearing to delight in their misery. Though untalkative, he is desperate to retake the Crystal Empire and relentless towards that end. He chases Shining Armor and the Mane Six during their first encounter, ultimately lays a curse on the former, and later races Spike in an attempt to regain the Crystal Heart.
Sombra is much more talkative in The Beginning of the End - Part 1 and Part 2, in which he is depicted as being pompous, self-centered, and arrogant (to the point of having the brainwashed Cakes make him a fruitcake congratulating him on his victory). He believes with full confidence that no one (not even Discord) can overcome his power, that he alone is capable of conquering Equestria, and that he has no need for allies. As such, he is dangerously overconfident and convinced that the Mane Six are no threat to him without the Elements of Harmony. When the Mane Six use the magic of friendship to overpower him, he breaks down, desperately denying his impending defeat.
In My Little Pony: Friendship is Magic Issue #18, a parallel version of King Sombra in another world is stated by Celestia to rule that world's Equestria with "kindness and benevolence", as opposed to the King Sombra seen in the series. In his introduction, he is generally very kind and polite. He is also quite dashing and charming, as evidenced by Rarity and Fluttershy swooning over him. The alternate Sombra is later revealed to be deeply in love with Celestia, who reciprocates his feelings.
This Sombra also has a humble side, considering himself a normal pony who is also a king, shown when he has a heart-to-heart with Twilight Sparkle, helping her in her doubts of being a princess. Unlike the original, this King Sombra is selfless, as he gives up himself to evil to spare the good Celestia and restore balance to both their worlds, even if it means never seeing the pony he loves again. Even after being taken by evil he mourns his beloved Celestia, now lost to him, possibly forever.
In My Little Pony: FIENDship is Magic Issue #1, Sombra is shown to have been friendly, caring, and shy during his youth. However, after learning about his origin, he becomes evil and power-mad, referring to himself as the "king of all monsters."
In Siege of the Crystal Empire, Sombra holds a grudge toward Radiant Hope for her apparent betrayal and the princesses for his imprisonment, and he bears a great deal of self-consciousness in regard to his true nature. However, he still cares deeply for Hope, demonstrated by his concern for her well-being. Sombra also develops an imperious attitude, referring to Queen Chrysalis as a "queen of vermin".
