chemistry book, the Coo-Hatch improve Jalil's pocket knife to their quality of metal, giving them a small blade that can cut through anything, the group dubbing it "Excalibur". The Coo-Hatch had no knowledge of guns or explosives prior to the exchange. The Coo-Hatch used the textbook to develop primitive cannons. The Coo-Hatch then aided the Hetwans in almost taking over Mt. Olympus. Later, some of the tribes of the Coo-Hatch team up with the protagonists and develop cannons to use in an assault on the Hetwans (which supposedly takes place after the series end). Their one true desire is to go back to their forges on their home world, which they cannot do without a gateway like Senna or her mother. Though this plot was not built upon later in the series, Senna's mother was sought out to send them back to their world.

They do, however, wield devices similar to long straws (nicknamed "Super-Soakers" by the main characters), out of which they shoot a burning, venomous acid. The Hetwan themselves seem to feel no fear of death or anything. As repeatedly stated by them they exist merely to serve Ka Anor and are absolutely loyal to him. The Hetwan live in a great city that resembles a giant needle sticking out of a pit (referred to by Chris as "Junkie Dreamland"), with an assortment of strange creatures from their home world. The main characters often fight against the Hetwan. Because Ka Anor intends to eventually kill and consume all of Everworld's gods, most of the peoples of Everworld would be considered enemies of the Hetwan, although
