Skipper- "is the leader of the penguins, who forms tactics and gives orders. He is usually cool-headed, calculating with exaggerated bravado. He usually views everything as some type of covert military operation. He is shown to have a secret fear of needles. He can't step foot in Denmark for unknown reasons. Sometimes in the series, we see Skipper have a coffee cup with a fish in it. He has a nemesis named Dr. Blowhole. "

Kowalski-"acts as the group strategist and gadgeteer. Kowalski is highly intelligent, but tends to over-analyze situations. "

Private- "is the emotionally sensitive rookie of the group, who has a knack for cracking codes. Though less experienced than the other penguins, he is shown to be the most down-to-earth. He has a British accent and is sometimes prone to accidents. "

Rico- "is the team's weapons and explosives specialist, who mainly communicates through grunts and squeals. Rico swallows useful tools, such as dynamite, and regurgitates them when needed. He has a scar on his left cheek, and he is also shown in love with a Barbie-like doll."

Marlene- "is a female otter who was transferred to the Central Park Zoo from an aquarium in California. She is close friends with Skipper and sometimes tags along on his missions, but she is often a neutral character who does not take sides between the penguins and the lemurs. By being a levelheaded, feminine voice of reason, she is a counterpoint to Skipper's masculine, covert ops character."

Julien- "is a ring-tailed lemur, the self-proclaimed lemur king and the shows main antagonist. Julien is a comically conceited character who has little regard for his "subjects", Maurice and Mort. He has a tendency to use malapropisms and misinterpret figures of speech."

Maurice-"is an aye-aye who is one of Julien's subjects. While Maurice accepts his life as a servant, he often shows disdain towards Julien and his hare-brained ideas. He has a crush on the baboon named Darla who stole Julian's groove."

Mort- "is an accident-prone mouse lemur. Unlike Maurice, Mort is fiercely devoted to Julien, even displaying an obsession with the lemur king's feet. However, Julien treats him with contempt."
