It Must Be Mine
"I said to the Red Bull, 'I must have them! I must have all of them, all there are!"There is a valuable thing out there. It's one-of-a-kind, which makes it the greatest prize ever. That means someone wants it, just for that reason, by any means. Note it's not the artifact hypnotically seducing the person into wanting it. The person is just that selfish or greedy. Nor is it something earned; it's outright taken. It also doesn't count if someone steals it for the thrill of the theft, or to just show how good a thief he/she is. Either the thief has to want it, or he/she is stealing it for someone who does. Note that this rarely ends well, no matter whether the story is idealistic or cynical. That person stole something they shouldn't keep. In idealistic stories, it's too important to lock away. In cynical stories, it's too dangerous to try to lock away.
— King Haggard, The Last Unicorn
Examples:Anime and Manga
- That Gelarden or Lawrence III, depending on the language, in Pokémon 2000 who captured the Legendary Birds.
- Lupin III doesn't count for this trope. He never wants it for the rarity, and has often taken something just to make sure someone else doesn't have it. On the other hand, Fujiko is also the cause of many of their capers. To the point where Jigen will try to quit the job once he hears it was her idea.
- The actions of Fiamma of the Right, the former Man Behind the Man of the Roman Catholic and Russian Orthodox Churches in A Certain Magical Index, are guided solely by his obsession with possessing Touma's Imagine Breaker and becoming more powerful than God himself.
- Professir Machinegal in Moldiver has this as his main motivation for being a supervillain. He already is wealthy, respected and famous, but there are technological artifacts he can only get by stealing, and he doesn't think anyone but him are worthy of them anyway.
- In Shakugan no Shana, the villain Sorath was obsessed with obtaining Shana's Flaming Sword Nietono no Shana. When he manages to steal it, he throws away his own Cool Sword Blutsauger.
- There's also a Marvel Comics character named The Collector, who collected unique specimens from across the universe.
- The original motivation of the Batman villain the Cavalier was to obtain unique pieces that he was unable to purchase for his collection.
- Larfleeze wants everything, but especially rare things, like Lantern rings he's never seen before.
- Most of the characters in The Maltese Falcon will go to any lengths to obtain the fabled bird.
- There is a story where a princess (or maybe duchess) hears someone in her land has a talking cat. She wants it for herself, so she throws the owner in her dungeon. One scene has her riding in her carriage, carrying the cat in her hand muff, and the cat escapes by biting her hand.
- All of the unicorns, in The Last Unicorn, collected by King Haggard.
Haggard: They are MINE! They belong to ME! The Red Bull gathered them one-by-one and I bade him drive each one into the sea! I like to watch them. They fill me with joy. The first time I felt it, I thought I was going to die. I said to the Red Bull, 'I must have them! I must have all of them, all there are! For nothing makes me happy but their shining, and their grace.' So, the Red Bull caught them. Each time I see the unicorns — MY unicorns — it is like that morning in the woods, and I feel young, in spite of myself!
- In Robert Asprin's fantasy novel Myth Directions, Tanda the Trollop assassin ropes protagonist Skeeve into her attempt to find a truly one-of-a-kind item to give to Aahz (a scaly green Pervect) as a birthday present. She ultimately settles on a ghastly frog-scuplture trophy that has no value except as the prize for a heated sports competition between rival cities. Their robbery attempt goes horribly wrong, and things only spiral further out of control from there.
- To add to it, Skeeve tries to keep Aahz from finding out about any of this because he knows the lecture he'll get for having done something like this. When Aahz does find out and asks incredulously "This ugly statue is what's behind all this?", a frustrated Skeeve responds "Yeah, because we wanted to give it to you. Happy birthday." After a stunned minute, Aahz decides It Must Be Mine and the group alters their escape plan to include the theft of the trophy.

- Simon R. Green's Nightside books feature the Collector, who is reclusive, petulant and somewhat childish in his single-minded devotion to things that - in his opinion - only he can truly appreciate.
- The Star Trek: The Next Generation episode "The Most Toys". The thing that was stolen was Lieutenant Commander Data. It probably wasn't one of Kivas Fajo's better business plans...

- In City of Death, a key plot-point involves the theft of the Mona Lisa to be sold (along with six identical paintings) to finance Count Scarlioni's temporal experiments. Inspector Duggan observed to the Doctor at one point, "There are at least seven people in my address book who'd pay millions for that picture, for their own private collections. It would be an expensive gloat, but they'd do it."
- At least one Mission: Impossible episode had a millionaire who had a national treasure that the original nation wanted back, and it was important they get it for reasons of international politics. The current owner was not cooperative.
- Comes up in Dad's Army of all places where Mainwaring is trying to buy some oranges at a charity auction from the warden, who predictably is doing everything in his power to stop him getting them. Eventually Wilson tells Pike to buy an orange for Mainwaring, but neglects to tell the captain, resulting in Mainwaring entering a furious bidding war against himself. He eventually ends up paying ten shillings for it (when the first one sold for a couple of pence).
- Kamen Rider Diend of Kamen Rider Decade has a 'treasure' in each episode that he is seeking. He alone knows what makes something a 'treasure,' and he only wants it because it is one, and rarely for what it actually does (some of 'em are important to the plot.)
- Happens often with the marks in Hustle. Examples include a rare banknote in "The Lesson" (or so it seems), a case of rare wine in "Getting Even", and a Faberge Egg (one of a matched pair) in "Eat Yourself Slender".
- Joey Ryan's explanation for showing up in Championship Wrestling From Hollywood with the organization's television title belt, even though he never won it. As the biggest television star on the card, why shouldn't he have the belt?

Lawless: You removed it from its original packaging!Collector: No! It's no longer a collectible!
- Mr. Krabs had just sold a cap to SpongeBob SquarePants when another person showed up saying it was a rare cap and offering way more than what Spongebob paid. Krabs spent most of the episode trying to recover it and, by the time he did get it back, several others appeared, making it not so valuable anymore.
