"You win this time, PJ Pests, but you haven't seen the last of Romeo!"
~ Romeo

Romeo is the main antagonist of the animated show PJ Masks ahead of Luna GirlNight Ninja and the Wolfy Kids.

He is voiced by both Alex and Carter Thorne, who also voiced Zuma in Paw Patrol.


Romeo wears a white lab coat with a satchel. Along with his coat, he wears teal gloves, gray boots, gray pants, and black goggles with a short and thin 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.


Romeo is extremely intelligent for his age, but 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, but is very bent and keen on taking over the world. He has an intense dislike for the PJ Masks, but is not extremely violent with them. He usually knows when he is defeated.

He does not seem to care for anybody other than himself and his robot minions, Robot and Robbette, the latter two he occasionally insults. Despite this he has shown a nice side to them especially Robot, shown in Catboy and Gekko's Robot Rampage and Nobody's Sidekick.

He has strong rivialry with Luna Girl and to a lesser extent Night Ninja but he occassionally teams up with them as seen in "Catboy and the Shrinker", "Wacky Floats", "PJ Masks vs Bad Guys United", and "PJ Comet".

In "PJ Masks Save Christmas" he is shown to have a kinder side and chooses to be good on the holidays from now on.



Romeo's backstory is unknown, other than he has known the Pj Masks for a while and knows thier secret indentiteis.
