 * Nmokas: Nameless Mother of Katara and Sokka. Her name is revealed to be Kya late into the final season.

 * The Dangerous Ladies: The other name for Azula, Mai, and Ty Lee. This was probably coined in-show, in "The Chase".


 * The apparent similarities between Azula, Mai and Ty Lee with Haruhi, Yuki and Mikuru respectively has led to the coining of the term Hare Hare Ozai.

 * Maikout: Mai's and Zuko's kiss, drawing on their Portmanteau Couple Name.

Chip 'n Dale Rescue Rangers

 * Various fanfictions give Chip the last name "Maplewood" and Dale the last name "Oakmont". In fact, this is accepted as Fanon.
 * Some fans go as far as declaring "Chip" the nickname form of "Charles", which would mean that he'd share a first name with Monterey Jack's father.
 * Tammy from "Adventures In Squirrelsitting" is often given the surname "Chestnut". Her unnamed mom has been named June in a handful of fanfics as well.
 * However, there are even more names for Tammy's mom to be found in fanfics than last names for the family.
 * "The Rangerillion" gave new names matching its Tolkienesque High Fantasy style to staff members, canonical characters, original characters, fans, and even some classic Disney characters. Due to the impact this story had on the fandom (a Real Life Crowning Moment of Awesome similar to the release of Of Mice and Mayhem, only that it took several months), some fans occasionally use these names in regular conversation, sometimes not even shying away from addressing people, fans in particular, but also staff members, by these names. Examples:
 * Tad Stones: Thaddeus of the Stones.
 * Mickey Mouse: King Mickey.
 * Fat Cat: Feline the Gluttonous.

Justice League/Justice League Unlimited

 * The Legion of Doom: The second Secret Society in Justice League Unlimited, based on their deliberate similarity (including the design of their secret headquarters) to the classic enemies of the Superfriends. One editor has heard that internal documents actually refer to the Society as the Legion of Doom, but can't put their finger on any references.
 * They flat-out mention it in the DVD commentaries for the final season that they essentially referred to the group as the Legion of Doom amongst themselves, but were asked by DC higher-ups to not use it in the show. Hence why the group isn't actually referred to at all by name in the show (apart from Luthor's dismissive comment about it being another version of the Secret Society, which Grodd waves off).
 * It's on the DVD box!
 * Brainthor: The entity formed by in the second season finale of Justice League Unlimited. (Other favorites include "Lexiac" and "Luthoriac", some even differentiating between the two stages of the event.)

 * The Girl In Blue: Another Recurring Extra at Middleton High School who caught the eye of fans. Several names have been suggested, like "Linda," "Violet," and, inexplicably, "Soup.". Some promotional material names her "Linda" and one episode gives her surname as Platt (or it might be the guy in front of her).

 * Derpy Hooves: A grey-furred pegasus who appeared as a background character in the first episode wearing a dopey, cross-eyed expression on her face, and has gone on to make appearances in several other episodes, usually with Fish Eyes. In the second season she's a recurring background character in the vein of Where's Waldo, generally seen in every episode. Very popular with the fans. Also known as Ditzy Doo, which is a canonical name for an unidentified, scatterbrained pegasus who went north to retrieve the southern birds (and west the previous year) and partially endorsed by Lauren Faust.
 * In a rare instance of the fan nickname becoming canon, "Derpy" went from a fan nickname, to being used in the promotion of the December 2011 holiday special, to being used on an episode of the show in January 2012 (in an episode that also gave Derpy her first speaking appearance).
 * Dr. Whoof/Dr. Whooves: An earth pony with an hourglass-shaped cutie mark and an uncanny resemblance to David Tennant who appears in a few episodes as a background character. Fans don't seem to have decided on a name.
 * Colgate: A background pony who has a blue mane with a white stripe running through it.
 * She is occasionally also referred to as Romana due to sharing the same cutie mark as Dr. Whoof.
 * She was seen dressed up as a dentist in the Halloween Episode. Coincidence or Ascended Meme?
 * Pony Gaga: Rarity in her Pimped-Out Dress and Uncanny Valley Makeup from "Sonic Rainboom". The nickname has also been used for Photo Finish from "Green Isn't Your Color".
 * Steven Magnet: the camp sea serpent from the second episode, "Elements of Harmony". The nickname comes from a caption generated by YouTube's closed-caption auto-generator.

 * DisQord: Discord, Big Bad of the season 2 premiere, quickly attracted this nickname after fans found out he was voiced by John de Lancie, who played Q (who was also a reality-warper with a twisted sense of humor) on Star Trek: The Next Generation.
 * Tom Dan: A rock that Rarity befriends in the season 2 premiere . Canon name "Tom", but called "Dan" due to Youtube Caption's.
 * Screwball: A wall-eyed (possibly due to Discord though) purple pony who first appeared in the season 2 premiere, with a baseball and screw as her Cutie Mark.
 * Dream Beauty Celestia: The large talking Celestia toy, referred to as thus because it is the same size as ponies from the G1 Dream Beauties subline.
 * Also sometimes known as "Hasbrolestia".
 * Doctor Fantastic: Rarity's dad in "Sisterhooves Social", thanks again to Youtube's automatic captions. His resemblance to Tom Selleck as the title character of Magnum, P.I. also lead to fans calling him "Magnum".
 * Twilight Snapple/Psycho: Twilight Sparkle during "Lesson Zero", when she went insane over her obsession with friendship lessons.
 * Roid Rage: The tiny-winged, comically-muscular white pegasus stallion from "Hurricane Fluttershy" who keeps yelling "YEAH!". He's also known as "Big McLargehooves" and "Snowflake".

 * Dr. Finkly: Dr. Finklestein, by his fans.

 * Mrs. Brisby's unstated first name is "Elizabeth" in Fanon. This is a tribute to her voice actress, who committed suicide not long after.

 * By a hair, Daddy Todd, but no one says it anymore. During the brief period where Todd and Kristin agreed to take care of LL together. It didn't last long.
 * It should be noted that a lot of nicknames came around AFTER the shows cancellation, and thus a lot of this isn't canon happenings, just things that happened in the "official" Sym-Bionic Titan RP. Yes, that's right. There's an official one.

Teamo Supremo

 * Bruno: The Birthday Bandit's large male Party Favor.

Teen Titans

Characters


 * Megs: Megatron, from any given Transformers series. Was once applied canonically to Beast Wars Megatron, but has been used before and since in fandom circles.

 * The Stooges: Slapper, Dark Scream, and Gas Skunk, from Transformers: Robots in Disguise. The three of them are comic relief villains who are always seen together.
 * In Armada, Thrust was called "Squidhead".
