*** ''Justice League'' features John Stewart, the Green Lantern, and J'onn J'onzz, the Martian Manhunter. Flash sometimes refers to them as "The Two Johns." In addition, UsefulNotes/ClosedCaptioning for the episodes will sometimes get the names mixed up. Even so, "J'onn" is usually pronounced more like the French "Jean" while Stewart is often referred to as "Lantern" or "G.L.", to mitigate this. Once the show enters the ''Unlimited'' era, ComicBook/{{Steel}} (John Henry Irons) and ComicBook/RedTornado (John Smith) also join the cast, though they're usually referred to by their superhero names.

** There is a Jessica in "How Does Sound Sound?" and a Jessie in "Where Does Time Fly?.

** Lance can refer to both the name of Loud kids paternal uncle and a recurring background character who's a classmate of Lincoln.

*** The very first episode, "On Leather Wings", had both Detective Harvey Bullock and District Attorney Harvey Dent (before the latter's FaceHeelTurn). The latter even addressed the former by name (which sounded a little strange). The former also had a BigBrotherInstinct toward the latter in the episode "Pretty Poison", when he threateningly interrogated an entire restaurant staff after the latter was almost fatally poisoned there. It's largely downplayed from then on there, as Harvey Dent tends to be referred to as Two-Face after his FaceHeelTurn and Harvey Bullock tends to just be referred to as Bullock since most people can't stand him enough to be on a first-name basis with him.

** Three characters named '''Ralph''': Ralph Phillips, a daydreaming little boy, Ralph Crumden, a mouse avatar of Jackie Gleason's character from ''Series/TheHoneymooners'', and Ralph Wolf, a Wile E. Coyote lookalike in [[WesternAnimation/RalphWolfAndSamSheepdog Chuck Jones' sheepdog-wolf series]].
** Three '''Sams''' as well: Ralph Wolf's sheepdog costar, the iconic cowboy WesternAnimation/YosemiteSam, and Sam Cat, a red-furred who was paired up with Sylvester.

** And two '''Egghead'''s. The Elmer Fudd prototype and Miss Prissy's prodigy son that was more than a match for Foghorn Leghorn, later renamed "Eggbert" in the comics.

** There are three Toms: [[TallDarkAndSnarky Tom Sloane]], who dated [[CoolLoser Jane]] and later [[TheSnarkKnight Daria]], as well as [[HenpeckedHusband Tom Griffin]] ([[AlphaBitch Sandi's]] father) and Tommy Sherman (the dead JerkJock).

* ''WesternAnimation/UltimateSpiderMan2012'': Franchise/SpiderMan a.k.a. Peter Parker and The Trapster a.k.a. [[EmbarrassingNickname Paste-Pot Pete]] or Peter Petruski. They got around it by never having The Trapster called by any of his other names.

** ''The Railway Series'' had a bus named Bertie, and a small railway engine named Bert. The show then adds Bert the diesel.
** The TV series had a bus named Bertie, a diesel named Bert, and a Narrow Gauge engine named Bertrum.

** There's also Hank and his baby brother, Good Hank. His dad seems to have been sending him a message there.

** In the episode "Genie Meanie Minie Mo," Timmy's wish for [[RichBitch Trixie Tang]] to fall in love with him backfires when she ends up giving kisses to everyone in the country whose name is Timmy Turner, with him the very last one on the list.

* ''WesternAnimation/TheLoudHouse'' manages to avoid this with the titular family even though they have a ThemeNaming where most of the cast has a four-letter name that starts with L, however Lana and Lola share much more similar names than the others (Lisa, Lynn, Lucy, Lori, etc.). On the other hand, the show does still have examples in regards to side characters:

* ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' has Jimmy and one of his clones gone rogue, Evil Jimmy.

** There are two characters named André: André Bourgeois, the mayor, and André Glacier, the ice cream man.

** In "Itchy and Scratchy Land", after Bart fails to find license plates with his name but finds one with the name "Bort", a child named Bort asks for his mother to buy it, only for a man to think the mother was referring to him when she says his name.

** The most noticeable instance, however, is a character from ''The Ridonculous Race'' and a contestant from the 2023 season both being given the exact same name: Emma.

** There's Velma's rival-turned-friend ([[LesYay and lover?]]) [[TheSixthRanger Marcie "Hot Dog Water" Fleach]] from ''WesternAnimation/ScoobyDooMysteryIncorporated'', Velma's cousin Marcy from ''WesternAnimation/WhatsNewScoobyDoo'named Marcy from one of the video games.

* ''WesternAnimation/FetchWithRuffRuffman'' had two contestants named "Brian" (Brian [=McGoff=] from season 1 and Brian Conroy from season 4) and two contestants named “Jay” (champion Jay Brosnan from season 3 and Jay Ricco from season 5). There were 2 contestants named “Marc” in season 5 (Champion Marc Frongillo[[note]][[OnlyKnownByTheirNickname referred to as Marco]][[/note]] and Marc Prophet) and in season 3 had Samuel "Sam" Blumfield and Samanta "Sammy" Boucher.

** There's Velma's rival-turned-friend ([[LesYay and lover?]]) [[TheSixthRanger Marcie "Hot Dog Water" Fleach]] from ''WesternAnimation/ScoobyDooMysteryIncorporated'', Velma's cousin Marcy from ''WesternAnimation/WhatsNewScoobyDoo'', and Marcy from one of the video games.

* The SpinOff, ''WesternAnimation/TotalDramaPresentsTheRidonculousRace'' does this a lot with names from the old series. There's [[SurferDude Brody]] (similar to [[{{Geek}} Beth]]'s boyfriend [[NotSoImaginaryFriend Brady]]), [[ComplexityAddiction Ellody]] (similar to [[PrincessPhase Ella]]), [[BornUnlucky Mickey]] (just a variant of Mike), and [[TheHost Don]] (pronounced the exact same as [[CuteWitch Dawn]]).
