Sturdy, sticky, a cador in the art of camouflage! Gluglu knows how to meander and sneak out of thorny situations. Beware of the wicked, Gluglu is coming! As soon as you need a superhero, Greg sticks to it and becomes Gluglu! At just seven years old and dust, he is the youngest in the band - with six months less than Bibou and eight as Yoyo. But if it is smaller by age and size, Gluglu is the biggest by force! Thanks to his lizard suit, no obstacle is too big to be overcome by him. Nothing can resist him, nothing can stop him except maybe himself, and his own complexes of inferiority in relation to his age, or to the genius of Roméo. His powers: The muscles! The climb! Camouflage!
As European Greg
European Greg is shown to have Sacha and Amaya's attitude on being curious and observing towards things that seem to have interest in school.
Like Yoyo and Bibou, he doesn't even speak in the English language and instead speaks in French.
As European Greg
European Greg is identical to his westernized counterpart. But his sweatshirt lacks the lizard symbol. In the nighttime, his pajamas consist of a pair of light green pants and a shirt featuring a lizard track pattern, but he doesn't have a Gekko symbol. His pajamas also have a white trim.
As Gluglu, he wears a green one-piece costume with frills, a yellow-green belly and a tail to make him more lizard-like. His mask has an opening for his eyes and the lower portion of his face.
Abilities as Gluglu
Gluglu Main Collante: Can climb on walls and other surfaces.
Gluglu Reptilo Camouflage: Can blend into the background, but his eyes will remain visible.
Gluglu Méga Muscles / Gluglu Bloc de Bouclier (officially introduced in "Les Pyjamasques et la graine d'Orticia"): Allows Gluglu to use his muscles and other weapons (such as Bastet's boat oars) for self-defense, and to protect others from harm.
Eat: He can eat smaller enemies such as Mitomites, though, it is not considered to be part of his costume's powers.
