Romeo is one of the two main antagonists from the Disney Junior show PJ Masks. He is one of the nighttime villains. Driving his mobile laboratory throughout the city, this crazed scientist and inventor is bent on nothing less than world domination.
Not much is known about Romeo's day-to-day life, other than that he knows the true identities of the PJ Masks. He also plays as the true antagonist of the show. A marvel of mechanical mischief, Romeo is so wrapped up in his own genius as he attempts to launch his latest invention to capture the PJ Masks and take over the world! With his mobile laboratory and many a gadget, PJ Masks have their work cut out but with teamwork and cooperation, Romeo's genius is no match for the PJ Masks! In Season 2, after Armadillain was kicked off the team by the PJ Masks, he sides with Romeo and with the help of Romeo's inventions, they could be able to defeat Armadillain's former friends "PJ Masks" and then take over the world.
