An episode of Mighty Max, "Fly By Night", took Our Vampires Are Different to its natural extreme by featuring a female vampire, Countess Musca, who ignored almost all of these vampire tropes (aside from the obvious blood-drinking). To top it all off, instead of a bat, she turned into a giant horsefly.
In Count Duckula, a vampire who has been killed can be brought back by a once-a-century secret ritual. In the most recent ritual, tomato ketchup was accidentally used instead of blood, resulting in the title character becoming a vegetarian. And he's a duck, which is pretty different all on its own.
In Scooby-Doo! and the Reluctant Werewolf, the Big Bad is a vampire named Count Dracula. However, he is comically inept at his goal of making Shaggy lose the Monster Car Road race. He did find a way to counter the sun weakness, by wearing sunscreen.
Likewise with his partner (wife?) Vanna-pira. Unlike the green skinned Dracula, you could mistake her for human. It's only her yellow eyes and grown out nails that peg her as a vampire.
Buzz Lightyear of Star Command has a robotic vampire called NOS-4-A2 who drains the energy of robots and other machinery as opposed to drinking blood. He also has mind control abilities over said machinery. In combination with radiation from a certain moon, it also can turn humans into feral mechanical "wire-wolves".
In an episode of Attack of the Killer Tomatoes!, a vampiric tomato was going to suck blood from someone's neck until the local censor said that sucking blood wasn't "nice" enough, and suggested that he try kissing instead. He does, but that turns her into a vampire anyway, and starts a race of vampires who are obsessed with smooching their victims instead of drinking their blood. Also, the transformation comes with a costume change and adopting a Transylvanian accent.
An episode of Moville Mysteries had the main characters believing an exterminator was a vampire... and he was, sort of. He was actually the "adopted son" of a group of vampiric mosquitoes led by a human-sized, repulsive queen who just happened to sleep in a coffin. The exterminator's Game Face had him adopt insect-like traits and he winds up being ripped apart and eaten by a swarm of hungry frogs. The queen and her spawn are destroyed by a giant, makeshift bug zapper.
On Adventure Time,Marceline the Vampire Queencan drink blood, but actually only needs to eat the color red (which she can suck out of anything, leaving it gray). This does not necessarily make her a Friendly Neighborhood Vampire, however—-she seems to like the title characters, but once mad, she transforms into a horrific bat-monster and tries to kill you really fast. Also, she can apparently enter houses without being invited and has extra powers like necromancy and invisibility, though sunlight still hurts her. She may have been born a vampire, too, since we see her a child in a few episodes.
Her dad, on the other hand... well, maybe he used to be a vampire. Now he's a soul-sucking Humanoid Abomination who rules a dimension of chaos, has a second head in his throat, and can grow out when he gets more powerful. And it looks nothing like a bat.
She started out half-demon and later became a vampire on top of that. And became the Vampire Queen by killing the Vampire King. Her father's just a demon, not a vampire.
In the Halloween Episode of DuckTales, "Ducky Horror Picture Show", Scrooge unknowingly allows a bunch of monsters into his new community center, and his home, one of which being a Vampire. It is discovered when Hewey, Dewey, and Louie bring him apples, that he eats those and does not bite people or animals. They keep his teeth shiny, you know.
Codename: Kids Next Door features the villain Count Spankulot who, well, spanks children. Doing so without his gloves will transform the victim into a spanking vampire himself, with the only way to cure the victim is for him to spank the Count. (He only does this to kids who really make him angry, as he did to Numbuh One in retaliation for sending him to jail.) However, he still has the traditional weakness to garlic. (But not to sunlight.)
The Batman vs. Dracula has a version of Dracula who drains blood from people and makes them into "Lost Ones" who are minion vampires but can be turned back to human by scientific means. It's stated that he can kill people by draining their blood but it never happens, this being a cartoon where Nobody Can Die. Minion vampires always look like pale monstrous creatures, but Dracula himself can look human when he feeds enough.
It should be noted that among his minions is a vampire Joker, and this continuity's version of the Joker is a feral gorilla-like prop comic, build like the original Beast and with lime green dreds. He robs a blood bank—which consists of a dramatically-lit warehouse lined with eighty-foot shelves of glass jars of blood. The Batman captures him and uses him as the experimental rat as he tries to cure vampirism.
Ironic as it seems, in an episode of the Superfriends called "Attack of the Vampires", the vampires didn't bite, but shot laser beams from their eyes to make vampires in numberous amounts! How did the Caped Crusader and the Boy Wonder escape from joining them? They had visited a cave filled with normal bats by accident searching for the vampires!
In Darkwing Duck, the vampire is a huge potato. Talk about different. It seems to mostly be a roaring beast, and when it captures its victims and does whatever it does offscreen, the result is a character with an intense desire for potato-based foods, Mind-Control Eyes, no will other than to sit around and watch TV (a couch potato), and sprouts coming out of their heads. Its weakness is someone saying "potato backwards" (literally, "potato backwards", not "otatop") while shaking out the pollen of the particular plant that its creator, Bushroot, happens to be. (Incidentally, on his way into the forest, he runs into some hicks who perform some... interesting vampahr tests on him note dropping him from a great height because apparently, vampahrs bayounce; force-feeding him super-hot peppers because vampahrs don't lahk 'em....)
Frylock (using his scanning device): The call is coming from inside that school bus!
Shake: Inside the bus? It is the bus! The bus of the undead! Vampires!
Frylock: I'm not detecting any vampiritic activity. Besides, it's 2 o' clock in the afternoon.
Shake: It's... it's a reverse vampire! They crave the sun! Love it. They love to get tans.
Frylock: Really? And where do they come from?
Shake: Uh... Tansylvania?
Frylock: Oh, no. No, no, no way in the world!
Shake: See the wheels? Those are the markings.
Frylock: Where do you get this stuff?
A true example is Marcula, the Aqua Teen's landlord.
The Looney Tunes cartoon, Transylvania 6-5000, features Count Bloodcount. He tries various times to kill Bugs Bunny, only to fall victim to the rabbit saying both "Abracadabra" and "Hocus Pocus", which transforms the vampire into and out of the form of a bat at inopportune moments. Bugs catches on to what is happening and uses these magic words to ultimately defeat the Count.
Count Bloodcount: I am a vampire! Bugs: Oh, yeah? Well, abracadabra! (umpire outfit appears on him) I'm an umpire! Count Bloodcount: Hocus pocus! (turns into a bat) I'm a bat! Bugs: Okay, I'm a bat, too. Abracadabra! (turns into a baseball bat) Count Bloodcount:(puts on a pair of glasses)You wouldn't hit a bat with glasses on, would you? (Bugs as a baseball bat hits the-Count-turned-bat on the head, knocking it out)
The ABC Weekend Special Bunnicula the Vampire Rabbit.
Archie's Weird Mysteries gave vampires a three episode arc ("Scarlet Night", "I Was A Teenage Vampire", "Halloween of Horror"). Transformation is immediate and results in Transhuman Treachery level morality shift. Transformation also results in pale white skin, red eyes, and the usual fangs. The condition can be cured by killing the victim's sire within an hour or the head vampire at any time. They have the abilities of flight, super strength, and changing into mist. There's also a mystic amulet that can destroy them with a laser beam, but it must be used by "the chosen one".
Though they never appeared in the show, some promotional materials state the Ben 10 universe once had a species of vampire-like aliens called Vladites, who used to share the planet of Anur Transyl with the Transylians. They were apparently exterminated by the Transylians before the story started, though.
Michael Mourningstar (AKA Darkstar), one of the villains from Ben 10: Alien Force, possess characteristics similar to a vampire.
Believe it or not, Malware from Omniverse is the Mechomorph equivalent of a vampire, draining his fellow Mechomorphs into lifeless husks.
Extreme Ghostbusters dealt with clown vampires, only these vampires fed on laughter instead of blood. They still used the traditional method of passing their vampirism into new victims, as Eduardo painfully found out.
My Little Pony: Friendship Is Magic: In the episode "Bats!", the characters have to deal with vampire fruit bats that are preying on Applejack's apple crop. Their plan to hypnotize the bats into not feeding on the apples succeeds, only for their lust to transfer to Fluttershy, turning her into a apple-sucking vampire as well.
