Thunderverse is a universe on Nickelodeon based on the original series, The Thundermans, followed by the movie, The Thundermans Return and the spin-off series, The Thundermans: Undercover.
In this universe, superpowers exist because of the Power Plant resulting in superheroes and supervillains existing. The Thundermans use "supes" and "non-supes" to distinguish between people with superpowers and those without.
Regular humans are aware of the existence of superheroes and supervillains but are not aware of most of their identities due to being kept a secret. Metroburg is the main location of superheroes and supervillains and where they operate, including where the Hero League and Villain League headquarters are set up.
