A design for an Animated incarnation of the character (intended for the unproduced 4th season) made him a pirate robot tank with an undead motif.
The latest Rule Of Cool characters are in Transformers Animated:
Prowl - a Robot-Ninja. He's a Friend to All Living Things, an alien, has Cool Shades, and his transformation is a cop's motorcycle. He has been a medic, a Bounty Hunter, a zombie, a Samurai, psychic, almost dead, a ghost in the machine, on the moon, can use an Improvised Weapon, and ended his career as an actual ghost.
Lockdown - his Robot-Pirate rival. He's a full-time bounty hunter, he collects trophies of his captures, his alt mode is a huge muscle car that's a mashup between a '60s Cougar and an '80s Corvette, he has what a human would call tattoos, a hook, a chainsaw, his own spaceship, and has worn a robot sized poncho. On the moon. He seems to also gain new abilities every time we see him - but then, he is a sucker for upgrades. He was designed to look a little like an undertaker with a skull for a head. Oh, and the latest version of his toy is on fire. We later find out in "Five Servos of Doom" that he is also a ninja (though he quit and turned traitor before completing his training). Given his Hook Hand and death motif, he may be one of the few true literal examples. Oh, and those upgrades we mentioned? They tend to come off of other Transformers, so you could also count him as a cannibal.
Then there's Bulkhead, a demolition vehicle, Gentle Giant, artist, and Genius Ditz with space bridge technology.
Soundwave starts a robot uprising and wields a guitar and a keytar that double as sonic weaponry and mind control devices, all while wearing Cool Shades. And his sonic weapons can transform into robots as well. Robot animals, no less.
Predictably, the show Gargoyles contains gargoyles, including samurai gargoyles and gargoyle-bots. The undisputed winner, however, is Coldstone, an undead cyborg gargoyle.
An undead cyborg gargoyle with three souls in one body! Souls which, incidentally, have a Sibling Triangle.
Also the Mutates, who are human-cat-bat-eel hybrid mutants designed to look like gargoyles.
Megas XLR features another example of zombie robots in the episode "Junk in the Trunk." Guess no combination is truly impossible.
Codename Kids Next Door: the KND once had to face an A.D.U.L.T in a 10 foot-tall, heavily armored mechanized suit with guns, missiles, and two flaming chainsaws.
Dexters Laboratory used this in the Show Within a Show/Three Shorts companion, The Justice Friends, combining hard rock legend Eddie Van Halen with Thor to create "Val Hallen, the Viking God of Rock." Easily the coolest super hero in history, except possible "Monkey" the superpowered monkey from the same show.
Dino Riders: Two races of aliens fighting with high-tech weapons while riding dinosaurs!
The Bots Master had cookbots, sports bots, and yes, a ninja bot.
In one episode of ReBoot, one game crashed, and the User loaded another game on top of it, resulting in a mishmash of a dinosaur adventure and a military game, notably including Pterodactyl jets and a Tankasaurus Rex.
And in one of the video games, robot monkey ninjas.
One episode went out of its way to invoke this with "Monkey Ninjas IN SPACE!". (The best thing about it was the title.) In a later episode, a director independently tries to use it as a movie idea, only to be shut down with a "been there, done that" reaction.
The Simpsons mentioned this, when Homer stood up against Mr. Burns:
Mr. Burns: I suggest you leave immediately. Homer: Or what? You'll release the dogs? Or the bees? Or the dogs with bees in their mouths, and when they bark they shoot bees at you?
In a deleted scene, Burns goes on to sic a robotic Richard Simmons on Homer.
It is actually possible for characters to create the-dogs-with-bees-in-their-mouths-and-when-they-bark-they-shoot-bees-at-you in Mage The Ascension and Mage The Awakening — it just needs 3 dots of Life magic and a normal dog, or 5 if you have to make the dog too.
Poochie from Itchy and Scratchy is intended to be this, as he introduces himself as being "half Joe Camel and a third Fonzarelli, I'm a kung-fu hippie, from gangsta city, I'm a rappin' surfer." However, he's actually a very unpopular character because of this, and annoys the viewers, the former Trope Namer for The Poochie (now Shoo Out The New Guy).
The Invader Zim episode "Zim Eats Waffles" features a flesh-eating robot demon squid that summons an army of cyborg zombie soldiers. Other episodes have mention of similar things, for example laser weasels and a mongoose dog (although the latter was courtesy of the series Cloudcuckoolander).
In the Venture Bros. episode "Eeny Meeny Miney... Magic!", Brock Samson's Joy Can vision includes ninjas raining from the sky, cowboys with flamethrowers riding Tyrannosaurs, polar bears on motorcycles, and SCUBA divers with machine guns. And he has to fight them all. And he kills them all, winding up on a mountain of ninja/cowboy/dinosaur/bear corpses.
In the episode "Shadowman 9: In the Cradle of Destiny", the Monarch narrates one of his early attacks on the Venture compound, attributing his failure to Venture's "army of ex-navy seal cyborg ninja witches". The simultaneous flashback shows, however, that he was defeated by Venture's lone bodyguard Myra. Helper helped too...
"These guys like their system. It's what they do. You take that away and you are looking at a bunch of pissed off nutbags with ray-guns and giant... I dunno, a giant octopus/tank with laser-eyes"
Fakeout: "Hey, it's that ghost pirate! Who's not a ghost. Or even a pirate, really."
Then there's the time Brock had to fight those Vatican karate gorillas...
Hilariously parodied on Foster's Home for Imaginary Friends, with Bloo's ridiculously over the top contest film T-Rexatron Alienwolf 3: A Prequel in Time: The Unrelenting.
Plastic Man: Are you seeing what I'm seeing? Because I'm seeing gorillas, riding pterodactyls... with harpoon guns... stealing a boat.
The show also has a scene where Batman teams up with Vampire Batman, Cowboy Batman, Psychic Batman, Robot Batman, Gorilla Batman, and Space Batman. Words cannot describe how awesome it was.
Later, we got Batman being chased by skiing ninjas with lasers.
REAL HOLOGRAPHIC SIMULATED EVIL LINCOLN IS BAAAAAAAAAAACCKKK!!!!!
And then there's also General Major Webelo Zapp Brannigan.
At some point in the '90s, there was a CG show called Van Pires. In this show, the protagonists would fuse with various vehicles to combat other vehicles who turned into giant robots who woke up after dark drained normal vehicles of fuel (the Vanpires in question). They did every Saturday morning cliche in the book, but... man, mid-'90s CG cyborg car robot vampire hunters!
Sponge Bob Square Pants, in "The Idiot Box", mentions Robot Pirate Island, and Squidward wants to arm wrestle with cowboys on the moon.
South Park had a fabled discussion (among the members of KORN) over whether the apparitions of the episode were pirates who died and became ghosts, or ghosts who died and became pirates.
In one of the episode commentaries, an idea for an episode was mentioned involving a zombie werpechaun, or a leprechaun that was bit by a vampire and a werewolf who then died and came back as a zombie.
One news report was given by a midget in a bikini. (I mean, come on: Midgets are cool. Bikinis are cool. Put them together and you've got, like, a nuclear explosion of coolness.) Another was given by a Japanese man who looked kind of like Ricardo Montalban.
Manbearpig. Half man. Half bear.... Half pig.
No, it's actually half man, half bear-pig. (Or is that half pig, half bear-man?)
But all this pales in comparison to "Imaginationland", a mythical realm where every fictional character ever created in history lives together in some sort of Toontown on steroids. Their "Council of Nine" alone includes Luke Skywalker, Morpheus from The Matrix, Wonder Woman and Popeye. And where else could you see Santa Claus slaughtering Captain Hook?
There's an episode in Star Wars: Clone Wars that has three Jedi and a bunch of clone troopers fight alien bug warriors who are also zombies.
[adult swim] once spent a week talking about a hypothetical battle between a flying shark and a flying crocodile.
Aqua Teen Hunger Force features The Cybernetic Ghost of Christmas Past from the Future. The outrageous stories he tells also fall under this trope. In his first appearance, his stories are about a war between toy-making elves from "the red planet" and a large prehistoric ape who is actually Santa Claus (and for some reason, he also explains where baby robots come from). In his second appearance, he talks about hyper-evolved chickens who take over the world in the future.
The Mega Man series featured many unique robots, including some mentioned on the Video Games page, but "Night of the Living Monster Bots" deserves special recognition.
Parodied in Avatar The Last Airbender. All animals in the fictional setting are the combination of two or more real life animals; e.g., bat-wolves, platypus-bears, duck-turtles. The king of the Earth Kingdom is holding a party in honour of his pet bear, Bosco, and sends out invitations, the main characters, when reading the invitation, ask whether it's a string of bear hybrids. When they are told it's just a simple plain bear, they find the concept 'just weird'.
In the Powerpuff Girls episode "Him Diddle Riddle", HIM threatens to dump Ms. Keane into "this vat of boiling sharks".
