Werewolf Theme Naming

Even if werewolves are different from series to series, they tend to be easy to spot because of the one thing they typically have in common across all works: their meaningful names are almost always a reference to the werewolf myth.

Typically, your fictional werewolf will have his name based on...

The scientific name for the gray wolf, canis lupus
Foreign words for wolf, such as lobo.
Fenrir, the monstrous wolf from Norse Mythology
The German name Wolfgang
Romulus or Remus, the twin founders of Rome said to have been suckled from a wolf's teat.
Fangs or claws, because wolves have them.
The words "Moon" or "Silver", or variations thereof, sometimes in different languages (beware the woman named Luna).
Just the word wolf, because writers can be lazy sometimes.

Werewolves aren't required to have wolf-related names, but if you're in a supernatural setting and you meet a guy named Romulus Wolfgang, you can bet that he gets hairier when the full moon rises.

A subtrope of Meaningful Name and Our Werewolves Are Different

Examples of Werewolf Theme Naming include:

Comic Books

The Lobo Brothers and Maximus Lobo from the Marvel Universe.
Anthony Lupus from the The DCU.
Scud the Disposable Assassin made fun of this: Scud has to hijack a space shuttle, one of whose members is secretly a werewolf. All of the astronauts have names like "Lupin," "Mike Wolfman," "Ted Howls-at-the-moon" and so on, just to obfuscate which of them it is.
Jack Russell from Werewolf By Night in the Marvel Universe shares his name with a breed of terrier.

Film

Averted in the original 1941 film The Wolf Man in which Lon Chaney's character is plain old "Larry Talbot."
- Well, it is far-fetched, but Talbot is an kind of dog and the domesticated dog is a wolf sub-spieces... which would make him the Trope Codifier.
Subverted in the Underworld movie series in that the main character Selene (named after a moon goddess) is not a werewolf, but a vampire. What makes this example ironic is that she hates werewolves with such a passion that she became perhaps the best werewolf-hunter in her city.

Literature

Remus Lupin and Fenrir Greyback from the Harry Potter series.
Canis Wolfborn (and every Space Wolf that doesn't have a Viking name). And then there are those like Ragnar Blackmane.
Discworld:
- Averted: Big Fido the poodle spends his time extolling the virtues of wild wolves, claiming they have names like Quickfang. The actual werewolf knows this is BS, as wolves don't think of themselves that way. Indeed, in The Fifth Elephant we learn they have names like Arsehole.
- The evil werewolf in The Fifth Elephant is named Wolfgang, though.
Mocked in Curse of the Wolfgirl by Kalix. Kalix, a real werewolf from family of werewolves who have no wolf-y sounding names finds a comic about a werewolf called "Arabella Wolf" and finds it incredibly unlikely and insulting that a girl is called "wolf" long before she becomes a werewolf.
Anthony Boucher's The Compleat Werewolf has a wizard lampshade the hell out of this, pointing out that the titular character is named "Wolf Wolfe".

Live-Action TV

The Munsters' wolfboy son, Edward Wolfgang Munster.
Oz, from Buffy the Vampire Slayer, is in a band named Dingoes Ate My Baby, or "Dingoes" (read: wild dog) for short. The band existed long before Oz became a werewolf, though: it was mentioned in the unaired pilot, while Oz wasn't bitten until halfway through season 2.
In Kamen Rider 555, there's Takumi Inui. Inu means dog, and we find out why it's a Meaningful Name mid-season. The same goes for his Kamen Rider Decade counterpart, Takumi Ogami, which is close to Okami, meaning wolf.

Manga and Anime

Akira Inugami from Wolf Guy Wolfen Crest. 'Inu' meaning dog, and 'gami' being a variant of 'kami', meaning spirit/daemon. So effectively wolf-spirit.
Kiba (fang), Toboe (howl), Hige (whisker), and Tsume (claw) from Wolf's Rain. They're not exactly werewolves so much as wolves psychically disguised as humans, but same difference.

Toys

Monster High has Clawdeen Wolf, her brother Clawd, and her sister Howleen.

Video Games

Golden Sun: The Lost Age has the city of Garoh (a reference to the French word garou), which is populated entirely by werewolves.
Fenrich from Disgaea 4: A Promise Unforgotten
Jon Talbain is named "Gallon" in Japan-"Flench" for "werewolf."
Fang from Lost Vikings is a werewolf.
Touhou has Keine Kamishirasawa, a were-Hakutaku, whose surname can also be read as "ue-hakutaku".
The Elder Scrolls V: Skyrim have the twin Companions members Farkas and Vilkas, which both mean 'wolf' in Hungarian and Lithuanian respectively.
Subverted with Fenris in Dragon Age II, who is only a wolf in a metaphorical sense.

Web Comics

Samantha Wolf in The Wotch, better known as "Wolfie" to her friends. Jason thinks it's way too obvious that she's the werewolf, but he's wrong.
Skin Horse has Julie Rome (as in Romulus), Sergeant Willoughby (as in Joan Aiken's The Wolves Of Willoughby Chase) and Lucy (sounds a bit like lupine or lycan). There's even a theme-named werewolf victim: Private Hood.

Western Animation

Howler from Drak Pack.
