13

13 is the main protagonist of the Thirteen-Tulpaiverse, and is the mascot of the Secret Lab.

13 is slick, secretive, but overall fun to hang out with. He's very smart and witty, and he knows how to defeat enemies rather quickly.

13 is a very violent cat. He has a fascination with weapons, like bombs and explosives. In fact, he is a terrorist himself!

13 is a demon from Hell, who came onto Earth since he was sick and tired of the heat down there. He met Jumbah and they eventually got into a gay relationship. (watch Jumbah from the Thirteeniverse channel to understand.)
