Gekko may be the youngest member of the team but he’s a strong and sticky master of camouflage! He’s ready to rush into danger and save the day with his super Gekko muscles. Always ready for action Gekko can scale walls and with his Gekko-mobile so can all the PJ Masks! It can even travel underwater. Watch out baddies, here comes the mighty Gekko!
Greg can sometimes be competitive when it comes to playing games, but he isn't very good at speaking to his class (as evidenced in "Speak UP, Gekko!"). When he isn't Gekko, he isn't as strong and that sometimes causes him to doubt himself. This is usually remedied by Connor and Amaya's encouragement. He's also nice, friendly, helpful, somewhat shy, fun, playful and brave.
On occasion, Gekko pretends to be Kick McGee along with Catboy playing as Master Fang during missions. He sometimes displays insecurity, such as in "Gekko's Super Gekko Sense" when he made up a new power due to thinking that the powers he actually had would now help win the game. He can be easily distracted (which was emphasized in "Slowpoke Gekko"). Like his fellow teammates, childlike immaturity tends to overtake his mindset on the mission leading to issues (such as rejecting Owlette's desire to play along as Flossy Flash with them in "Catboy and Gekko's Robot Rampage"), but this is always realized and corrected leading to the mission being done properly, and the villain's plans foiled.
Greg has pale skin, green eyes and a blonde parted hairstyle. During the daytime, Greg wears a green long-sleeved shirt with a lizard symbol and brown drawstrings and brown beige pants. In the nighttime, his pajamas consist of a pair of light green pants and a shirt featuring a lizard track pattern and his signature Gekko symbol. His pajamas also have a white trim.
As Gekko, he is identical to his mainstream counterpart, but has a few differences. Examples include the addition of scales at his costume, a lizard symbol at his chest rather than an actual lizard belly that his book counterpart has, and he has more dark green padding to his shoulders, hands and feet.
Gekko is often portrayed to have a more stern and edgy expression than his book counterpart, as well as having a more-visible fighting pose at times.
