The Animaniacs fan series Zany to the Max introduces Pakko and Jot. Pakko, like his cousin Wakko, likes to eat a lot, which makes sense since his name is somewhat of a Shout-Out to PacMan. Jot is the fastest of the Warners, and she's known for being somewhere in a jot.
The Siamese Quadruplets, the collective name for Kat the Cat and her three sisters (whose names are Kate, Katie, and Jessica). They're Siamese cats, and their Backstory reveals they used to be conjoined before their first appearance, making them former conjoined quadruplets.
In The Bridge, although no fan creations make up the main cast, the Fan Nick Name of Xenilla, an amalgam Xeno (alien) and Godzilla, is used in place of the official name Spacegodzilla for an extraterrestrial clone of the scaly goliath.
Cheney's middle name, Difronte, is Italian for opposite, since his two jobs virtually contrast the other in function and purpose. The actual Italian term for opposite is 'di fronte', but the two separate words was combined into one to create the name.
Kanin's middle name, Leporidae, comes from the Classification Family for Rabbits. She's a Feol Viera.
And "kanin" is Swedish (among others) for "rabbit".
Crockett, his name is derived from the crook of a shepherd's cane. His ability to control and herd Baknamy are reminiscent to that of a shepherd controlling a flock of sheep.
Cama Leonte. Camaleonte is Italian for chameleon. His success at blending into the Archbishop guard reflects the animal's ability to blend into its surroundings.
Luso Clemens. Clemens means peaceful and his dad told him that Luso is soul with the letters switched around, meaning his name means peaceful soul. The soul part is significant as his dad named him such because he knew that Luso would grow up to be a person who could share his soul with everyone (possibly not literally), connecting with them, and giving his mere presence a positive effect on his clanmates.
In the Elemental Chess Trilogy, the Big Bad is called Acheron, which is the name of a river in Greece. In ancient Greek mythology, the Acheron was one of the five rivers of Hades and was known as "the river of pain." Also, in the third installment, meaningful names are given to Roy and Riza's twins; since in the series' Chess Motif Roy and Riza are the king and queen, their son is called Brendan, which means "prince," and their daughter is Riana, which means "little queen".
In The Ollivander Children, the Ollivander children were deliberately given significant middle names by their father - Clemence, Fortitude, and Blithe - to reflect his gratitude at their safe births. Appropriately, his son Linus Fortitude is The Stoic, but less so, Calliope Blithe, has a Sugar and Ice Personality through and through.
The surname Michikyuu is commonly written with two kanji. Among others meanings, the first kanji can be translated as journey or teachings and the second one as gift or grant. Like this, the word "Michikyuu" can be read as "the gift of journey" or "to grant teachings". She's a slider and her arrival enabled Kyon to learn martial arts at a ridiculous pace.
Kyon's own name, as "semi-revealed"note Nothing out and out says that the name in question is Kyon's own real name, and the author himself keeps humorously responding to inquiries about the issue with "Further information is not available at this time." However, several subtle hints lend significant support to that belief. at the beginning of some chapters' epigraphs and through some in-story hints, is equally meaningful. Taira no Tadamichi (aka Usui Sadamitsu) is the real name of a samurai involved in a Japanese legend, who was from one of the four families that held the power behind the Japanese throne from the 9th to 12th centuries. The other three families were Fujiwara (the other time traveler), Tachibana (the other esper), and Minamoto (which was historically based in the same geographic region as Nishinomiya). As for the meanings of the names, Tadamichi can mean straightaway/honest/frank/fix/repair | person/alternative/direction and Kyousuke can mean great | law/rule/ceremony/code. Think how Kyon has affected Haruhi. It has also been discovered that Kyon is likely descended from Usui Sadamitsu and certainly owns what's left of their sword.
Some Semblance of Meaning is full of it. Vale's name can refer to a "low place" or a lament. Her district partner Kit Littleby's name refers to his smallness. Lavinia Gilden's last name implies that, while she may be "golden" and Capitol-ized on the outside, she is still a citizen of District Twelve on the inside. Many tributes' names refer to the district from which they hail, as well.
Many in Under The Northern Lights. "Saga" can mean both "seer" and "fairy tale": Saga has flights of fancy and is an actual seer. Lord Eminence is a gray unicorn: an "éminence grise", gray eminence, is someone having political power behind the scenes or informally, which is what Lord Eminence tries to achieve.
In Act I of Legends of Equestria, Princess Celestia's birth name, Celeste, obviously shares a root with the name she would eventually choose for herself.
This is, however, inverted with her sister Claire, whose name has absolutely nothing to do with the moon.
The name of Discord's capital city in Equestria, Eridian, references Eris, the Greek goddess of discord.
The names of all the Ancient Masters in Act I are referential to their chosen elements: Terraria = Earth, Altas = Air, Seraph = Fire, Aquos = Water.
In "Fluttershy Is Free," the name "Fluttershy" was given to her by her mother because her mother thought she was sired by a flutter-pony. Her mother may even have been right — for certain values of "flutter-pony."
Invoked and Lampshaded in Black Queen, Red King: The changelings choose their own names, sometimes in their gibberish native language. When Tarukenote Protector comments on this, Klikanote Daughter replies, "We all name ourselves; Protector, Slaughterhouse, Daughter, Stalker – of course it’s fitting."
In Weiss Reacts, we have in addition to the protagonists the whole of team MLDY:
Melodia Viridi's name refers to her Semblance and favoured color green, Lukas' name is derived from Loki and Yukari's last name means Wind God, referring to her Semblance.
As for their weapons, Twin Heavens is derived from the fighting style Miyamoto Musashi, Yukari's inspiration, used, Nari and Vali were Loki's sons, and Mors Certa means 'certain death'- the spear itself is based of Gae Bulg and Fragarach.
Also, Ludwig Amadeus is the Music professor, Andreas' name is based off the root for 'man', Norn's name is meant to recall Elda and Freya and so on.
In Smash Generation, there is an original character named Shiroi Karasu, who is the only person in the entire Karasu clan with white hair and a white crow. In contrast to her name, she has a twin sister who follows tradition of having black hair and a black crow... named Kuroi.
All the characters from the story 'The New Millennium' have been stated to have been named based on their qualities. Bennu means 'Reborn One' in Arabic, indicating that she was a reincarnation of Yugi, and Celeste means 'Heavenly' possibly referencing her transformation into an alienesque creature.(The exceptions are Tai and Ran, who haven't been given definitions yet.)
Billy The Kid in "Sin City Kids", due to his signature goatee.
