Demo Broz (Luis Demo (on the right) and Jeffery Demo (on the left))
The Demo Broz (also spelled as Demo Bros) are a pair of sibling construction workers with their own TV show and theme song of the same name, where they show up unannounced at people's homes to tear them down and renovate them without permission. They are the central antagonist of the episode "Lair Necessities", as they use psychic powers given to them by the aliens to lift buildings in order to locate buried treasure.
