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.
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.
Starscream is kinda sorta a zombie robot, except he has complete sentience when he is brought back from the dead.
The new, even explodier incarnation of Wheeljack, a Samurai Cowboy Robot who specialises in dual katana and grenades. As if that weren't enough, he's also an Ace Pilot - by virtue of shooting down 'cons while flying his spaceship, rather than just being a spaceship.
Transformers Prime is the first Transformers continuity to use genuine Robot Zombies, not just some form of mind control. So I guess that's the complete set then?
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.
Dexter's 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.
Irwin, who's 1/2 mummy, 1/4 vampire, and 22/7 nerd, which is a result of having Dracula as a grandfather, a dhampyr as a father, and a mummy as a mother.
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.
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 Cloud Cuckoo Lander).
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...
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.
Sadly, Robot Pirate Island turns out to be an island where robots fight pirates, not an island full of robot pirates, making it instead an example of a related trope.
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?)
The "wizard alien" from "Sexual Healing." In this episode, the American government is trying to figure out what caused the "recent" trend of successful men having affairs with lots of women. Instead of just admitting that this kind of thing has happened throughout history and that most men have similar urges, the government blames it on a wizard alien living in Independence Hall.When a soldier calls BS on this, the other soldiers take him away, dress him up as a wizard alien, and have Kyle and Butters shoot him dead.
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: The 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".
The New Adventures of Winnie the Pooh had one episode where the heroes had to deal with a gang of horse thieves. They weren't called that for stealing horses but for being thieves and horses.
The Filmation Ghostbusters cartoon had the villainous minions Scared Stiff and Long John Scarechrome. The former is a robot ghost that resembles a skeleton and the latter is a technology-themed ghost pirate from the future.
