Kooper is Mario's second party member in Paper Mario. He is a blue, bold, adventure-loving (and seemingly young) Koopa who dreams of becoming an archaeologist like his childhood hero Kolorado. He is the exact opposite of his successor, Koops, in terms of his personality. However, in the battlefield, the two have very similar abilities. Kooper's name is a pun on the name "Cooper", but with a K for Koopa. Kooper's appearance is similar to that of an ordinary blue Koopa Troopa from Super Mario World (and in later games), except that he wears red arm bands on both hands and a bandana around his neck to distinguish himself from the other Koopa Troopas.
Paper Mario series
Mario and Goombario enter Koopa Village to find that Fuzzies have attacked the village and are stealing all the Koopas' shells. Mario gets the shells back for the Koopas and eventually finds Kooper. He tells Mario that his blue shell had been stolen by a Fuzzy and Mario agrees to get it back. Once Mario gets the shell back for Kooper, he joins the party. In the field, Kooper will retreat into his shell and Mario can shoot him out short distances, allowing him to flip switches, grab items and attack enemies. Kooper has a defense value of 1, meaning he takes one less damage from attacks that happen to damage partners.
When the game ends, Kooper is seen in an expedition with Kolorado in Shiver City. Kooper is told by Parakarry that Peach wants him at the party (which is held at the end of the game). Kooper wants to help Kolorado instead, but Kolorado insists that he go to the party, and so he does.
Paper Mario: The Thousand-Year Door
Although Kooper himself does not appear in Paper Mario: The Thousand-Year Door, early concept artwork exists and unused sprites are found in the game's data. Koops functions very similarly to him, and is even encountered in the first chapter of the game.
