There’re a couple of characters I’m probably missing. And there are going to be a lot more characters in the future.

Skipper, Private, Rico, Kowalski, Marlene, Julian, Mort, Maurice, Alice, Burt, Roy, Rhonda, Mason, Phil, Lu-Lu, Hans, Blowhole, Rat King and rats, Savio, Clemson, Doris, (does she count?) the Koala, (I forget his name) Joey, the sheep, the chamelians, Blowhole's crabs, Hunter, Bada and Bing, Antonio, Fred, Manfeedi and Johnson.

I think that's all of them.

I'm slowly piecing together an alphabetized list of all the characters that have ever appeared on The Penguins of Madagascar. But given the number of episodes, this project could take me a while.
