Fireball is a series of CGI anime shorts created by Jinni's Animation Studios in conjunction with Disney. The designer is Hitoshi Fukuchi. It is animated entirely in 3D with no cel-shading of any sort, as would be typical for the medium.

The show takes place in the distant future of the 49th millennium, and revolves around the happenings inside a giant manor inhabited by two robots; the gynoid duchess Drossel von Flügel and her massive cyclopian arachnoid servant, Gedächtnis. The episodes are usually nonsensical in nature, normally showing the two characters making idle conversation in the midst of a war with humanity. A third character, a monkey-robot named "Schadenfreude", joins them later.

Makoto, Adi, and Chloe attend a special training school where they train to become the heroes of the next generation. Unfortunately for them they are actually science experiments for Hydra. When Adi and Chloe get captured by Hydra for learning the truth, Makoto seeks out the one group he believes could help them- The Avengers. After rescuing the kids The Avengers decide to take them in and train them to be the heroes of the future.
