The Ultimate Vampire Resource and Directory

The series centred around three young men (apparently in their late teens): Drak (called Drak Jr. in the opening segment, but almost never in the series; voiced by Jerry Dexter), Frankie and Howler (both voiced by William Callaway), descendants of Dracula, Frankenstein's monster and a werewolf. To atone for their ancestors' wrongdoings, the three, united as the Drak Pack, became superheroes.

They appeared initially as normal humans, but when they put their hands together and shouted "Whack-o!" (called the Drak Whack) they would transform into a vampire, a monster and a werewolf, respectively. Drak's powers included flight, telekinesis, and the ability to change shape. Unlike most cartoon vampires, Drak was able to assume a variety of forms, although he did favor the customary bat. Frankie had superhuman strength and could release electrical charges. Howler had an ultrasonic howl and super-breath, apparently an homage to the Big Bad Wolf of The Three Little Pigs. Oddly, even in human form, they called each other by the same names, calling into question why they had secret identities.
