Koops

"OH, PLEASE TAKE ME WITH YOU TO FIGHT HOOKTAIL! PLEASE! I'M BEGGING YOU!"

- Koops

Koops is a Koopa Troopa from Petalburg, and the second partner to join Mario's party in the game Paper Mario: The Thousand-Year Door. Very much like Kooper from the original Paper Mario, Koops can retreat into his shell and use it as a weapon against foes, and Mario can also launch him at switches or distant objects to hit them or retrieve them. However, he differs from Kooper in that Mario can hold Koops' shell in place.

Paper Mario: The Thousand-Year Door
Koops first meets Mario in Petalburg. He doesn't say much, but before Mario leaves to another part of town, he stops him, then his shyness overcomes him and he goes back. When Mario goes off to Hooktail Castle, he stops him again and is firm that he wants to join Mario's party in order to avenge his 'dead' father, but not before Koopie Koo finds out. She begs him not to go, but he says he has to be a strong Koopa for her. She gets mad, withdraws into her shell, and fires herself at Mario and Koops.

Inside the castle, Koops finds a skeleton that he believes is his father's. Reading the note the corpse was grasping reveals it was actually Kolorado's father. Koops is slightly embarrassed, but then wonders if any of the other skeletons is his father.

When Mario and Koops first meet up with Hooktail, the dragon remarks that they look similar to one that passed by here recently. The battle then starts. Once the fight is finished, a near-dead Hooktail spits up Koopley, who was living in Hooktail's stomach for ten years. After a touching reunion, Koopley reveals he found the Diamond Star in Hooktail's stomach, and allows Mario to take it.

After assisting Mario in his quest to collect the rest of the Crystal Stars and save Princess Peach, Koops returns to Petalburg where he makes plans to marry Koopie Koo and run for mayor.

Goombella's Tattle
"That's Koops, from Petalburg. He's got confidence issues... He's a... cringer, y'know? But he's definitely got a serious interest in Hooktail... I wonder why?"

"That's Koops, from Petalburg. He's been waiting here, hoping to join you. He's a bit green, but braver than i thought... I'll have to rethink my first impression. I mean, he seems totally earnest, know what I mean? We should take him along."

Super Paper Mario
In Super Paper Mario, Koops appears as a Catch Card won by winning the Duel of 100 in the Sammer's Kingdom. Koops could also be seen very briefly during the intro, where he and all the other partners from the previous Paper Mario titles could be seen in a photograph at Mario's House.

Catch Card
Card Type: Rare Card Description: It's Koops from the last Paper Mario adventure. Kicking some shell never felt so good. How to Obtain the Card: The Duel of 100 in Sammer's Kingdom needs to be completed in order to obtain all Paper Mario: The Thousand-Year Door partner cards from King Sammer.

 * Koops is the second character in the Paper Mario series (with Lakilester being the first) to join Mario's party, so he could be tougher for his girlfriend.
