The Wonderbolts' costumes were designed by Lauren Faust's husband and creator of The Powerpuff Girls (1998), Craig McCracken.

Andrea Libman does Fluttershy's singing voice, but not Pinkie Pie's. She stated the reason is because Pinkie Pie's high pitched voice tends to be a strain and that singing with it really hurts her throat. The singing voice actress for Pinkie Pie is Shannon Chan-Kent. Andrea made an exception to not singing as Pinkie at the MLP Fair and Convention on June 25, 2015, when she sang for a fan's birthday, and a Netflix exclusive short where she and Pinkie Pie sing Happy Birthday.

One regular background character pony with an hourglass cutie mark was noted by fans to have a distinctive resemblance to David Tennant's version of The Doctor of the British TV series, Doctor Who (2005). As such, he has taken on the fan nickname, Doctor Whooves, and is the subject of numerous fan creations, although his official name in the series is Time Turner. However, Hasbro has released an official figure of the character under the name Dr. Whooves with a collar and tie to accentuate the resemblance to the 10th Doctor. In addition, he appears in at least one variant cover of the official My Little Pony comic book with numerous references to the British series.

Lauren Faust originally wanted to call the villain Nightmare Moon; Discord. But executives from Hasbro decided the name would be too confusing for their target demographic to comprehend. However when pitching for the second season premiere, Hasbro execs had no problem with the name when Executive Producer Lauren Faust mentioned the character was akin to Q from Star Trek: The Next Generation (1987) The comparison led to show producers actively seeking out John de Lancie to voice the character.

The background character Sweetie Drops (also known as Bon Bon) almost always uses a different voice actress every time she has a speaking role for her appearances.

The character of Princess Celestia was originally supposed to be Queen Celestia, but Hasbro executives decided against the title of Queen since Disney had started the trend of animated Queens always being villains (excluding Elsa from Frozen). There later was an evil queen in the Season 2 finale (Queen Chrysalis) and possibly to build on that trend, the following season opened with an evil king (King Sombra).

Applejack is the only main character to remain mostly the same to the character she was based on. The other five main pony characters are all amalgamations of several characters from past generations of the show.

Producer Lauren Faust developed this series with the goal of creating a more sophisticated version of the My Little Pony franchise with more realistic and proactive characters than the usual sexist stereotypes she saw in earlier incarnations. For instance, the insistence on the part of Hasbro executives that clothes and fashion be a part of the characters' interest was addressed by making Rarity obsessed with fashion in the context of being a professional artist and a small business owner with clothes as her preferred medium.

Broke My Little Pony 'n Friends (1986) record of being the longest running My Little Pony TV series. Furthermore, at 100+ episodes, this series is also the longest running individual television series featuring a Hasbro toy property in the company's history.

Twilight Sparkle's appearance is based on a pony character from the first series; Twilight Velvet who makes appearances as Twilight Sparkle's mother.

While the show is labled for younger female audiences many of the jokes and references in the show have adult themes to them. Some include references to alcohol, movies for adults (like The Big Lebowski), and a few references to older bands and music (like Diamond Dogs).

Almost all of the main voice actors have worked on previous versions of My Little Pony.

According to series creator Lauren Faust, the inspiration for Canterlot was the city of Minas Tirith from The Lord of the Rings trilogy.

Rarity was originally planned to represent the Element of 'Inspiration' but producers felt that children wouldn't understand that concept.

Pinkie Pie says her full name is Pinkamena Diane Pie, however Lauren Faust once said that Pinkie may not have been 100% truthful about this.

Rainbow Dash is the only main character to feature a "cutie mark" that is a single symbol. Rarity, Applejack, Fluttershy, and Pinkie Pie all have "cutie marks" that are displayed in a cluster of three. Twilight Sparkle has a huge sparkle surrounded by five little sparkles.

The baby dragon Spike is a reoccurring character that has shown up in almost every televised version of "My Little Pony".

Lauren Faust has said that she always felt that the Cutie Mark Crusaders - Apple Bloom, Scootaloo and Sweetie Belle - should have their own spin-off show aimed at preschoolers - where children learn how to do various activities as the three ponies try them out looking for their Cutie Marks.

All of Applejack's family members are named after apples; Granny Smith, Big Macintosh, Braeburn, Apple Bloom, Pear Butter, Bright Mac, etc.

Princess Luna's name was originally going to be Selena (presumably after the Greek Goddess of the moon, of which Luna is the Roman equivalent). Although her name was changed to legal reasons, she is still referred to as Princess Selena in a novelization of the first episodes.

Some of the cities mentioned in the series are puns: Fillydelphia, Manehattan, Baltimare, Las Pegasus, Saddlarabia, Cloudsdale and Trottingham.

Because of the show's overwhelming popularity, which generates a high volume of fan-related content, the show creators have to do their research to make sure any one of the several pre-existing characters they wish to feature in an episode don't use a name that in any way sounds similar to one created by the fan base.

Fans of the show outside the target demographic are often called "bronies". This is a combination of the words "bro" and "pony".

Background pony Derpy had her eyes fixed and voice changed by Hasbro in a bid to make her seem "less disabled".

Minor recurring villain (and now reformed) Trixie was originally planned to be a boy, until the episode's scriptwriter suggested to Lauren Faust to make the character female. Faust later said that the change was absolutely for the better.

At the end of the episode "The Return of Harmony", a segment is very similar to the end of Star Wars (1977).

The phrase "My little ponies" is used several times to describe secondary characters, the Cutie Mark Crusaders; Apple Bloom, Scootaloo, and Sweetie Belle.

Initial toys for Princess Celestia showed her with a pink coat, rather than white as is in the show. This is apparently due to Hasbro thinking a pink toy would sell better to young girls. Since a canon pink princess character - Cadance - was introduced, toys of Celestia have been released in show-accurate white.

The fan favorite pony, a light grey pegasus mare, with blonde hair and a bunch of bubbles as her cutie mark, has many names. The fan name is Derpy, or Derpy Hooves, but that name was used in the show once, but some people found that name offensive (but derp/derpy means clumsy), so her show name is Ditzy Doo, and more recently named Muffins. But, on merchandise, her cutie mark is either a picture of a muffin, her face, or "Bubbles".

The show has never shown any male alicorns until Big Macintosh became one temporarily in a dream world. All the female alicorns are Celestia, Luna, Cadance, Twilight, and Flurry Heart.

Pinkie Pie's original design was a white Pegasus named and based on Gen 1 pony Surprise, but due to Hasbro no longer having the trademark they changed her to Gen 3 Pinkie Pie colors and name. Later it was decided to move her wings over to Posey-based Fluttershy. Some early show bible images used old concept art for Suprise in Pinkie Pie's colors to represent her.

Tabitha Saint Germain, Ashleigh Ball, Andrea Libman and Cathy Weseluck are all Canadian.

Instead of using words like "God" or "Jesus" in common phrases people use, the characters in the show say "Celestia" instead. Princess Celestia is a bit like a goddess in the show. She uses her magic to raise the Sun and start the day, and has been ruling Equestria for over 1000 years. So it supposedly is more fitting to say that in the show instead.

This show won the 2012 Tubey Awards voter's choice for "Favorite Animated Show" at Television Without Pity, but the staff pick was for South Park (1997).

Although never credited, Lynne Naylor did the final design of Princess Luna/Nightmare Moon.

Rainbow Dash's cutie mark is based on the Symbol of the Gods from the Disney movie Hercules (1997).

Many people believe that Rarity's personality is based off of that of actress Chloë Sevigny.

Spike is the only male main character, yet he is voiced by a woman.

In Season 4, the opening sequence was redone to show Discord in Fluttershy's house. The chaos entity is visible through the far right window of her cottage.

Fans still wonder about Twilight Sparkle's cutie mark. She is the only character with this unique, odd, cutie mark. All other ponies (and zebra), have cutie marks of either one symbol or a group of 3 symbols. Applejack has 3 apples. Rainbow Dash has one "speed" symbol. Twilight Sparkle's cutie mark appears to be a symbol, with 5 stars surrounding it.

Princess Celestia owns a Phoenix called Philomena.

In several episodes, there is a brown male pony with an hourglass for a cutie mark who is believed to be created after the Doctor is Doctor Who. Therefore, the pony's name is Doctor Whooves.

Surnames are not mentioned in this show (with the exception of Pinkie Pie and her sister Maud Pie). Using evidence from her family members, the fan base has declared that Applejack's last name is Apple. While "Dash" and "Sparkle" can be assumed to be the last names of Rainbow Dash and Twilight Sparkle, Tabitha Saint Germain has said in 2018 that Rarity doesn't have a last name. She only has one name, like Cher.

Two actors from My Little Pony: Friendship is Magic have appeared in some version of Star Trek. John de Lancie, who played Q from Star Trek: The Next Generation (1987) voices Discord. William Shatner, who played Captain Kirk in Star Trek (1966) voices Grand Pear. Additionally My Little Pony The Movie 2017 featured Zoe Saldana who appeared in JJ Abrams Star Trek trilogy from 2009-2016.

In one episode of Friendship is Magic, the character Moondancer accidentally calls Twilight Sparkle "Twilight Twinkle" which is a G3 Pony she was based on.

Pinkie Pie is the only character out of the Mane 6 that has had her full name on the show. Her full name is Pinkamena Diane Pie, and lately her sister Maud Pie was mentioned by her full name: Maudileena Daisy Pie.

To watch all 222 22 minute episodes would take 81 hours and 24 minutes.

In "The Cutie Map" (Part 1 & 2), the Staff of Sameness design was based on the Lance of Longinus from the popular 90's anime Neon Genesis Evangelion (1995).

Ever since Starlight Glimmer appeared on the show more frequently, there has been total disagreement between the fans over whether she should be classified as a main character or not. Some fans believe she is, while others still think she isn't because official material/sources do not designate her as such.

The show debuted in 2010 the same year Toy Story 3 (2010) and How To Train Your Dragon (2010) were both released and concluded in 2019 the same year Toy Story 4 (2019) and How To Train Your Dragon: Hidden World (2019) were released.

The Pillars of Equestria say that the six elements are Strength, Bravery, Healing, Beauty, Hope, and Sorcery when compared to the Elements of Harmony: Honesty, Loyalty, Kindness, Generosity, Laughter, and Magic.

On May 1, 2021, it announced that Spike would get his own Spin off Tv Series and a Movie. Featuring Spike, Smolder, Ember, Garble, Mane 6, The Dragon Lord, Princess Celestia, Luna, Candace, and the other dragons. Spike will the friendship lessons with his friends in Dragonland.

As of early Season 8, a few background ponies have appeared in at least 100 episodes, which is more than how many even the Cutie Mark Crusaders appeared in.

Tabitha Saint Germain is the only primary cast member born in the United States, yet she grew up in South Africa and resides in Canada. Tara Strong was born in Canada, yet she is the only primary cast member who resides in the United States.

One of the longest running kid-friendly animated series, running for over 9 years (10 if you count the mini-episodes released in 2020).

Seven episodes of Season 8 were leaked online in December 2017.

The title of Season 6 Episode 5, "Gauntlet of Fire", is likely a pun on Harry Potter and the Goblet of Fire.

Eric Bauza and Patton Oswalt were originally gonna be the voice of Spike the Dragon, Eric Bauza is a Canadian voice actor in the United States like Tara Strong.

Big Mac's catchphrase is "yep", a line said various times by Gary Cooper who was famous for acting in Westerns.

WILHELM SCREAM: the Wilhelm Scream is used a total of 13 times in the series and at least 15 times in the franchise.

CASTLE THUNDER: heard many times throughout the series.

Four of the Mane Six have general American accents: Twilight Sparkle, Pinkie Pie, Fluttershy, and Rainbow Dash. Applejack speaks with a Southern accent, while Rarity has a transatlantic English accent.

This show took longer to premiere in South Korea than Pokemon did - 3 1/2 years against Pokemon's 2 years.

Rainbow Dash is the only member of the Mane 6 who is an only child of her parents. Although Scootalloo acts like a sister to her.

Applejack's parents are Pear Butter and Bright Mac, which were revealed the Season 7 episode, "The Perfect Pear". Lauren Faust admitted that she never gave them any serious thought when creating the show, but has stated that they died when Applejack was a filly (and, presumably, sometime after Apple Bloom was born); it's been also said that they died in a timber wolf attack, though there's no concrete answer to that.

The Pony of Shadows is first mentioned in Season 4 Episode 3, "Castle-Mania". The legend Applejack tells says that when Nightmare Moon was banished, not all of her dark magic went with her, and that remaining magic took the form of the Pony of Shadows. The Pony of Shadows is not mentioned again until the finale of Season 7 more than 3 years later, and his real backstory has nothing to do with Nightmare Moon's banishment.

Rainbow Dash is the last member of the Mane 6 to have a relative(s) shown, her parents are named Bow Hothoof and Windy Whistles.

King Sombra ("The Crystal Empire") is the only villain who dies onscreen in the show's entire run. In My Little Pony: The Movie (2017), the Storm King is the second villain to die onscreen. All other villains on the show are either reformed, redeemed, imprisoned or driven out of Equestria for their crimes.

At the end/beginning of each season, a new villain is introduced with the final exception being Season 9 when the opening conflict is against the long ago defeated King Sombra, and the final showdown was against three more previously defeated villains, Lord Tirek, Queen Chrysalis, and Cozy Glow.

Despite being one of the show's most popular villains, as well as the only original recurring villain left in the show, Queen Chrysalis has only four appearances in the show thus far; all of them are season finales: they include the season 2 finale, "A Canterlot Wedding", in which she makes her debut, the season 5 finale, "The Cutie Re-Mark" and the season 6 finale, "To Where and Back Again"; her fourth appearance in the show was the season 8 episode, "The Mean 6". And now has had four more appearances in Season 9 before her final defeat.

"King Sombra" literally means "King Shadow".
