Real Superheroes Zazu encounters: Uum Kalthoum, Stephen Hawking, Emma Lazarus, Jacques Cousteau, Rachel Carson, Baruch Spinoza, Nelson and Winnie Mandela, Colin Kaepernick, ibn Sina, Martin Luther King Jr.

Over the course of their travels across the Caribbean, India, North Africa, and the Middle East, the three main characters, Zazu, a malamute husky, and a humpback whale, meet many superheroes, such as Maimonides, Rashbi, Queen Zubadya, Rabindranath Tagore, Joha the Sephardic trickster, Gandhi, Sol Hachuel, Harriet Tubman, Doña Gracia Nasi, and Noor Inayat Khan. Together they learn about how they can challenge 21st century villains like Nestlé, Merck, Exxon, and Monsanto—Big Pharma, Big Oil, and Agribusiness giants that stalk the planet. The characters learn about all living things that co-exist as a kind of social permaculture–all interconnected systems of mutual support.

Zazu also encounters historical figures such as Sol Hachuel, Harriet Tubman, Doña Gracia Nasi, and Noor Inayat Khan.
