Archie's Weird Mysteries: Turning into a werewolf requires a wolf bite, the full moon, and possession of a pentagram ( which is only defined as a "five-pointed star", so a sheriff's badge works just fine).

The interesting thing about the wolf bite is that it does not seem that a full wolf is needed, as a wolfdog that is mostly dog will do.

They eat homework to feed, and bad homework (such as Numbuh 4's) is poison to them.

Even within the show, werewolves were different. One episode of the series featured another werewolf who transformed by way of a "Werewolf Secret Formula", and who was nothing like the Funny Animal-ish title character, instead having more of a classic Wolf ManLon Chaney Jr. look. During that episode one of the other heroes accidentally drank the formula, and turned into a werewolf that was a hybrid of the two, looking more like a wolf man, but acting like Fangface.
Freakazoid! did a parody of the original The Wolf Man with an obvious Lon Chaney Jr. parody coming to Dexter for help with his werewolf problem.

In a direct parody of An American Werewolf in London (and Turbo Teen), the episode "The Honking" has a curse that can turn any mild-mannered robot into a werecar. Unlike the hovercars the characters in the show are familiar with, these cars are "crawling around on round rubber feet... like a wolf!" The Spanish dub correctly calls them "coche lobo", car-wolf (as opposed to "hombre lobo", werewolf). Werecar implies that the monster is some sort of mix between a man ("were") and a car, and Bender is a Man-bot.
Werewolves themselves are confirmed to exist in the episode "Related to Items You've Viewed", apparently as the traditional wolf-like humanoids working under the full moon.
