Monsters are popping up all over, wreaking wild havoc on Earth! Captain Woof, a dog from another dimension, is here to find out what's been weakening the walls between parallel universes and letting these creatures through. Helping him are Captain Mysterioso, a teen reassembled by aliens to be invulnerable and shoot destructo-rays; Captain Bummer, a woman with the power to push anyone to suicide; and Captain Smooch, a playboy that one kiss can turn into a raging beast. Throw in Captain Megahertz, a man who can travel along any electrical frequency, and you've got the Captainz! A rollicking love letter to superhero comics.
