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).
He doesn't even speak in the English language and instead speaks in French.
Sacha has a blue teal shirt and pants is darker in tone and his T-shirt is blue. And he wears white sneakers with blue shoelaces like Greg. He also has brown eyes in color, but was previously to have blue eyes 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.
As Yoyo, he has turquoise eyes instead of brown eyes. He wears a turquoise one-piece suit resembling a cat with ears, a tail, and many blue stripes. The costume leaves an opening for the lower portion of his face.
