Marsupilami is a very strange yellow animal with black spots (although there does exist an entirely black version, it’s very rare).
His general appearance is that of a Marsupial (which inspired his name along with the words Pilou-Pilou and « ami » friend in french.)
However, his most surprising peculiarity is his tail. In fact, he has a long tail, very robust, strong and very agile. Of course, he uses it to grab objects, but it also has other purposes : if he rolls the end of it into a ball, it becomes a very effective club. If he rolls it into a spiral, then it becomes a large spring coil which he uses to do long bounds. It even serves as a fishing rod for piranhas.

In fact, Marsupilami lives in the natural wilderness of the jungle, the Palombian jungle (name inspired by the french words « colombe » dove and          « palombe » woodpigeon). His basic diet consists of fruits and piranhas.
He lives in a nest, suspended in a tree, which has the form of a walnut opened into two halves, and in which an ingenious device permits rapid closing in case of danger.
With Spirou and Fantasio, he lives adventures outside of his native jungle, and here we learn the existance of a certain number of other characteristics. He is, among others, a ventriloquist, amphibious and an ant eater... Back in his jungle, these characteristics fade. Marsupilami was created in « Spirou et les héritiers ».

He accompanies Spirou and Fantasio in their adventures. An entire Spirou album is built around him : « Le nid des Marsupilamis ». As well, he shares several other adventures independently of Spirou and Fantasio, such as with little Noël.
When Franquin stops Spirou and Fantasio, the personage of Marsupilami remains his property. Marsupilami returns to live in his native jungle of Palombie. Franquin makes him live two short adventures in the company of Bring M. Backalive, a wild animal hunter.
