Lord Tirek

Lord Tirek is a male centaur, the older brother of Scorpan, and the main antagonist of the season four finale. He is a villain who escapes from Tartarus, steals magic, and seeks to rule over Equestria.

Tirek is defeated and banished back to Tartarus by the Mane Six through Rainbow Power magic acquired from the Chest of Harmony. He is later released from his imprisonment by Grogar to join his alliance, along with King Sombra, Queen Chrysalis, and Cozy Glow, to defeat Twilight and her friends and conquer Equestria.

Development and design
Tirek shares his name and certain aspects of his design with a Generation 1 villain from the animated television special Rescue at Midnight Castle; he was redesigned by Jeremy Tin for the current Generation 4. He is a centaur with red skin, white hair, dark fur, black horns, and cloven hooves. His head has bull-like facial features with a goat-like beard. DHX Media designer Phil Caesar strove to make Tirek "as scary as [he] can", receiving input from his 10-year-old daughter on whether each design was "too scary" or "not scary enough". According to Hasbro developer Brian Lenard, Tirek was originally designed with an "almost entirely red" body, but was recolored with a black torso to "tone down the intensity" and give more focus to the expressions of Tirek's face and arms.

Over the course of Tirek's appearances in the finale, his appearance gradually changes as he absorbs more magic. He initially appears very frail, with muted colors and a hunched posture that leaves him roughly at the height of a normal pony. After absorbing the magic of many unicorns, he gains a more muscular physique, brighter colors, and a pair of curved horns. His later transformations increase his size and makes him brawnier, and with increasingly long and elaborate horns.

During her May 2014 takeover of the Hub Network's Twitter feed, Meghan McCarthy identified Tirek as her "new favorite character," and described Tirek as having "some serious issues and some serious magic." On May 10, 2014, Jayson Thiessen tweeted "hehe" in reply to a fan's tweet "Was just rewatching episodes with a friend. Was that Tirek at the end of Castle Mane-ia? My mind may have just blown." In a series of tweets during January 2015, Joshua Jackson replied to Jim Miller "Was that Tirek's shadow at the end of Castle Mane-ia?" "I don't really think it is, but I'd like to hear from someone on the team." "Or, I think it's up to me to decide huh? :)," Miller replied "You got it!" Jackson further replied "I got what?" "I got what exactly?" "Here's a compaison [sic] of The Pony of Shadows and Tirek pic.twitter.com/UxTgEUfnkg," and Miller further replied "you got that it's up to you to decide." On March 15, 2015, 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."

Season four
Lord Tirek appears in Twilight's Kingdom - Part 1 in a frail and weakened state, indicated by pale colors and a raspy voice. In a Canterlot alleyway,  he approaches the unsuspecting unicorn Rare Find and drains his magic, growing larger and more powerful. Princess Celestia senses this attack in a vision in her dream, causing Princess Luna to see it and become aware as well.

Celestia and Luna explain to Twilight Sparkle that Tirek and his brother Scorpan came to Equestria from "a distant land" to steal Equestrian magic. However, Scorpan grew to appreciate the ways of Equestria and even befriended a young unicorn wizard. Scorpan pleaded with his brother to abandon their plans, but Tirek refused to relent. To save Equestria, Scorpan informed the princesses of Tirek's intentions. Scorpan returned to his homeland while Tirek was imprisoned in Tartarus for his crimes.

Celestia states that Tirek likely escaped during the events of It's About Time, when Cerberus left his post at Tartarus' gates, and has only recently regained enough strength to use his dark powers after languishing in Tartarus for centuries.

While continuing to devour unicorn magic, Tirek is captured by Discord, who is there on behalf of his friendship to the ponies. Likening Discord's actions to those of his "weak-minded" brother, Tirek appeals to Discord's former nature as a master of chaos, convincing him that friendship is "a new form of imprisonment" and that betraying the ponies will grant him freedom to do as he pleases. With Discord's aid, Tirek continues absorbing unicorn magic, becoming larger and stronger, and increasing in power. He soon becomes strong enough to begin absorbing magic from Pegasi and Earth ponies as well.

In Twilight's Kingdom - Part 2, Tirek continues to grow in strength and size. He becomes powerful enough to steal Alicorn magic and makes his way to Canterlot Castle. Anticipating his arrival, Celestia, Luna, and Cadance transfer all of their magic into Twilight and send her into hiding, believing Tirek is unaware of her royal status. When Tirek arrives and finds the princesses devoid of their magic, he banishes them to Tartarus as revenge for his own imprisonment.

When Discord has doubts about their alliance, Tirek gives him the medallion he wears around his neck as a token of his gratitude and loyalty, claiming that it originally belonged to "someone very close to" him. He soon discovers Twilight via her depiction in a stained glass window and questions the existence of a fourth princess; Discord confirms this and directs Tirek to Twilight's home in Ponyville.

When the two arrive, they capture Twilight's friends and Tirek absorbs their magic, growing even more powerful. The prospect of ruling Equestria alongside Tirek thrills Discord, but Tirek suddenly turns on him and says he is no longer of any use, proceeding to absorb his magic as well. When Discord reminds Tirek of the medallion, Tirek reveals it was given to him by his treacherous brother Scorpan and considers it "as worthless as he is."

Tirek soon finds Twilight and pursues her relentlessly, destroying the Golden Oak Library in the process. Enraged, Twilight fights Tirek in an intense battle of magic. Tirek fights back, but their evenly matched might leads them to a stalemate. Thus Tirek offers Twilight a trade: the release of her friends in exchange for the Alicorn magic. Despite her friends' protests, Twilight agrees to trade the magic for her friends, including Discord despite his betrayal. Upon releasing them, Tirek promptly absorbs all of Twilight's magic, making him all-powerful.

However, when Discord bestows Scorpan's medallion upon Twilight as a sign of true friendship and gratitude, it proves to be the final key needed to open the Tree of Harmony chest. As Tirek rampages through the Everfree Forest, the Mane Six open the chest, gaining a new, powerful magic that Tirek is unable to overpower. With this magic, the ponies strip Tirek of all his stolen magic and reduce him to his weakened state again. He last appears locked in a cage within Tartarus, guarded by Cerberus.

Season five

Pipsqueak mentions Lord Tirek in Crusaders of the Lost Mark, stating that Tirek's battle with Twilight is the cause of the poor condition of the schoolyard.

In The Cutie Re-Mark - Part 2, Tirek appears laying waste to Equestria in one of the alternate timelines created by Starlight Glimmer.

Season seven
Lord Tirek is mentioned in Shadow Play - Part 2.

Season eight
In School Raze - Part 1, the Mane Six visit Tirek in his Tartarus prison and accuse him of stealing the magic of Equestria again. Tirek denies this but reveals that he conspired with Cozy Glow to drain Equestria of its magic in order to get his revenge on the ponies who defeated him. In Part 2, Tirek realizes the ponies being trapped in Tartarus means he would be trapped together with them for eternity, and he agrees to help them escape after Pinkie Pie almost drives him insane with her clownish antics. After Cozy Glow's plans are foiled, she is imprisoned in Tartarus for her crimes, and she tries to make friends with him.

Season nine
In The Beginning of the End - Part 1, Tirek suffers from Cozy Glow's repeated attempts to befriend him while imprisoned. Grogar suddenly transports the two from their cages to his lair to join forces with him, Queen Chrysalis, and King Sombra against the Mane Six. As a demonstration of his power, Grogar feeds Tirek with a sample of magic that rejuvenates him into a slightly younger form. In Part 2, Tirek struggles to work together with his fellow villains until Grogar shows them the Mane Six destroying Sombra, who had earlier left the group to conquer Equestria on his own. Under the threat of meeting the same fate, Tirek and the others reluctantly submit to Grogar's will.

Personality
Tirek is evil, domineering, narcissistic, and driven by an obsessive desire for power, believing that all the magic of Equestria should be his. He has a violent temper and fierce nature, which he directs towards Twilight Sparkle and the other princesses. He is also very manipulative and highly persuasive when striking a deal. However, while Tirek may hold up his end of a bargain in some cases, he is generally dishonest and traitorous, not hesitating to turn on and dispose of anyone whose usefulness has expired, such as Discord.

He harbors a deep resentment toward his brother Scorpan after his betrayal, describing him as "weak-minded" and "worthless."

Tirek holds a very low opinion of the concept of friendship, believing it to be both a sign of weakness and a form of imprisonment. However, he conspires with Cozy Glow for the sake of realizing his goal of revenge, even referring to her as his "little protégé".

Magic
Tirek is potentially one of the most powerful magic users in the show. However, his magic severely diminishes due to his imprisonment in Tartarus. He frequently shoots beams from an orange orb floating between his horns, and he absorbs magic from others.

Upon escaping from Tartarus, he steals unicorns' magic to restore his strength, later stealing it from Pegasi, Earth ponies, and even Discord himself. Tirek changes both physically and magically, gaining brighter colors, a more muscular physique, longer horns, and a deeper voice. As he progresses, he drains magic from dozens of ponies at once.

After absorbing the magic of Twilight's friends and Discord, Tirek's size increases to the point at which he towers over most buildings in Ponyville. His growing musculature shatters the bracers on his arms, and he grows a mass of white hair on his head to match his beard and tail. At this level of power, he matches Twilight Sparkle in a magic battle when she is imbued with the power of all four Alicorn princesses in Equestria. When negotiating with Twilight, he snaps his fingers and summons Twilight's drained friends in levitating bubbles.

After absorbing Twilight's Alicorn magic, Tirek grows even larger. The Mane Six finally overpower him when they gain the power of the Tree of Harmony, and he loses all of the magic he had drained from his victims.
