korps supervillain enrichment chambers.
places where supervillains can go to do supervillainous activities without the harm of doing them to people. like poisoning the water supply(with horny transformation formulas), fighting a superhero(only sometimes proton), and explaining their scheme to a trapped hero(less likely to be proton than the fighting part)
Proton, rigged up to a faux death trap because Sakura asked him to cover fo their other dummy superhero: "The things I do for love."
