Yoyo (real name: Sacha) is the main protagonist of the Pyjamasques book series. He is a member, one-third of the Pyjamasques. His vehicular method of travel is the Chat-Bolide.
Long before the events of the book series, Sacha met his friends Amaya and Greg in school, and he was originally an average kid.
In "La Légende des Pyjamasques", during the events where Sorceline used her powers to capture the animal totems, Yoyo, alongside Bibou and Gluglu, would receive magical pajamas and powers by one of the three animal totems.
During their first encounter with Sorceline, he and his friends would learn that according to their legend, they had to help rescue the rest of the kids' animal totems.
Eventually, he and the rest of the other Pyjamasques succeeded on freeing the animal totems to restore their legend, and trapped Sorceline and the rest of her Mitomites inside her magical sack from returning to do any harm to them.
Super agile! Ultra fast! He can hear even the slightest noise, even from far away. The intrepid Yoyo never goes back on the adventure - he jumps to the rescue!
Sacha takes enjoyment on being curious and observing towards things that may interest him during school. He can be easily scared at times; this was especially emphasized in "La Légende des Pyjamasques".
As Yoyo, he is shown to be the most courageous member of Les Pyjamasques. As emphasized in "Les Pyjamasques et l'opération zéro" and "Les Pyjamasques et le cadeau de Sorceline", he is also the most intellectual member as he is shown to give out morals and lessons to others who are facing problems and is efficient to think of any ideas to stop villains (without using their powers).
It is emphasized in "Les Pyjamasques et le croque-chaussettes" that Yoyo will tell lies and forgets about the Night of the Black Moon.
He doesn't even speak in the English language and instead speaks in French.
Motive & Abilities
In most of his appearances, Yoyo and the rest of the Pyjamasques will often encounter and fight various nighttime villains that are mythology/folklore oriented.
In addition, they would help friends in need who are also mythology/folklore oriented.
- Acrobatics: His primary ability; he is very agile and can perform back flips, cartwheels and high jumps at ease.
- Yoyo Acrobasaut: Can jump really high.
- Yoyo Rapido: Can run really fast at lightning speed.
- Yoyo Magiques Rayures: Can shoot blue magical stripes that wrap around his opponents and tie them up.
- Hand-to-Hand Combat: He is efficient at using his wits and physical strength during a fight, such as catching Sablotin's metal moons at the fastest reaction time, or throwing one of his books to block Magistère la sorcière's visibility vision.
- Head Balancing: Yoyo, along with Bibou and Gluglu, are able to balance with each other on their heads.
Sacha has a blue teal shirt and darker tone pants, and his T-shirt is blue. He also has brown eyes in color and wears white sneakers with blue shoelaces, but was previously to have blue eyes and red sneakers before the events of "Les Pyjamasques et la momie d’Apophis, Tome I".
During the night, his pajamas consist of a traditional stripey white and blue shirt and pants. His feet also appears to be bare.
As Yoyo, he has turquoise eyes instead of brown eyes. He wears a turquoise one-piece suit resembling a cat with ears, a tail, a white underbelly and many blue stripes. The costume leaves an opening for the lower portion of his face.
In his appearances before "Les Pyjamasques et l'opération zéro", Yoyo originally had white paws and feet, a different arrangement of stripes on his costume, and his white underbelly is smaller in size.
In his solo appearance in the pilot episode of the PJ Masks, he is identical to his early appearances in the book series. However, he lacks his white paws and feet, and has blue cat ears.
