My Little Pony Royal Wedding The Movie

Plot
Twilight reads part of the invitation Spike delivers a letter from Princess Celestia to Twilight Sparkle, Fluttershy, Rainbow Dash, Rarity, Pinkie Pie and Applejack. In the letter, Princess Celestia asks Twilight and her friends to help with the upcoming royal wedding in Canterlot. Applejack will provide catering for the reception, Pinkie Pie will host it, Fluttershy will train and conduct the bird choir, Rainbow Dash will perform a sonic rainboom during the ceremony, and Rarity will design the wedding dresses. Twilight receives the keystone job of overseeing the preparations. Twilight is shocked to learn that the bride and groom are "Princess Mi Amore Cadenza" and Twilight's brother, Shining Armor. Twilight is upset because he never told her about his wedding or Princess Mi Amore Cadenza. In a song called B.B.B.F.F. ("Big Brother Best Friend Forever"), Twilight recalls how she and Shining Armor used to do everything together, and how much she misses him. On the train ride to Canterlot, everyone except Twilight happily discusses the wedding, and only Applejack notices Twilight's glumness. Upon inquiry, Twilight says that she is still thinking about Shining Armor's neglect of her, though Applejack tells her not to worry. "Hey. You're my little sister."At Canterlot, it is evident that there has been an increase in security: the train passes through a pink protective sphere encasing the city, there are many guards at the station, and Princess Celestia keeps watch with the aid of a telescope from the balcony of the highest tower. Shining Armor is happy to see his sister and affectionately calls her "Twily.” Twilight immediately berates him for not telling her about the wedding, but Shining Armor explains that he had no choice and Princess Celestia wanted an increase in security in response to an exterior threat. Twilight concedes but remains hurt. Shining Armor reassures her that she has always been, and always will be, important to him, and asks her to be his Best Mare. Shining Armor explains that Princess Mi Amore Cadenza is the full name of Cadance, Twilight's former foalsitter. Twilight proclaims her to be "beautiful, caring, and kind" and "the best foalsitter ever.” A flashback shows that filly Twilight and Cadance used to frolic in the park, play on the swings, and resolve lovers' quarrels. Twilight remembers their chant: Sunshine, sunshine, ladybugs awake! Clap your hooves and do a little shake!" Green magic from a pink pony? Suspicious. Twilight begins overseeing the wedding preparations, starting in Applejack's kitchen. When Cadance shows up to check the catering, Applejack offers her an apple fritter, which Cadance insincerely calls "delicious.” Applejack gives Cadance a bag of fritters in case she forgets to stop for a meal, but when Applejack turns around, Cadance tosses the fritters into the trash. Twilight, incensed by Cadance's ingratitude, visits Rarity, who is working in the tower room she stayed at in Sweet and Elite. Twilight begins to describe Cadance's temperamental behavior, but Cadance arrives with her bridesmaids, (Lyra Heartstrings, Minuette, and Twinkleshine). Cadance ignores Rarity’s greeting and appraises her dress. She says that she was hoping for more beading and a longer train, and turns her attention to the bridesmaids' dresses. Displeased, she demands that Rarity make them in a different color, despite the fact that her bridesmaids love their dresses. Rarity is more than happy to comply with the royal demands, but Twilight calls Cadance "Princess Demandypants" when Cadance is out of earshot. After nightfall, Cadance meets Pinkie Pie inside the castle ballroom. Pinkie presents her flamboyant reception plans, which include a board game, carnival music, and dancing. Cadance compares the setup to a "party for a six-year old,” although Pinkie Pie is oblivious to the insult. Meanwhile, Twilight has been eavesdropping on their exchange. Maybe there shouldn't even be a wedding!" Princess Luna enters the shield and switches places with Princess Celestia on the tower balcony for the night. Meanwhile, the six friends and Spike are sipping drinks after a day of work. Twilight seizes the opportunity to find fault with Cadance, calling her the "absolute worst bride-to-be, ever.” However, her friends rationalize Cadance's behavior. Fluttershy mentions that Cadance criticized one of the choir birds during rehearsal, but the bird in question was off-key. The friends suggest that Twilight is still being excessively protective of her brother, but Twilight insists that her friends are too preoccupied with wedding preparations to notice Cadance's attitude. Frustrated, she storms off. Cadance using her magic on Shining Armor apparently to heal his migraine. Twilight visits her brother's house and tries to talk to him privately, but is interrupted by Cadance, who is also intent on speaking with him. Twilight watches Cadance scold Shining Armor about a crest he is planning to wear with his dress uniform, which belonged to his favorite uncle. Shining Armor protests and Cadance swiftly casts a spell on him, making him to go wall-eyed. Frightened, Twilight runs away. Shining Armor sees Twilight running off and wonders what she wanted to tell him After a short recap of the events from the first part, Princess Cadance’s imposter has trapped Twilight Sparkle in the caves beneath Canterlot. The image of her false form appears on the crystal walls, and she hints at her plans for Shining Armor and taunts Twilight. Twilight shoots magic at the cackling reflections, and blasts away a wall to reveal the real Princess Cadance, startled and disheveled. Twilight quickly has Cadance at her mercy, believing her to be the imposter. Cadance pleads with her, telling her that she had also been imprisoned inside the cave, but Twilight doesn't believe her. Cadance finally recites a rhyme she had taught Twilight as her foal-sitter, which Twilight remembers. Twilight's suspicions are banished, and the two embrace. In the song This Day Aria, Part 1, Cadance's imposter sings about how her plans will come to fruition as she prepares for the wedding in Canterlot, and the real Cadance sings about her determination to save her fiancé as she and Twilight try to find a way out of the crystal caves. A camera pan shows that Cadance and Twilight are beneath the hall where the wedding ceremony is starting. Twilight teleports herself and Cadance to the cave’s exit, but they are confronted by the bridesmaids: Minuette, Lyra Heartstrings, and Twinkleshine. The camera cuts to the wedding hall. Celestia is about to pronounce the couple mare and colt when Twilight and Cadance burst in. A flashback reveals that Cadance and Twilight distracted the bewitched bridesmaids with a bouquet of flowers before escaping from the cave. She declares the imposter to be a changeling, a creature that takes the form of a loved one and gains power by feeding off of love. The imposter, enraged, reveals her true form: Chrysalis, Queen of the Changelings. Chrysalis says that Equestria has more love than any place she’s ever encountered, and conquering Equestria will give her and her Changeling army more power than they've ever dreamed of. Even as she speaks, the changeling army is battering away at Canterlot’s defenses. Princess Celestia, infuriated at having been deceived, declares that even though Shining Armor is powerless, she will defend her subjects. She fires a white-golden beam of magic at Chrysalis, who retaliates with a green beam of magic. Chrysalis's beam overpowers Celestia's, smacking Celestia to the floor, knocking off her tiara, causing her mane and tail to stop flowing, and scorching her horn. Chrysalis is astonished by the power she has gained from Shining Armor's love. Struggling to remain conscious, Celestia instructs the six main characters to retrieve the Elements of Harmony, their only hope for stopping Chrysalis, sounding like she wants them to use them to kick Chrysalis' flank. The six ponies race towards Canterlot Tower where the elements are held. The changelings finally shatter the protective sphere and start wreaking havoc in the city. The six ponies are hemmed in by a crowd of hungry, vicious changelings, which take on the appearance of the six. Using everything from their hooves to Pinkie Pie’s party cannon, the six ponies defeat the first wave of changelings. However, their reprieve is short; Canterlot Tower has already been overrun by more changelings. With the numbers stacked heavily against the main six, they are soon captured. The power of love The changelings have imprisoned Celestia in a lime green goo cocoon in the wedding hall and glued Cadance’s hooves to the floor with the same substance. Cadance insists that the six friends will save them, but a group of Changelings walk in with the friends held in custody. Chrysalis gloats that everyone but Twilight was too fixated on the wedding to notice anything. Applejack apologizes on behalf of the others for ignoring Twilight’s doubts, and Twilight assures Applejack that she has no hard feelings. Chrysalis sings a stanza to the tune of This Day Aria as she observes the chaos in the streets below. Twilight frees Cadance and urges her to try and break the spell on Shining Armor. Cadance embraces him and breaks his trance with her spell of love. Shining Armor says that he doesn’t have the strength to repel the changelings, but Cadance declares that her love will give him strength. The two connect horns, creating a powerful, bright pink, purple and white whirlwind of magic that lifts the couple into the air and shakes the room. When they look into each other's eyes, their bodies glow with bright white light and take on a heart shape as the magic expands outward as a bright, purple sphere. The ponies shade their eyes from the light, while Chrysalis and the changelings are thrown out of Canterlot. With the changelings gone, and Celestia free from her cocoon, the ponies prepare for the real royal wedding. At the wedding, Twilight takes her reinstated place as best mare as their parents look on proudly from the audience. Celestia pronounces Cadance and Shining Armor mare and colt, and levitates their rings onto their horns. Celestia commends the heroism of Twilight and her friends and emphasizes the importance of trusting one's instincts. The bride and groom step out to a balcony to wave to a crowd of cheering ponies. As Shining Armor and Cadance kiss, Celestia reminds Rainbow Dash to perform her sonic rainboom for the ceremony. The scene changes to the evening wedding reception in the courtyard, where the newlyweds start dancing. Princess Luna joins her sister and the Mane Six and unknowingly asks if she “missed anything”. DJ Pon-3 works her turntables and Twilight sings Love Is In Bloom while a montage of humorous and memorable photos taken during the party is shown. At the end of the party, Shining Armor thanks Twilight and they hug. Before departing, Cadance tosses her bouquet to the onlookers, which Rarity, in a screaming fit, snatches from the other bridesmaids. Twilight and her friends happily watch the royal carriage depart, and Spike unknowingly humors them by saying that he has even better plans for the bachelor party. The movie ends as fireworks light the sky above Canterlot.
