Nimona is a young shapeshifter, the sidekick to the Sir Trabuco Negroni, a villain with a vendetta--he wants to prove that Sir Ambrosio Pieldorada and his allies at the Instituto de Justicia y Heroísmo aren't the heroes they say they are. There will be, in the beginning, small acts of mischief, which will escalate into explosions, with lots of science and sharks in between.
