PJ Masks - Meet Romeo!

PJ Masks - Meet Romeo!

Romeo is an evil young mad scientist and a child prodigy who plans on world domination with robots, inventions or anything to make the world love him. He is considered the main villain of the series.

Official website description

Romeo: 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!

Motive & abilities


Romeo is the only villain in the series so far that has a clear ultimate motive: to take over the world. With the PJ Masks easily being the greatest hindrances for Romeo’s goal of conquest coming into fruition, he simultaneously dedicates his time and efforts in trying to derail their continued heroics as much as conceiving and enacting his own schemes for world domination. He has built over a dozen different technologically (and some logically impossible) advanced inventions such as the Pogo Dozer, Electromagnet and the Anti-Gravity Machine to assist him with his plan but has always failed.


Romeo doesn't possess the acrobatic and physical agility of Night Ninja and his Ninjalinos, nor the assistance of moths like Luna Girl, but he uses the power of knowledge and invention to help him take over the world.


Romeo is extremely intelligent for his age, but sadly, like many about as young as he is, Romeo fails to see the sagely distinction between knowledge and wisdom, consistently confusing either for both. He isn't very physically combative, nor is he particularly arrogant about his intellect, but is very bent and keen on taking over the world. He has an intense dislike for the PJ Masks, but isn't extremely violent with them. He usually accepts his fate and flees when he knows he is defeated.

Romeo has a very respectful Robot that performs tasks for him and brings him from place to place. Similar to how Luna Girl is with her moths, he tends to mistreat his robot and acts stubborn towards his warnings about the PJ Masks. It could be possible that Robot is his only friend.

Physical appearance

Romeo wears a moderately-tight white lab coat with a bag strapped to his back. Along with his coat, he wears teal covered gloves, gray boots, gray pants, and black goggles with a short and thin wire antenna standing outside from the edge of the left lens frame. Romeo has fair skin, blue eyes and a black spiky hairdo with a white streak just over his left eye.
