“I've been admiring Professor Kolorado ever since I was in my egg! Nothing would make me happier than traveling the world, solving mysteries like he does! So... Do you think.. Could I... Please take me with you, Mario! I'll help! C'mon, lemme go!”
Kooper, Paper Mario

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.

Kooper, Paper Mario

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.

Kooper receives three letters in the Toad Town Post Office throughout the game: one from Kolorado's wife, one from Koover and one from his fan.

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.

Duplighosts and Lee can transform into Kooper along with Mario's other partners, where his name appears as "Kooper???"

Super Paper Mario[edit]

Kooper appears in Super Paper Mario as a Catch Card found on the thirtieth floor of the Flopside Pit of 100 Trials and is pictured in the Mario Bros.' House. Although he does not make a physical appearance, his sprites are still present in the game's data.

Super Mario-kun[edit]

Kooper, along with Goombario, is seen with Mario in the Paper Mario arc in Super Mario-kun. In volume 28's Super Wario-Kun, he is pushed away along with Mario and Goombario by Wario's foot.

Mario Golf: Toadstool Tour[edit]

In Mario Golf: Toadstool Tour, Kooper's name sometimes appears on the scoreboard in Tournament mode.

Super Smash Bros. Brawl[edit]

In Super Smash Bros. Brawl, he is a Sticker that raises arm attack power of a player by ten.

Unused appearances[edit]

Paper Mario: The Thousand-Year Door[edit]

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.

  • Player's Guide: The happy-go-lucky Koopa from Koopa Village will join your party after you retrieve his shell. When you have him by your side, you can use his shell to pick up items or hit objects that are out of your reach. His shell flies away then comes back like a boomerang.[2]

Unused sprite of Kooper in Paper Mario: The Thousand-Year DoorAn image of Kooper, unused in Super Paper Mario.
Kooper's unused images, from Paper Mario: The Thousand-Year Door and Super Paper Mario, respectively.
  • Although one of Kooper's artworks depicts him having an "X"-shaped arrangement of bandages on his cheek, no in-game sprites have shown him as such, not even those of Paper Mario: The Thousand-Year Door or Super Paper Mario. The bandage is also not present in other artwork. The art is likely intended to accompany the one of Mario with a bandage, both after a battle.
  • In the Japanese version, Kooper talks like a kid with a considerable overactive attitude using words like「オレッチ」(orecchi, me) and finishing his dialogues with「っス」(~su), a very polite and infant way to say「です」(desu, to be).
  • In the Simplified Chinese version localized by iQue, Kooper implies that he has a wife during his first encounter with Mario. This is likely due to the translators misreading "life" as "wife".[4]
