Romeo is the main antagonist of the PJ Masks television series. He 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; and is the descendant of Roméo Mécano from an alternate universe.

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, his flying factory and many gadgets, PJ Masks have their work cut out but with teamwork and cooperation, Romeo's genius is no match for the PJ Masks!


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 and has an ego to prove that he's the greatest inventor. 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.

In "The PJ Masks Save Christmas", Romeo is shown to have a kinder personality. After opening up Robot's present to him, he becomes touched by the Christmas spirit of giving and decides to help the PJ Masks and Santa Claus return the Christmas presents and decorations to the town. Once that is finished, he proclaims that he will be good from now on, but only during the holiday season since he is still a villain after all.

As Captain Smarty Pants

When Romeo got zapped by the Opposite Ray and turned into Captain Smarty Pants in "Gekko and the Opposite Ray", he is friendly and nice towards Gekko. He's also considered helpful since he helped Gekko while he was trying to defeat Night Panther and Dark Owl.

Motives & abilities


Romeo has one main motive: world domination. 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. Unlike his book counterparts, he has built modern futuristic-themed (and not as vintage-themed) inventions that are somewhat more advanced (and some logically impossible) and harmless such as the Pogo Dozer, Electromagnet and the Anti-Gravity Machine to assist him with his plan but has always failed.

Despite his motives on world domination, there are some cases where he only wanted to take over the city and turn it into his private town instead (as seen in "Gekko and the Mayhem at the Museum").


  • High Intelligence: 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.

Physical appearance

Romeo is identical to Roméo Mécano, but the only difference is that his scientist coat's buttons are square and black in color, wears darker gray pants and boots instead of white pants and normal shoes.

Another difference is his goggles looks more detailed with a short and thin wire antenna standing outside from the edge of the left lens frame. His hair is black with a white streak instead of being blue, and his hairline is smooth instead of being spiky.
