American Dad! took the entire family archetype from Family Guy and transfered it near Washington D.C., as well as replaced the dog and baby with a goldfish and alien. However, the characters do distance themselves from the Family Guy cast more than the Cleveland Show. Stan, is less of Cloud Cuckoo Lander than Peter, and more of a chronic Ax-Crazy. Francine is The Ditz, rather than the Only Sane Woman, and the Butt Monkey staff is handed to Klaus rather than Hayley.
The Cleveland Show borrowed most of its characters from other Seth MacFarlane shows and then turned them black (Rallo = Black Stewie, Cleveland Jr. = Black Chris, and Roberta = Black Hayley to name a few). Similarly Cleveland himself begun as a more soft spoken Extreme Doormat, but was actually evolved into the same abrasive Bumbling Dad archetype as Peter and Stan when he gained his own spin off. Seth Macfarlane's team seem to follow the same character dynamic to a tee for each show. And of course, while the basic character roles may be recycled, their actual personalities are wildly different. Most notably, Rallo is overprotective of his mother instead of insanely matricidal. Nor is he a stereotypical homosexual. Peter and Brian themselves are based on the main characters characters of this old short Seth made for The What A Cartoon! Show.
Auntie Momma is an OBVIOUS expy of Tyler Perry's Medea.
Ellen Yin and Ethan Bennett from The Batman are more or less counterparts of Renee Montoya and Crispus Allen. Which is a bit funny because Renee Montoya originated in B:TAS and became a Canon Immigrant.
Detective Ellen Yin also heavily resembles Elisa Maza transposed into the Batman universe. She even wears the same outfit. Interestingly, Greg Weisman also wrote a handful of episodes for the series.
Also, Ethan Bennett is Harvey Dent. From the long friendship with Bruce right down to calling Batman "Bats," a la Harvey from The Long Halloween.
A interesting case of the Bat embargo. During the "interviews" segments they reveal due to Teen Titans they were restricted in who they could use.
Batman: The Brave and the Bold's Morgan Le Fay almost identical to Disney's Maleficent, both being powerful evil witches obsessed with gaining power who magically transform into dragons to fight the heroes, even both dying from being stabbed in the stomach by a magical sword while in dragon form.
At least visually, the show's version of Katana was influenced by Gogo Yubari from Kill Bill.
Kru'll the Eternal is an Expy of both Vandal Savage and the Shazam foe King Kull, , with a hint of Darkseid's son Kalibak.
Fun Haus substitutes for Toyman and/or Prankster with some Joker tendencies, but no one's really sure.
Slug seems to be a stand-in for Sleez from the New Gods and/or Tobias Whale, in terms of looks and personality.
Scream Queen is a redesigned Silver Banshee.
The Music Meister strongly resembles a modernized version of The Fiddler, using singing instead of violin-playing for his mind control.
He much more closely resembles Fiddler stand-in Music Master from the Justice Guild episodes of Justice League, down to the wild hair and gapped teeth.
Equinox shares a similar backstory and obsession with balance to Silver Age Libra.
The Faceless Hunter to the Silver Surfer, with a twist. Like the Surfer, he is the herald of an oncoming scourge of entire worlds, a deal he made with said scourge - Starro in this case - over the fate of his own planet. The twist being he's everything the Surfer isn't. Norrin Radd became the Surfer in exchange for Galactus sparing his world. In this case, though, we find out in the final battle that when Starro found a faceless race that his facehugging mini-Starros could not control, he was just going to leave, but the man who would become the Faceless Hunter said that he would find other worlds for Starro to enslave in exchange for Starro destroying his world. He proves to be an Omnicidal Maniac and eclipses Starro as the final enemy of the season finale.
Ted Kord's heroic death has much more in common with that of Captain America's sidekick Bucky than his actual death in the comics.
Ben's alternate forms in Ben 10: Alien Force seem to be Expys of his forms from the original series, albeit with different mixes of Combo Platter Powers: Swampfire is a mix of Heatblast and Wildvine, Chromastone is the new Diamondhead, Big Chill is Ghostfreak, Arcticguana, and Stinkfly, etc.
Professor Paradox is a blatant Expy of the The Doctor. University professors are normally Doctorate holders and a paradox is a type of contradicting statement(s).
They even went so far as to make his real name a mystery.
Will Harangue from Ultimate Alien is a blatant J Jonah Jameson Expy, with some features resembling news pundits like Glenn Beck, Keith Olbermann, and Bill O'Reily thrown in for realism.
After being unable to make any sense of Kevin's change from The Sociopath to wisecracking Anti-Hero, the team behind Alien Force and Ultimate Alien have taken his prior characterization and powers, made it grown-up and mature, and have named it "Aggregor", who is truly a foe to beware.
Some aliens are even expies of past aliens. Fasttrack is XLR 8 with a Wolverine helmet, and Eatle is Upchuck as a bug. No changes at all beyond the look. Astrodactyl is also a Jetray ripoff (even has a reddish body and green Frickin' Laser Beams) but he has one power Jetray doesn't in the form of his energy whips.
Charmcaster is an expy of Scarlet Witch, as both are evil sorceresses who eventually become good. Even her Alien Force/Ultimate Alien suit slightly resembles the Marvel character.
Beware the Batman was intended to use some of Batman's lesser known enemies in place of his regular Rogues Gallery. However, this means that some of those B and C-list villains have had their characters tweaked to fit into the roles of more well-known adversaries. For instance; Anarky is The Joker, Magpie is Catwoman, Humpty Dumpty is The Riddler and Tobias Whale is a more serious Penguin. Arguably, Professor Pyg, as an ecoterrorist, could be considered a very loose Poison Ivy analogue. Anarky is especially egregious, as in the comics he is a slightly preachy teenage Anti-Hero and champion of the downtrodden who was designed to subvert Anarchy Is Chaos, whereas the cartoon version is a giggling maniac who creates chaos for chaos' sake.
Bimble's Bucket takes a lot of similar character archetypes from Mike Jupp's previous show The Dreamstone. While Bimble is basically a Rufus duplicate, Dolly Clackhanger and her docile minions very much resemble Sgt Blob and his cadets, with Mudge replacing Urpgor as their pompous rival for the approval of despot Big Bad Queen Kak, who replaces Zordrak. In some cases even the character designs are only slightly tweaked from those of the initial show (the hero species are anthropomorphic rabbit-like civilians while the villains are big nosed humanoids).
A rare live action-to-animation example is Calvin and the Colonel (ABC 1961-62), an expy of Amos n Andy. What happened was that by the late fifties Amos n Andy was viewed as racist so the producers responded by taking the same show, turn it into a cartoon, and replace the characters with Talking Animals. An early attempt at doing prime-time cartoons, the show bombed in ratings and was taken off the air the following season.
Lizbeth Zaragrosa and Kitty Ko are eerily similar. Both are young Asian girls with strong crushes on young idiot superheroes who are oblivious/disinterested in their advances with shows that are broadcast on YTV.
Dash Baxter serves as an expy for Flash Thompson: they're both Jerk Jocks who bully their protagonist while at the same time being the biggest fan of his superhero alter ego.
Jack Fenton is an Expy of Mr. Fantastic. Both are scientists and inventors who have made a portal to another dimension, have white streaks in their hair, and an arch-enemy who has been holding a grudge on them for years.
Star is Veronica Star from The Fairly OddParents, all grown up. Same name? Check. Blonde? Check. Satellite to a non-white Rich Bitch? Check. A cheerleader? Check. The only major difference is that she is voiced by Tara Strong, not Grey Delisle.
Tucker is an expy of Steve Urkel from Family Matters, only without the annoying nasal voice.
The Guys In White are a pretty obvious expy/parody of the Men In Black comic/film series, replacing aliens with ghosts.
Hobson from "Livin' Large" has the same job, appearance, personality, voice, and name as John Gielgud's character from Arthur.
The Dating Guy was (allegedly) created from Teletoon execs using the original pitch for a Least I Could Do animated series. As such, you can see the original characterization of the LICD characters in The Dating Guy, but most of them were shifted to adopt things suggested to the LICD creators in the original pitch.
Jiminy Cricket (Pinocchio) and Timothy the Mouse (Dumbo) fulfill the same kind of roles in their respective stories. They are both tiny, but feisty animals who help out a naïve childish character and act as their conscience and/or moral support.
Alice (Alice in Wonderland) and Wendy (Peter Pan) have the same kind of personality. They are both straight characters and polite and mature for their age young girls who don't take no nonsense. They even both have a scene where they manage to make everybody in their vicinity cry out of empathy.
The protagonists' horses in Sleeping Beauty, Hercules, Mulan and Rapunzel all look and act almost exactly the same. They are mute, so they communicate through facial expressions. They are also impulsive and often disapprove of their masters' kindness towards people they dislike.
Wilbur and Orville from The Rescuers and The Rescuers Down Under are basically the same albatross, down to the design and character, though this was a conscious decision on behalf of the animators. By the time the sequel was made the original voice of the bird in the first film had died and out of respect for the actor they created the same kind of character, but presented him as his brother.
Though even Wilbur & Orville have much in common with Launchpad Mcquack, also a feather brained bird pilot who crash lands more than he flies.
Baloo (The Jungle Book) and Little John (Robin Hood) are very obvious expies of each other. Apart from being two big dumb and strong bears various scenes in Robin Hood have been rotoscoped from similar scenes in Jungle Book. Kaa and Sir Hiss too, by the way, even sharing a similar hypnotizing snake scene.
Obviously, everyone from Drawn Together is an Expy from their respective animation (or other) genre:
Princess Clara is, personality-wise, a generic Disney Princess but in appearance is an expy of Ariel.
Captain Hero is Superman. He's a super-powered alien from a planet that blew up, sending him to Earth. Unlike Superman, he feels no sort of responsibility to do the right thing and is an aggressive alcoholic.
Toot is an (older and washed up) expy of Betty Boop.
Xandir's most notable similarity is Link, but only vaguely. It's a bit of a stretch to call him an expy when the only similarity is blonde hair, pointed ears, a sword and a neverending quest to save his girlfriend boyfriend. He's really meant more to symbolize effeminate video game heroes in general.
He was even referred to as "Poorly conceived Spongebob parody" in one episode.
There's some similarity in attitude to Stimpy as well.
Ling-Ling is a direct expy of Pikachu, right down to having been trained by a boy who looks a lot like Ash Ketchum. We even see Ling-Ling evolve at one point, though the process seems to be very different here.
Spanky resembles various characters from Internet comics and flash animations. But mostly he resembles the Napster mascot cat, changed to a pig, right down to the extra-bold lines he's drawn with. His gimmick, "an Internet download" refers to illegal downloads popularized by Napster.
And there's another nod to past continuity in that Porko physically resembles Porky's comic book nephew Cicero, with his sailor suit and cap.
At least three of the characters in Extreme Ghostbusters are expies of the original Ghostbusters; Eduardo Rivera = Peter Venkman, Garrett Miller = Ray Stantz (at one point, in frustration, Egon accidentally calls Garrett "Ray") and Roland Jackson = Winston Zeddemore. The process of elimination would suggest that Kylie Griffin = Egon Spengler, but Egon is actually IN that cartoon in the background.
Family Guy had this in one episode with Penelope, a one year old girl who is basically Stewie if he was still overly violent and kept trying to take over the world.
Mac, the protagonist of Foster's Home for Imaginary Friends, is based on an exact clone of a one-time Powerpuff Girls character, Mike (note the names). In that episode, Mike came in as a new student with an imaginary friend (take note) and trouble started brewing afterwards. The students blamed him for causing all this, but it was really his imaginary friend doing the mischief. Mac and Mike look exactly the same except Mike has an outline.
And also Mike has shorter hair.
Mom from Futurama is very similar to Mr. Burns from The Simpsons since both are rich, ill-tempered, and emaciated.
Speaking of Gargoyles, there was an epic twist on this trope in the show: Fans hated Preston Vogel for seeming too much like a less-fleshed out version of Owen Burnett, who showed up first. They were both stoic, glasses-wearing assistants to some of the most powerful men on Earth, with the main difference being Vogel's darker hair. Then it turned out that Owen had entirely modeled himself on Vogel, trying to "out-Vogel" him because Owen was secretly Puck the fey all along, making him the real In-Universe expy.
House of Mouse's "King Larry" was an Expy of Louie, created to avoid legal issues when the Louis Prima estate charged Disney of not paying royalties to Prima for TaleSpin and The Jungle Book. Baloo, Louie and Shere Khan may have been reframed in a different scenario and time period, but were still the same characters.
The 90's Iron Man series had a Canon Foreigner villainess named Hypnotia, who was a thinly-veiled Expy of Enchantress from the Thor comics.
Hro Talak is not quite Katar Hol, but his name is an anagram and he was also given a past relationship with Hawkgirl.
Galatea is not exactly Power Girl, but she wears a similar costume, which one scene made identical with the addition of a red "towel" hanging over her shoulder, and shares the background of "not exactly Supergirl, but close."
In the same episode, the screaming minions that the heroes fight in Ithuclu's world are clearly based on Marvel's Mindless Ones.
The Justice Lords from "A Better World" were heavily inspired by The Authority, which the producers had begun to read between seasons one and two, and one idea they had was to see what the world would be like if the League ever tried to emulate their tactics.
When Brainthor summons up robot versions of the Justice Lords to distract the League, he has to create a new one for Flash (since Flash of that universe died before they became the Lords). The costume he gives Flash is identical to the costume of famed Flash Villain Professor Zoom, The Reverse-Flash.
The giant turtle that attacks Japan in "Chaos at the Earth's Core" is an expy of Gamera, as well as being a Mythology Gag to Jimmy Olsen's comic book.
Ace is one to Tamara. Both are young girls with black hair and powerful psychic abilities and were use by shady organization and are also associated with a Batman.
Wade Eiling becomes an Expy of The Hulk by using the Captain Nazi serum. He's more articulate but possibly even more dangerous due to being a Principles Zealot.
Similarly, the Ultimen are expies of the Super Friends original characters, the Wonder Twins, Black Vulcan, Apache Chief and Samurai.
The entire episode was a homage to Super Friends; the Ultimen base on top of the skyscraper looking like the Hall of Justice, Long Shadow's cell ringtone being the old theme, even how they only used Superman, Batman, Aquaman, and Wonder Woman as the hero team in the episode.
Earlier than those two, the Justice Guild was a very thinly-veiled Expy of the Justice Society of America; the villains of the episode were themselves Expies of The Wizard, Icicle, Sportsmaster, and The Fiddler. Their two-part story arc was an adaptation of the first JLA/JSA team-up story set in an Adam West-styleWorld of Ham. This was done mostly because DC wouldn't allow them to use the actual JSA as was planned, thinking that a story presenting the JSA in the goofy (and slightly racist) style that that episode did would shine badly on the recently relaunched JSA comic series. It worked out well for the producers, though, as they were able to use the characters legitimately in JLU later on.
The beginning of the episode had the League fighting a giant robot that looked just like an Evangelion with the serial numbers filed off.
There's also Devil Ray, who is basically Black Manta with a name change. His rivalry with Aquaman is never mentioned (due in part to the rights for the character being held up by the WB's plan for a Smallville style show focusing on him), instead being matched up against Wonder Woman for most of his appearances.
Several characters are fantastic expies of real-life figures:
Hiroshi Sato is an expy of Henry Ford, a famous industrialist best known for mass-production of cars.
Varrick is this universe's Howard Hughes - an eccentric businessman involved in aviation and film with a love of cookies.
President Raiko is similar in appearance to Sun Yat-Sen, China's first president.
Korra's father Tonraq is an expy of Katara and Sokka's father Hakoda. They're both the chief of the Southern Water tribe and father to the primary water-bender of the group, who they don't get to see as often as they'd like due to obligations of their positions. They also both wind up fighting an asymmetrical battle against a much stronger force.
Little Audrey is both a Captain Ersatz and an Expy of Little Lulu, since she was created by the animators at Paramount-Famous, the same studio that animated Lulu. Audrey was created after Paramount lost the rights to Lulu from her creator, Margarie Buell.
Looney Tunes character Ralph Wolf (the one who keeps trying to steal sheep) is indistinguishable from Wile E. Coyote except for his red nose. Both characters were created by Chuck Jones, and are customers of Acme Products. They weren't always indistinguishable, but later animators became lazy with the character design after having done so many more Wile E. cartoons than Sam and Ralph cartoons, dropping most of what little differences there had been.
In one Looney Tunes comic book, Wile and Ralph meet, turning out to be long-lost brothers. They both realize that they both failed to get their respective targets (the Road Runner and the sheep, respectively), so they team up to catch the Road Runner. And fail.
Despite the recycled character design, there is quite a fundamental difference regarding how Wile E. and Ralph are each utilized in their respective shorts - Wile E. is a true blue fanatic, totally and utterly obsessed with catching the Roadrunner, while Ralph is very literally a Punch Clock Villain (indeed, outside of work, he and his professional nemesis, Sam Sheepdog, appear to be the best of friends).
Likewise, Alexander Graham Wolf from Chuck Jones' Raggedy Ann and Andy special The Great Santa Claus Caper is an Expy of the "genius" version of Wile E. Coyote who appeared opposite Bugs Bunny.
Mary Shelley's Frankenhole's "Dr Polidori" is is a double-expy: his name is taken from Lord Byron's personal physician, who was involved in the same dare that had Mary Shelley write Frankenstein, and his performance is based on that of Ernest Thesiger as "Dr Pretorius" in The Bride of Frankenstein. The werewolf that appears in the credits and in a couple of episodes looks like the Lon Chaney Jr "Wolfman". Dr Frankenstein, on the other hand, doesn't seem at all like any performance of "Dr. Frankenstein" I know, and definitely not that of Colin Clive.
The werewolf's name is Stewart Lawrence, a combination of Lawrence Talbot (the Wolf Man) and Jimmy Stewart, who his voice actor is imitating.
The Mighty B!'s Bessie is a version of a character Amy Poehler did for The Upright Citizens Brigade: a hyperactive ten year-old Girl Scout. Saturday Night Live's Kaitlin was a watered down version of the character, making her a spiritual cousin of Bessie. In a way, the freedom of animation makes Bessie a purer version of the character than the original! Amy Poehler, who plays Bessie, is one of the credited creators of the show.
Bogus's enemies, Ratty and Mole, are essentially expies of Elmo and Ferd, respectively, a conniving mouse duo who appeared as One Shot Characters in the Garfield and Friends episode "Trial And Error", although Ratty actually seems to share some facial similarities with those of Socrates.
Also, Bogus's overbearing Aunt Bogunda appears to share some similarities with Mrs. Marcus.
Tommy's mother, Mrs. Anybody, looks a little bit like Jane Jetson.
Jake and Butch, the two burglars who Bogus constantly tangles with, also appear to be direct parodies of that of Harry and Marv.
My Little Pony: Friendship Is Magic was originally intended to be a Continuity Reboot of the very first series. It turned out, however, that the copyrights on most of the original ponies had lapsed, and so Lauren Faust was forced to create similar substitutes of the original mane 6, with the exception of Applejack. Some of them became a Composite Character. Eventually, they evolved into their own distinctive personalities.
Twilight Sparkle: Twilight/Twilight Twinkle
Pinkie Pie: Surprise
Rainbow Dash: Firefly, with g3 Rainbow Dash's colors
It should also be noted that Twilight Sparkle's mother looks like the original Twilight.
Discord, the villain of the Season 2 premiere, was conceived after Lauren Faust had done an Archive Binge of Star Trek and was very much modeled after Q; the plans were originally to get a soundalike of Q's actor John de Lancie but they ended up getting de Lancie himself (turning it into an Actor Allusion as well). He also shares some traits with a villain from one of Faust's previous shows, Him from The Powerpuff Girls (Faust even says that her husband, PPG creator Craig McCracken, contributed to Discord's character design).
The Cutie Mark Crusaders form a Power Trio similar to the Powerpuff Girls themselves.
The Flim-Flam Brothers seem like a 2-in-1 expy of Mr. Lanley from The Simpsons episode "Marge vs. The Monorail", right down to the vaudevillian get-up.
Iron Will the Minotaur, from "Putting Your Hoof Down," is about equal parts Hulk Hogan and Mr. T.
The hero from the movie Mordecai and Rigby watch in "Grave Sights" looks like Ash from Evil Dead.
Kessler and Costello from "Steak Me Amadeus" look almost exactly like Mulder and Scully.
Maia Sterling (the other daughter of Max and Mirya) in Robotech: The Shadow Chronicles, appears to be an expy for Aurora Sterling (the other daughter of Max and Mirya) from the Jack McKinney Robotech novels. So far, Maia hasn't shown any psychic powers.
In the Samurai Jack episode "Jack and the Labyrinth" a character appeared (called "The Thief" in the credits) who was a Composite Character Expy of Daisuke Jigen and Lupin the Third from Lupin III. His suit and hat were white instead of black, and he used a briefcase that doubled as a machine gun rather than a conventional firearm, but the style of his suit and beard were identical to Jigen's. His personality, on the other hand, was based more on Lupin's behavior.
The episode "Jack and the Gangsters" featured expies of the Ant Hill Mob from Wacky Races. The leader of the Ant Hill Mob was himself an Expy of Rico Bandello from the live-action film Little Caesar.
Talon from Spider-Man: The New Animated Series was originally supposed to be Black Cat, but was changed to an original character once the producers snagged the rapper Eve for the part.
Sponge Bob Square Pants has Mermaid Man and Barnacle Boy, a parody of Batman and Robin, respectively, down to the fact that their flashback selves are voiced by Adam West and Burt Ward. They are not Captains Ersatz because they have some attributes of other heroes. Appearance-wise, Mermaid Man and Barnacle Boy resemble Aquaman and Aqualad, respectively.
Spongebob and Squidward have elements of Renand Stimpy to their personalities. Patrick is possibly like Sven then.
Early Cuyler from Squidbillies is pretty much the character of Unknown Hinson, performer persona of his V.A. Stuart Baker, in squid form.
Superjail! has the Warden, who was pitched as a "sadistic Willy Wonka" who owned a jail instead of a chocolate factory. He was initially not even going to have the top hat and tailcoat like Wonka (or even wear purple), but the creators decided to run with the idea after deciding he was enough like the character.
Lord Stingray is meant to parody Cobra Commander, although the network executives (and many fans) mistook him for parodying the Venture Bros.' villain Monarch. The other two villains shown in his debut episode are meant to be parodies of the Baroness and Destro, while the army force sent to capture Stingray ("The Stars N Stripes") reference the GI Joe team.
D.L. Diamond, aside from his L. Ron Hubbard inspiration, was designed as a visual shout-out to David Lee Roth and Klaus Nomi.
And oddly enough Kairo later received his own Expy decades later in Batman Beyond with the character of Kai-Ro, a young Asian boy who was chosen as Earth's new Green Lantern after John Stewart retired.
Solomon, the leader of G3 in Sym-Bionic Titan looks very similar to Alucard, particularly the hat, glasses, uniform and pale complexion.
Interestingly though, Word of God states TaleSpin exclusive character Rebecca Cunningham to be based on Rebecca Howe of Cheers.
Ever since Rosie's debut in the Thomas the Tank Engine series, her and the titular character bear a striking similarity to that of Sonic the Hedgehog and Amy Rose as far as the Pink Girl, Blue Boy trope is concerned. Both male characters are blue and are often annoyed with the clingy respective female characters in pink.
Teen Titans had a few. Sarasim was an Expy of Cyborg's love interest Sarah Simms (possibly with elements of his later girlfriend Sarah Charles thrown in as well), the Puppet King was based off the Puppeteer, Billy Numerous was based off Multiple Man, and Larry was based off Bat-Mite.
There's also a few characters serving as visual Shout Outs to various DC heroes, such as Private H.I.V.E. being based off the Guardian and Val-Yor looking like Captain Atom.
Tiny Toon Adventures is a combination of this trope and Spinoff Babies, as all the main characters are younger Palette Swap versions of the original Looney Tunes, who are actually there in the background as teachers in Acme Looniversity. Probably the Tiny Toon who's the furthest from her Looney Tunes counterpart is Elmyra. (Basically, she's more of an Evil Counterpart than an Expy.) Unlike Elmer, Elmyra LOVES animals, and is female. Ironically, unlike Elmer, animals find Elmyra genuinely frightening.
Pam, Alice, and Crimson from Totally Spies! are Expies of the three Kisugi sisters from Cats Eye, right down to looking exactly like Palette Swapped versions of the girls. The joke is lost on American viewers, but is meant to be a Shout-Out, since Cat's Eye had a very popular French dub in the 80's.
Alex was also the show's Expy of Ai Kisugi way before Crimson showed up. Her name is even taken from Ai's Dub Name.
The Transformers franchise is constantly rebooted, technically making Optimus, Megatron, Starscream, etc. expies of about eight or so identically-named characters. And then, there are other examples:
Beast Wars actually has several Starscream-expies:
Terrorsaur is the cartoon's Starscream, with the obvious, transparent, why-doesn't-Megatron-just-kill-him backstabbery. His success rate is about as good as the original's, although Starscream managed to stay second in command. On the upside, Terrorsaur at least realized that the treachery thing wasn't working and stopped.
Several of Sentinel Prime's design elements (he's energetic, mostly blue, with a very prominent chin) are based on The Tick, with whom he shares a voice actor. This was done on purpose after said actor was cast for the role.
Omega S.P.R.E.E.M. was a homage to Omega Spreem, an obscure toy from the Generation 1 Action Masters line.
Korvac from Ultimate Spider-Man is an expy of Thanos, even though Korvac himself originated in the comics as well. His status as a cosmic tyrant and the leader of the Chitauri both come Thanos, especially the MCU version.
The show's version of Scorpion is a ninja with a grappling hook.Hmmm...
Black Spider, an operative for the League of Shadows, despite being based on a DC character named Black Spider, he's Spider-Man if Spider-Man was evil. He makes wise cracks during battle, he's voiced by Josh Keaton, and he even refers to swinging through the city as 'web slinging.' Of course, "Evil Spider-Man" was pretty much the premise for the original comic character as well.
This show's version of Lex Luthor borrows heavily in terms of both personality and methods from David Xanatos, who was also created by Young Justice showrunner Greg Weisman.
Well, basically Hanna-Barbera has made a career out of exporting characters from wherever! During the Simpsons episode "The Day that Violence Died" Roger Meyers Jr. says that "Animation is built on plagiarism! If it weren't for someone plagiarizing The Honeymooners, we wouldn't have The Flintstones. If someone hadn't ripped off Sergeant Bilko, there'd be no Top Cat. Huckleberry Hound, Chief Wiggum, Yogi Bear? Hah! Andy Griffith, Edward G. Robinson, Art Carney." All the characters mentioned to be "plagiarized" versions are Hanna-Barbera's except one (Chief Wiggum).
The Flintstones is so much an expy of The Honeymooners that Jackie Gleason threatened to sue Hanna-Barbera.
1974's These Are The Days was basically The Waltons animated. It is notable that unlike other HB 'period' pieces (The Flintstones, The Jetsons, and The Roman Holidays) in which the joke is 'what would modern day problems and things be like in those times', they wrote and animated it as realistically as possible for the period, further making it look like an expy of The Waltons.
These Are The Days was created by Earl Hamner Jr., creator of The Waltons.
Another H-B character, Snagglepuss, is an expy of Bert Lahr's portrayal of the Cowardly Lion in The Wizard of Oz. Lahr himself even threatened to block a commercial for Kellogg's Cocoa Krispies which had Snagglepuss, forcing Kellogg's to issue a disclaimer that Daws Butler is the voice of Snagglepuss, a rare instance where a voice actor is disclosed in commercials.
Mumbly reappeared in Scooby's All-Star Laff-a-Lympics, now partnered with a Dick Dastardly Expy called the Dread Baron. (At the time, Heatter-Quigley still owned the Wacky Races characters; Hanna-Barbera later bought the characters outright.) Oddly enough, Mumbly was a pre-existing character that predated Wacky Races, with exactly the same design he had in Laff-a-Lympics, although he was a good guy (and Columbo pastiche) in his series. The similarity was likely just conveniently coincidental for Hanna-Barbera.
The snickering dog who predated Wacky Races was Precious Pupp (1965). Muttley and Wacky Races predate Mumbly by eight years.
Both of them actualy appeared in the "Yogi Bear and the Magical Flight of the Spruce Goose" movie, where the Baron was actually voiced by Paul Winchell, Dick Dastardly's voice actor.
In Latin America, they just said "the hell with it" and called them Pierre Nodoyuna and Patán (the Latin American names of Dick Dastardly and Muttley).
An issue of the Laff-a-Lympics comic book revealed that the Dread Baron is Dick Dastardly's brother.
In Space Race which is basically Wacky RacesIN SPACE we have the Phantom Fink which is basically Dick Dastardly with a beard and a different dog.
Suzie Chan is essentially a Chinese-American version of Daphne in terms of appearance and temperament. The only difference is that Suzie, being somewhat savvier, avoids falling into the role of the Distressed Damsel.
Hanna-Barbera made a career of ripping themselves off to the point where no one else would even bother to. They even made a Yogi Bear expy, except it's about a polar bear trying to get cough medicine for his friend seal from a US arctic base.
Likewise Help! It's The Hair Bear Bunch!, Hair Bear seems to be Yogi except in a zoo, and threatened to have to leave it as opposed to the other way around. Both Hair and Yogi are generally more clever than their antagonist, and they hatch zany schemes.
