Western Animation: Wile E. Coyote and the Road Runner aka: Road Runner
"Now we're going to watch one of my favorite cartoons about a pathetic Coyote who spends his life in the futile pursuit of a sadistic roadrunner, who mocks him and laughs at him as he's repeatedly crushed and maimed! I hope you enjoy it!"
An extremely popular series of Looney Tunes short subjects made by Chuck Jones during The Golden Age of Animation, the Wile E. Coyote and Road Runner shorts are centered on the titular duo as the smart but obsessive coyote does everything within his power (and uses everything within the ACME catalog) to capture the elusive Road Runner for dinner. Despite the penchant for formula and sporadic entries in the original theatrical lineup, the shorts have remained extremely popular to this day, lasting for 40 shorts in the classic era, with new shorts being created for theaters!They have made a comeback via CGI in The Looney Tunes Show.
Acme Products: Of course, it's a mystery how Wile E. can pay for all the stuff he orders from them, and a bigger mystery why he continues to do so, seeing as nine times out of ten, their products are the reason he fails. (One Cartoon Network ad hints that he's the QA tester for the company, but another one has him sue the company over all the malfunctioning equipment, gaining a prime-time slot as a settlement.)
Art Evolution: The designs of the two characters did change a bit over the years, but this trope was more evident in the background designs. The first three cartoons had scenic, but fairly bland-looking backgrounds, which gave way to more abstract designs starting with Maurice Noble's arrival. They gradually got more and more unusual, eventually leading to some flat-out weird scenery in "Gee Whiz-z-z-z-z-z-z" before settling down into a more consistent style from 1957 onwards.
Iron Butt Monkey: Even for a Warner Brothers cartoon, it's amazing what the Coyote goes through - and then gets up and goes right back in.
Canis Latinicus: Both parties receive a new genus/species name in this style before each short ("To Beep or Not to Beep" being the exception). In one short ("Soup or Sonic"), even the Roadrunner's beeps get a scientific name: "beepus-beepus".
Though "The Whizzard of Ow" showed the actual scientific names, Geococcyx Californianus (greater roadrunner) and Canis Latrans (coyote).
"Stop! Look! and Hasten!" also features a cameo by a Burmese Tiger ("Surprisibus Surprisibus")
Conspicuous Trenchcoat: When Wile E. gets hold off a Spy Kit in "Sugar and Spies", he starts wearing a black trenchcoat and hat. In the middle of the desert.
Crossover: Two, on a technicality. "Hare-breadth Hurry" has Bugs Bunny filling in for a sidelined Road Runner, while "The Wild Chase" has a cannonball race between the Road Runner and Speedy Gonzales, with the Coyote and Sylvester in pursuit.
Wile E. also crossed into a few Bugs Bunny cartoons as well. These are where the "Wile E. Coyote, Super-Genius" persona comes from.
Depending on the Writer: The Road Runner is variably either a wild creature going simply about its life and avoiding getting caught, or a sadistic trickster who deliberately sabotages the Coyote's plans and seems to enjoy seeing him get hurt.
Everyone Has Standards: In one cartoon, Wile E. takes a massive tumble, falling down several cliffs, sucked through pipes, over waterfalls, and is hit by a truck, before finally coming to a stop at the top of a cliff, breathing hard and clutching his chest. The Road Runner runs up behind him and has a chance to scare him off the cliff like he usually does, but he holds a sign up that says "I just don't have the heart", and runs off again.
Some later shorts show a possible method of survival, opening with the Coyote trying to eat a rock or a cactus, failing, then going in pursuit of the Roadrunner. One episode even opened with the Coyote successfully eating a lizard (on screen: "Coyote (Eatibus anythingus)"). The Roadrunner is probably the only thing around with any real meat on it, so he's willing to go to extraordinary lengths to get just one filling meal.
Flat Character: The Road Runner himself is nondescript in personality, with the shorts choosing to give focus to Wile E. Coyote instead.
Arguably this is no longer the case in The Looney Tunes Show, where The Road Runner is portrayed as finding Wile E. Coyote's efforts playfully amusing; he gets as close to the Coyote as possible, including posing for photos with him, and in the short "Heavy Metal" he repeatedly runs back through the same tunnel to encourage the Coyote to chase him again.
But, as the quote above shows, the Road Runner of the original shorts can easily be viewed as sadistic, making fun of the Coyote's suffering, kind of like Tweety for Sylvester.
Friendly Enemy: What the Road Runner regards Coyote as. He's not oblivious to the fact Wile E. wants to kill and eat him, but always 'Beeps' cheerfully to him, and is rarely malicious and never openly hostile towards to the Coyote.
Getting Crap Past the Radar: In one short, Wile E.'s scientific name was given as "Hardheadipus oedipus", (i.e. hard-headed motherfucker). Meanwhile, the Road Runner's scientific name was given as "Batoutahelius".
Hero Antagonist: The Road Runner can be considered the hero of this short, being hunted after by a hungry predator. However his character is kept deliberately flat and Out of Focus in each short so that the audience's sympathy is instead with Wile E Coyote.
Hoist by His Own Petard: Seriously, the Trope could practically be called "Wile E. Coyote Syndrome" it happens to him so often.
Hollywood Magnetism: Wile E. Coyote got bitten by this once. In his attempt to catch Bugs Bunny with an iron carrot, his super-magnet ended up attracting all sorts of metal junk instead, including the Eiffel Tower, an ocean liner and finally a ballistic missile, which blew him to kingdom come.
He also got the Road Runner to eat some iron pellets disguised as birdseed, then tried to capture him with a giant magnet. The magnet attracted a giant barrel of TNT instead.
Mr. Exposition: Wile E. becomes this in one cartoon where two kids watching the cartoon on television wonder why he wants to eat the Road Runner. He explains in detail - with visual aids - just why road runners are considers such a delicacy to coyotes.
Racing The Train: In the cartoon "Zipping Along," the establishing scene features the bird zipping along a train, although he leaves the road and never attempts to beat the train to the crossing.
The Road Runner's observation of safety is reprised in a later Operation:Lifesaver commercial aimed at children. In it, the Road Runner, despite his ability to put some extra speed in his already fast run, is aware of safety rules concerning railroad crossings and stops to allow a train to pass. Of course, Wile E. Coyote arrogantly doesn't, and he (once again) is crushed beneath another oncoming train.
Recycled IN SPACE!: It's a cat and mouse cartoon IN THE DESERT! AND THE VILLAIN IS WHO EARNS OUR SYMPATHY!
Strictly Formula: Popular as the shorts are, they're best watched in small doses, as they tend to feel really, really samey if you watch all of them back to back.
Suddenly Voiced: At those rare occasions Wile E. does talk, he speaks in a very refined voice, as well as revealing the fact that he's an Insufferable Genius. However, he always speaks when he's up against Bugs (except for one short which doesn't really count, as Bugs is taking over for the Roadrunner in that one).
"Y'know, it's amazin' the trouble this joker goes to to get a square meal."
Surprise Jump: The Road Runner frequently does this to the Coyote. Subverted at the end of "Zoom and Bored" where the Coyote had just endured a harrowing journey involving a harpoon gun and had landed safely on solid ground. The Road Runner runs up behind him as usual... but then "says" he doesn't have the heart this time, and leaves.
Team Rocket Wins: Yes, the Coyote catches the Road Runner at one point... but the gag makes it impossible for him to actually eat the bird. He even lampshades it by asking the audience what he should do now.
And AGAIN in the CGI short "Heartbreak Bridge", where The Road Runner willingly and happily jumps into the Coyote's arms, but this unbalances the bridge they are both standing on, and to save himself the Coyote has to throw the Road Runner to the other side. The rest of the short is the Coyote attempting to keep the bridge balanced while the Road Runner tries to tip it up. Doesn't work out.
Most of the Road Runner shorts made by parody comedians have the Coyote finally catching the Road Runner. A Seth MacFarlane short called "Die Sweet Roadrunner, Die", has the coyote finally catching and eating the bird. But with his purpose in life lost he gets horribly bored and depressed and attempts suicide (hysterically enough, he does so with an ACME product). Then he does find a purpose in life and becomes a Born-Again Christian.
Technicolor Eyes: In the shorts by Matthew O'Callaghan, Wile E.'s are red, and the Road Runner's are turquoise.
Throw the Pin: Wile E. does this in "Beep Beep", leaving him with a grenade in his teeth.
The Voiceless: Both of them. Wile E. does speak during four of his five appearances with Bugs Bunny, and again when explaining to two young boys why he wants to eat the road runner.
And in one cartoon, as he's walking off screen, mangled out of shape, he gives us a deadpan "ouch."
If you were to count the Road Runner's "BEEP BEEP" as a voice, he would fall under The Unintelligible.
Truth in Television: In Just Plane Beep when Wile E. shoots the propeller of his biplane off trying to hit the road runner. That was a real problem in WWI before the interrupter gear was invented, and one solution (as was also shown) was to put armor plating on the propeller.
Villain Protagonist: Wile E. Coyote is trying to eat the Road Runner, and is therefore ostensibly the bad guy. But he's just so adorably persistent in how he goes about it that you can't help but root for him.
Chuck Jones in fact had it as written lore that all sympathy must be with the Coyote.
Villainous Underdog: The cartoons are built around this concept, with the smart, but horribly unlucky coyote being thoroughly overmatched by the super fast, equally smart, and and ungodly fortunate Road Runner. Physics itself was always on the Road Runner's side, meaning Wile E's schemes were doomed from the start.
Weaponized Car: Wile E. builds one in "Sugar and Spies". It includes machine guns, a cannon and an ejector seat.
Written Sound Effect: "Chariots of Fur" (Chuck Jones's last Road Runner short) uses these quite a bit, but only once does it do something creative with them — when the Coyote disguises himself as a cactus and tries to garb the Road Runner, but the Road Runner avoids him, the Coyote accidentally wraps his arms around himself in the process, and the smoke trail the Road Runner left behind turns into a "!!YEE-OOWW!!"
