Yoyo (real name: Connor/Sacha), also known as "Catboy" (in US and other international regions), is the main protagonist of PJ Masks. He is the leader, one third of the PJ Masks and he is the descendant of Yoyo from an alternate universe. His vehicular method of travel is the Cat-Car.
Catboy is the leader of the trio and the oldest too. Incredibly fast, amazingly agile, he can hear the quietest sounds across unbelievable distances! But he's also afraid of water! Still, when adventure beckons, “The amazing Catboy leaps to the rescue!” With these skills Catboy can outrun anyone and gives Night Ninja a challenge with his amazing leaps and acrobatic moves! His vehicle the Cat-Car gets the heroes from A to B in lightning speed and even shoots moth balls should there be anything in the way!
Connor takes great enjoyment in associating with Greg and Amaya. He can be a bit clumsy at times; this was especially emphasized in "Clumsy Catboy". He's also nice, smart, caring, friendly, helpful, and funny. In "Catboy's Great Gig", it is shown that he sometimes has intense stage fright, similar to how Greg becomes nervous when he's presenting to the class.
As Catboy, Connor leads the PJ Masks through the steps of defeating villains such as Romeo, Luna Girl & Night Ninja. He prefers to have his own way, but still respects Owlette and Gekko when they ring in with their opinions. On many occasions, like his fellow members, childlike immaturity tends to overtake his mindset on the mission leading to issues (such as getting frustrated in "Catboy and Master Fang's Sword" and letting leadership go to his head in "Catboy Takes Control"), but this is always realized and corrected leading to the mission being done properly, and the villain's plans foiled. Despite being the leader of the team, each member still has as much priority.
As Kitten Boy
When he got zapped by the Baby Beam and turned into Kitten Boy in "Terrible Two-Some", he can be quite curious, playful, and cute, but sometimes, he can be bratty, demanding, and more emotional. He can sometimes act like a real cat and he can actually drink milk from a bowl like one, too. He also likes to chase butterflies, play with fur balls, and he can even walk, climb, sit, pounce, and run like a cat.
As Night Panther
When Catboy got zapped by the Opposite Ray and turned into Night Panther (also known as Tigre Noir) in "Gekko and the Opposite Ray", he is evil and hostile, as he and Dark Owl are super enemies with Gekko. However, he always argues with Dark Owl a lot, and also competitive, since he and Dark Owl have tried to win against each other when trying to defeat Gekko.
Connor is identical to Sacha, except that his skin is darker in tone, his eyes are blue in color instead of brown, has a blue teal shirt and pants that is lighter in tone, and his T-shirt is white instead of light blue. He also wears red sneakers with lime green shoelaces instead of Sacha's white European sneakers.
During the nighttime, his pajamas consist of a blue shirt with his signature cat symbol in the middle. His shirt and pants carry the same striped design. He also wears blue slippers.
As Catboy, he is near identical to Yoyo, but Catboy's different color is a darker tone of blue, has slightly shorter ears and tail, and his stripes are a lighter tone of blue and has a pattern that resembles a lightning bolt. Also, he has a signature cat symbol at his chest instead of having a white cat belly that Yoyo would usually have.
Catboy is often portrayed to have a more stern and edgy expression than Yoyo, as well as having a more-visible fighting pose at times.
As Night Panther
As Night Panther (also known as Tigre Noir), his appearance is identical to that of his superhero identity, but his different color is black with white stripes and dark gray eyes.
