Editing Koops

'''Koops''' is a [[Koopa Troopa]] from [[Petalburg]] who is [[Mario]]'s second [[Party member|partner]] in ''[[Paper Mario: The Thousand-Year Door]]''. His left eyelid is half-closed, and he wears a bandage on his nose, a light-blue, short-sleeve jacket with a hoodie, blue shorts, and white shoes. 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's shell in place. He has a girlfriend named [[Koopie Koo]] and a father named [[Koopley]]. His name is a portmanteau of "[[Koopa (species)|Koopa]]" and "oops", an exclamation of clumsiness (Koops being clumsy); it is also a [[wikipedia:Koops|real surname]]. Koops is the only party member to have a defense point without any badges or items, but, like other Koopas, he will fall on his back if hit with a jump attack.

Inside the castle, Koops finds [[Kolorado's father|a skeleton]] by a metal grate. Believing that this dead Koopa is his father, Koops bursts into tears before noticing that the corpse is grasping a letter, which hints at Hooktail's weakness, her deceptive nature, and a farewell to his son, [[Kolorado]]. Embarrassed by the fact that the dead Koopa is not his father after all, Koops is left blushing and scratching his head over the mistake, but then wonders if any of the other skeletons is his father, such as the [[Red Bones]].  

Koops, alongside Mario and Goombella, successfully reach Hooktail at the top of the castle. Once defeated, the near-dead dragon spits up a blue-shelled Koopa with eyebrows and a beard. Recognizing him as his father, [[Koopley]], Koops runs up to reunite with him. After sharing his story of how the dragon tricked him in battle and gobbled him up, keeping him imprisoned for ten years, Koopley reveals that he found the [[Diamond Star]] in Hooktail's stomach and gives it to Mario, "Koops's friend," ending the first chapter of the game.

After this, and with the support of his father, girlfriend, and Mayor Kroop, Koops decides to continue traveling with Mario in his quest to collect the rest of the [[Crystal Stars]], save [[Princess Peach]], and reveal the secrets behind [[The Thousand-Year Door]]. By the end of the game, as the whole party and other characters meet up with Mario and Peach before they take the boat back home to the [[Mushroom Kingdom]], Koops thanks Mario for having helped him find his courage and inner strength, appreciating his new self more and how he has grown closer to his dad (though the remake changes this to him saying that he's become more like his dad). Sometime after this, Goombella would reveal that Koops, now more mature than when he was last seen, plans to run as Petalburg's new mayor, though, noting how he still retains a bit of his old bashful self, she remarks that "Koopie Koo pretty much has him wrapped around her little finger."

As a Koopa Troopa, Koops is the only partner with a defense of 1, though this is negated if he doesn't defend himself with an [[Action Command]] from jump attacks, which will flip him on his back and temporarily immobilize him. Furthermore, he has the lowest health of all partners when upgraded, with 15 Health Points at Super Rank and 25 Health Points at Ultra Rank (sharing the same amount of Health Points as [[Ms. Mowz]]).

In ''[[Super Mario Run]]'', Koops appears as a statue, together with [[Mario]] and [[Goombella]] during an event to celebrate the launch of ''[[Paper Mario: The Thousand-Year Door (Nintendo Switch)|Paper Mario: The Thousand-Year Door]]'' on [[Nintendo Switch]]. His statue is given as a reward after completing all nine event missions from May 23 to June 27, 2024. <ref>https://www.nintendo.com/us/whatsnew/mobilenews-super-mario-run-folds-in-limited-time-missions-celebrating-paper-mario-the-thousand-year-door/</ref>  His statue then becomes available to be placed in the [[Mushroom Kingdom]] through [[Super Mario Run#Kingdom Builder|Kingdom Builder]].  

*In the original game, Koops is inconsistently depicted with either three or four fingers on each hand.<ref>https://www.spriters-resource.com/gamecube/pmttyd/sheet/30431/</ref>{{better source}}

*Despite having a girlfriend, Koops's dialogue in the English version (particularly when running into her once again in the [[Glitz Pit]]) indicates he is attracted to [[Ms. Mowz]] to some degree. Koops even shows a hint of jealousy when she kisses Mario.

*Like Kooper, players are given the option to agree or disagree about letting Koops to join their party, and they both practically beg Mario to bring them along.

*A small glitch can occur with Koops in the overworld when swapping him out with another partner and then back to him, causing him to be slightly smaller than his original size.

*In the section on finding hidden [[Star Piece (Paper Mario series)|Star Piece]] panels in the original game's instruction booklet, the picture depicts Mario [[Spin Jump]]ing with Koops in front of the [[Rogueport Underground]] [[black chest]] which appears closed. This is a continuity error, as Mario does not acquire Koops as a [[partner]] or the Ground Pound ability until after he opens the chest.
