The Xtacles is a spin-off of the Adult Swim show Frisky Dingo and is set within the same universe, with both shows sharing many characters.

The Xtacles themselves are the fighting force behind superhero Awesome-X, who has recently gone missing. They are trained soldiers that wear robotic suits and reside aboard the Xcalibur, a large flying base. The man in charge of them is Jack Taggart, who is joined by A.L.E.X., a sexy computer AI. The Xtacles often receive their mission orders from President Stan, who is usually reluctant to use them.
