Fluffy the Vampire Pointer (or Fluffy for short) is a monster hunter/slayer, and she targets evil creatures to hunt down and destroy to protect the world from their wrath.
Fluffy's history is mostly unknown. She seems to have no owner(s) or anywhere to stay. However, her monster knowledge (and access to the book with a page on Bunnicula), calm demeanor, and Kung-Fu training, obviously means she more than likely had an owner at some point. But, as Mina pointed out, she has no tags, which could possibly mean she's a stray or had an owner that passed away/abandoned her. Baron Karloff implied there is more than one vampire pointer, making it possible that Fluffy is the current holder of the title.
At some point, she captured a vampire and was photographed by Baron Karloff. He sent her many letters, but she ignored them all. When Karloff became a vampire, she considered him a threat. At some point, she defeated a manticore and several harpies he had sent to defeat her.
In the episode she appears in, she was an enemy of Bunnicula and tried to hunt down Bunnicula throughout the episode, until realizing he cares about his family and decides to go and hunt other such monsters and creatures of the night; except the cool ones. She later went to Bunnicula for help with defeating Baron Karloff, as she had the flu. Harold had her stay behind and they fought Baron Karloff at the pet cemetery. Fluffy went to the cemetery upon seeing the fire and lightning created by Bunnicula's giant monster form. However, she was defeated by Rip and thrown at Baron Karloff, breaking his staff. After Bunnicula defeated Rip, she took Baron Karloff to vampire prison, and they started to talk about the time Fluffy beat the manticore and the harpies.
Fluffy is a black and brown Doberman Pinscher. She has yellow eyes with blue pupils, two brown circles around them, brown coloring around her muzzle (with a check-shaped indentation around her eyes), and a triangle-shaped downward patch of fur connected to her muzzle that stretches down her neck. She has a small, shiny, black nose. She has multiple sharp, white teeth in her mouth, though four fangs can be seen when she talks and one protrudes from her mouth when closed. On her chest is a four-pointed marking, somewhat resembling a tulip. Her legs are all two-tone with the same brown as the rest of her body. Being a Doberman, her body shape is slim and slick, her ears pointed, and has a rounded stub tail. She wears a dark reddish-brown collar around her neck. She usually has a serious/determined look on her face.
Fluffy always seems to be very diligent and focused on her job at hand. She tends to get annoyed when anyone gets in her way (Harold) or a plan she has fails. She seems to dislike being treated like a pet/being played with (as such when Mina rubs her belly and attempts to feed her). More than likely, finishing her tasks at hand is all she worries about. She seems to be very strict and serious.
She has proven very selfless and kind, as she attempted to sacrifice herself to save Harold and Chester from the stakes she set up for Bunnicula (which luckily, he saved them all from at the last second). Harold ended up believing she saved them, though.
She acts like a mixture of Batman and Buffy the Vampire Slayer, who she seems to be based off of. She also seems to act like Van Helsing, hunting down Dracula (or Bunnicula, in this case).
She doesn't mind to do odd forms of attacking when going after her prey (such as sucking up and presumably eating Bunnicula). She also seems to be able to jump high (to get from a ceiling vent), is very strong (is able to lift Harold, a dog much larger and heavier than herself and is able to pull the vent covering off in one jump) and pretty quick (when she smacks him with a flyswatter). Fluffy is also known as the "Kung-Fu Dog" because of her bouts with Harold (repeatedly flipping him over/out of the way). When she targets her prey, she'll stop and "point" at them, like that of a Pointer (which is strange, since she is a Doberman Pinscher, which are not known for this trait).
Initially, she tried to hunt him for his vampire nature. To that end, she tried to hunt down Bunnicula throughout the episode, until realizing he cares about his family and sees not all monsters are evil. Although she goes to resume hunting other monsters and creatures of the night, she makes an exception for the cool ones. She now considers Bunnicula a friend, as she went to him for help with stopping Baron Karloff.
Harold seems to irritate her the most with his constant attempts at flirting with her, but in the end, she seems to be on okay terms with him. In Harold, the Vampire Pointer, she implied that she may reciprocate his feelings.
Chester was worried as she hunted Bunnicula. He tried to dissuade her about him but she didn't consider until realizing he cares about his family and sees not all monsters are evil. At the end, she seems to be on okay terms with him.
She does not get along with Mina, despite Mina's good intentions. When Mina rubbed her belly and tried to feed her, Fluffy became paranoid that she would be turned into one of Bunnicula's "minions" and ran away. However, since she is now aware that Bunnicula is not evil, it is unknown how she feels about Mina currently.
She mostly ignored Karloff before he became a vampire, as she ignored all of his letters. However, after he became a vampire, she considered him a threat and battled the monsters he summoned multiple times. She became somewhat friendly to him after he tried to save her from Rip, but still took him to vampire prison and acted cold to him on the way there.
She and Rip are bitter enemies after what the grave walker did to her. However, Fluffy did not attack Rip after Bunnicula defeated him.
- She seems to be based on various characters, mostly Buffy the Vampire Slayer ("Fluffy the Vampire Pointer"), Batman (the deep-voiced monologue at the beginning and walking around in the shadows), and Abraham Van Helsing.
- She is voiced by Sumalee Montano, who did a similar voice for Arcee from Transformers Prime.
