** Penny--the chubette friend from ''WesternAnimation/ThePebblesAndBammBammShow'', Bubba [=McCoy's=] wife on ''WesternAnimation/WheresHuddles'', and the Chief's secretary on [[WesternAnimation/TwoStupidDogs Super Secret Secret Squirrel]]. Penelope Pitstop may also count, as Peter Perfect and Pvt. Meekley from ''Wacky Races'' call her Penny.
** ''WesternAnimation/TheHuckleberryHoundShow'' had permutations of the Dalton Brothers in a couple of episodes--they would be pared down to three (Dirty, Dastardly and Dinky) for ''Laff-a-Lympics''.
** The face is the same: The Gruesomes on season 6 of ''WesternAnimation/TheFlintstones'' were retooled as the Creeplys for ''WesternAnimation/LaffALympics''.
** Dinky Dalton (''Huckleberry Hound'', ''Laff-a-Lympics'') and Dinky Dog (''The All-New Popeye Hour'')
** Two Ant Hill Mobs: A gang of insect bikers in the Atom Ant cartoon "Wild, Wild Ants", and the mobsters from ''Wacky Races'' and ''The Perils of Penelope Pitstop''.

** Alan--the stud puppy from ''WesternAnimation/JosieAndThePussycats'' and the groovy shades-wearing GadgeteerGenius of the Chan Clan.
** Scooter--the youngest of the Chan Clan, the leader of the Space Kidettes, the penguin on ''The Skatebirds'', and one of the [[WesternAnimation/ChallengeOfTheGoBots GoBots]][[note]]He's a "Guardian", who are the good guys, as opposed to the "Renegades" who are the bad guys.[[/note]].
** Henry--the janitor on ''WesternAnimation/TheJetsons,'' Corry's pal on ''WesternAnimation/{{Jeannie}},'' and the eldest of the Chan Clan.
** Klunk--the assistant in the ''WesternAnimation/MagillaGorilla'' short "Mad Scientist" and the imperfect aircraft inventor of ''WesternAnimation/DastardlyAndMuttleyInTheirFlyingMachines''.
** Curly--Neal of ''WesternAnimation/TheHarlemGlobetrotters'' and Howard of ''WesternAnimation/TheRobonicStooges'', although it is most likely a case of both figures being actual people to start with.
** Two Bettys frequented the same show in the 1979/80 season on NBC's ''WesternAnimation/FredAndBarneyMeetTheThing'': Barney Rubble's wife, and Benji Grimm's friend in the ''Thing'' segments (based on the ''Fantastic Four'' character).
** Chopper--the dog who protects WesternAnimation/YakkyDoodle, the alligator that helps [[WesternAnimation/TheRuffAndReddyShow Ruff and Reddy]] in the "Dizzy Deputies" story arc, and the main villain of ''WesternAnimation/WheelieAndTheChopperBunch''
** Episode Name's the Same: "Don't Fool With a Phantom" was the title of a ''WesternAnimation/ScoobyDooWhereAreYou'' episode and an episode title on ''Scooby-Doo'' expy ''WesternAnimation/TheFunkyPhantom''.
** Agent 000--the code name of WesternAnimation/SecretSquirrel, and the long-suffering boss of the Robonic Stooges.
** Squawky Talky was the name of a parrot in ''WesternAnimation/TheRuffAndReddyShow'' story arc "The Treasure of Skipper Kipper." Twelve years later, "Squawky Talkies" would be the name of an episode of ''WesternAnimation/ThePebblesAndBammBammShow''.
** A pair of chaps named Happy: The photographer in ''Around the World in 79 Days'' (segment of ''WesternAnimation/TheCattanoogaCats'') and Precocia Holiday's big brother on ''WesternAnimation/TheRomanHolidays''. The latter also serves as a StealthPun.
** Huckleberry Hound and their 1968 live action/animated take on Huckleberry Finn.
** Dastardly: [[WesternAnimation/WackyRaces Dick Dastardly]] or [[WesternAnimation/LaffALympics Dastardly Dalton]].
** If homonyms count, there was [[WesternAnimation/TopCat Choo-Choo]] and [[WesternAnimation/TheAmazingChanAndTheChanClan Chu-Chu]].
** Rufus: [[WesternAnimation/WackyRaces Ruffcut]] and [[WesternAnimation/BillAndTedsExcellentAdventures Bill and Ted's mentor]].
** Shag Rugg from ''The Hillbilly Bears'' and Shaggy from ''ScoobyDoo'' could count as the latter is called Shag in informal cases.
** Around 1971, Hanna-Barbera made a pilot for a proposed prime time show called ''Duffy's Dozen,'' about a couple who travel the country in their RV with twelve adopted children. Some of the kids' names would be repurposed for later shows: Alan (''WesternAnimation/TheAmazingChanAndTheChanClan''), Anne (ditto), Corey (''WesternAnimation/{{Jeannie}}'') and Dotty (''WesternAnimation/ClueClub'').
** Dotty (as noted above) is either the trouble-shooter on ''WesternAnimation/ClueClub'' or one of the WesternAnimation/{{Trollkins}} (an obscure H-B show from 1981. Think [[JustForFun/XMeetsY The Smurfs meet The Dukes of Hazzard]]).

[[folder:Transformers]]
* Oddly enough, the ''Franchise/{{Transformers}}'' franchise does this ''within itself''. Being named Prowl, Thrust, Snarl, Inferno, or one of any of the other most common names in the Cybertronian phone book, it doesn't mean you've got anything in common with anyone else with the same name.
** However, they're simply {{reboot}}ed shows' versions of the same character, no different from the [[Series/BattlestarGalactica1978 two]] ''[[Series/BattlestarGalactica2003 Battlestar Galactica]]'' shows each having Starbuck. It's just that [[AdaptationOverdosed there are waaaaay more than two retellings]] of the Transformers' story.
** The toyline, however, is another story. As is the way of these things, fans are a lot more concerned with continuity and such than the makers who just want you to buy it, so when two dissimilar toys are given the same name in the same toyline, or a toy with the name of a character it doesn't resemble comes out, the EpilepticTrees get planted as people try to figure out when the scant lines of bio "take place." Prowl the owl and Prowl the lion both released as WesternAnimation/BeastWars toys? Are they the same guy? Which one, if either, is the same guy as G1 Prowl? There are, in fact, a ''ton'' of toys named Prowl that don't exactly mimic any character named Prowl and are hard to place. Transformers Wiki has a page for each of them, and even some of those pages have a "this is what we think we know; even we can't be sure" section.
*** One weird case is Sky High, which was used for a Pretender one year and then a Micromaster the next, with no relation between the toys.
** In-fiction, there's the Unicron Trilogy, where some ''Anime/TransformersArmada'' Mini-cons have their names re-used for full-sized characters. Most of them don't get their names spoken onscreen, but a few do: The names Dirt Boss, Downshift, Mirage, and Blackout, we'll be hearing from again with characters who clearly cannot be the same ones. Also, the Mini-con helicopter Jolt may or may not be a case: despite both being Mini-con helicopters named Jolt, it's hard to reconcile the backstories of the ''Armada'' and ''[[Anime/TransformersCybertron Cybertron]]'' versions. Also, some ''WesternAnimation/BeastWars'' characters share the names of unrelated [[Franchise/TransformersGeneration1 Generation 1]] characters (while some, like Starscream and Ravage, ''are'' the G1 characters. The show is quite clear on who's who.)
** The movieverse has another version: non-movie material such as comics often movie-ify past characters and use them, and the ''next'' movie comes out and uses the same name with an unrelated character. Sometimes ArcWelding is used (we find out how Arcee becomes one 'bot with three bodies), sometimes not (there's ''no slagging way'' Movie 1 Comic Mudflap and Revenge of the Fallen bad racial stereotype Mudflap are the same guy.)
** Japan's got a different version: Most versions of Optimus Prime are called Convoy. Some get a prefix (Fire Convoy, Grand Convoy, etc.) but then, so do leaders who are not based on Optimus himself (as the ''rank'' Prime is also called Convoy.) Furthermore, what America considers a reboot and what Japan considers a reboot aren't always the same. Therefore, if a character looks like Optimus Prime and is called Convoy or Something Convoy it is ''impossible'' to know if he is intended to be (a) ''the same character as;'' (b) ''a rebooted show's version of; ''or (c) ''a completely different character who happens to be similar to'' any other given Convoy or Something Convoy.
** In a more standard example, the various Autobots named Sideswipe share their name with a character in ''WesternAnimation/TheIncredibleCrashDummies''.
*** And a [[Literature/AWrinkleInTime teenage girl]] shares a (nick)name with a Decepticon Leader.
** It's a running joke in ''ComicBook/TheTransformersMoreThanMeetsTheEye'' that the Transformers have run out of names; one guy changed his name ''from'' Prowl ''to'' Dent.
** Hasbro didn't know that they took the name Victorion from Brave Saga 2.
