Examples of The Other Darrin from My Little Pony: Friendship Is Magic
- Spitfire's one line during her debut as an unnamed Wonderbolt in "Sonic Rainboom" is
provided by Nicole Oliver instead of her usual VA Kelly Metzger, who wasn't cast as Spitfire until "The Best Night Ever". - Background ponies generally have different voices from episode to episode, even when they're consistently named (as with Rose, who's been addressed by name in "Bridle Gossip" and "A Friend in Deed"). These voice changes were especially noticeable in the case of Sweetie Drops/Bon Bon; she has had speaking parts in seven different episodes in the early seasons, and her voice had been different all seven times. Once "Slice of Life" aired in Season 5 aired, Andrea Libman voiced her from then on.
- With the exceptions of the Gameloft app, The Hub's commercials for the show itself, and the app's trailer, anything outside of the show that requires voice acting (toy commercials, talking toys, the live show, etc.) and isn't using audio ripped from the show itself doesn't use the original voice actors. Tara Strong has said she'd be more than willing to voice any and all Twilight Sparkle toys, seeing as she's voiced toys before.
- The season 6 premiere had Twilight and Shining Armor's voice actors (Tara Strong and Andrew Francis) also voicing their parents in a cameo. Their expanded roles in the season 7 episode "Once Upon A Zeppelin" have them voiced by Patricia Drake and Charlie Demers.
- Pipsqueak was voiced by William Lawrenson in his first appearance, and Graham Verchere in later appearances.
- Princess Luna in the Japanese dub was voiced by Yumi Uchiyama in the second episode but was voiced by Takako Honda, the voice of Nightmare Moon, in "Luna Eclipsed".
- In the Italian dub:
- Spitfire has three different voice actresses: Debora Morese (Princess Luna and Diamond Tiara) voiced her in "Sonic Rainboom" and "The Best Night Ever", Gea Riva (Silver Spoon, Derpy and Daring Do) took the role in "Hurricane Fluttershy" and Tania De Domenico (Spike) is her current voice since "Wonderbolts Academy".
- Big McIntosh was voiced by Mario Scarabelli up to Season 4, then Diego Baldoin replaced him in Season 5.
- Starlight Glimmer was voiced by Debora Magnaghi in her first appearance, but Beatrice Caggiula replaced her starting from the Season 5 finale.
- In Season 7, Camilla Gallo was replaced as Rarity by Chiara Francese. Camilla Gallo came back in Season 8.
- In Season 8, Tiziana Martello replaces Donatella Fanfani as Pinkie Pie's voice.
- The Romanian dub seemingly changes everyone's voice actor in between seasons. Alina Leonte (Spike) was the only major character who wasn't recast. However; Corina Cernea, Paul Zurbau, Florian Silaghi, Gabriela Codrea, Anca Sigmirean, Sorin Ionescu, and Anda Tămășanu also appeared in all nine seasons. In Season 4, for example, Spitfire was voiced by a man, after being voiced by women in the first 3 seasons.
- And don't forget about the Romanian dubs of Equestria Girls movies which were done in Bucharest by Fast Production Film (instead of Oradean BTI Studio which did the series)
- The Hungarian dub is also a revolving door. Twilight Sparkle, Spike, Apple Bloom, Pinkie Pie, Applejack, and Rainbow Dash are the only main characters who haven't been recast as of season 7.
- Rarity was originally voiced by Andrea Kerekes in seasons 1 and 3. In season 2, and since season 4, she's been voiced by Ilona Molnar (the first voice of Diamond Tiara and Trixie).
- The Croatian HRT dub, due to how it was handled, has several cases of characters receiving more than 1 voice actor during the course of the series:
- Zecora, Rainbow Dash and Rarity all had their own voice actor, but during season 2 Twilight's VA, Katarina Perica Kirin, replaced all of them (Zecora at the beginning of the season, and the other two after "Baby Cakes"). Rarity was also voiced by Andrea Baković, the VA for Pinkie Pie and others, in "Look Before You Sleep".
- Spike was voiced by Jadran Grubišić until the second half of season 2, wherein he got a new male voice actor.
- Diamond Tiara had the same VA as Rainbow Dash, but by the end of season 2 (in "Ponyville Confidential") her VA was also changed to Katarina.
- Scootaloo, who normally shares her voice actor with Twilight Sparkle, was voiced by Spike's former voice actor in "Call of the Cutie".
- In "Bridle Gossip", one of Twilight's lines was voiced by Jadran instead of Katarina.
- During season 1 Sweetie Belle is voiced by Matilda Sorić in "Stare Master", but in all other episodes she's voiced by Andrea instead. In season 2 she gets a different voice actor altogether.
- The songs take it to an extreme; almost all of the songs that involve female characters are sung by a single person - Andrea Baković to be exact - regardless of which or how many characters are singing at once, in many instances even leading to a combined case of Singing Voice Dissonance and Acting for Two. The only exceptions are songs that make heavy use of audio excerpts from the Serbian Mini dub (and those are few and tied to the first season), "Find a Pet" (where Fluttershy's VA and Andrea sing together), "The Flim Flam Brothers" (most of which is sung by male characters, anyway), "B.B.B.F.F." and "Love Is In Bloom" (these last two being sung by Twilight's VA instead).
- Twilight Velvet and Night Light were voiced by Tara Strong and Andrew Francis respectively in their first speaking appearance. When they reappeared again the following season, they were now voiced by Patricia Drake and Charles Demers respectively.
- Pretty much any background pony with a speaking role will have a different voice each time. Some examples:
- Rose/Roseluck has had three or four different voices. Compare this to this to this to this.
- Twinkleshine has had up to four confirmed voices. When she first speaks in the first episode, three actresses (Cathy Weseluck, Nicole Oliver, and Tabitha St. Germain) did her voice because of a mistake by an animator. (Three ponies were present in the scene, for the three characters in the script, but only Twinkleshine's mouth was animated to the words. She gains the Voice of the Legion.) When Twinkleshine speaks again in "A Canterlot Wedding - Part 1", she's voiced by Andrea Libman. In "Amending Fences", she's back to Tabitha St. Germain.
- The twin pegasi Flitter and Cloudchaser were initially both voiced by Cathy Weseluck, but the latter later switched to Ashleigh Ball.
- For her first few speaking appearances as a background pony, Minuette was voiced by the aforementioned Cathy Weseluck, but for her Ascended Extra role in "Amending Fences", her voice was changed to that of series newcomer Rebecca Husain.
- Rose/Roseluck has had three or four different voices. Compare this
- As of "A Hearth's Warming Tail", Princess Luna has a new singing voice courtesy of Aloma Steele, replacing Kazumi Evans.
- The Denser and Wackier spinoff My Little Pony: Pony Life retained most of the voices for the main characters, but Spike's role was taken over by Tabitha St. Germain, while Peter New replaced John de Lancie as Discord.
- The Japanese dub has three different voice casts. The show made its Japanese debut in 2013 on TV Tokyo, however the dub originally ended after two seasons. In 2019, Dlife began airing the series, and restarted production on the dub with a new voice cast. They aired seasons 3 and 4 before the channel shut down in March 2020. In December 2021, season 5 onwards began airing on the Disney Channel (which had previously aired re-runs of the previously-dubbed episodes for a time in September 2018), with the voice cast replaced once again, this time switching to a cast of Japanese actors based in South Korea.
