The Collector is a Creator Curator who is the main antagonist in LittleBigPlanet.
The Collector is a small, menacing, envious character who is determined to steal the other Creator Curators and their friends and become the ruler of the whole of LittleBigPlanet. It can be assumed he used to be a peaceful Curator for such a thing not to have happened before, but his loneliness and envy for the other Curator's creations must have led him to seek dominance over the planet and create dangerous animals and a stronghold. For the majority of the game, The Collector is egotistical and treats everyone else as if they are inferior to him. He seems confident in his machines and cares not for the well-being of others. He can be seen in each of the other Curator's locations as well as his own; he captures some of the characters whilst the player is traversing their worlds, so that said player can get an early glimpse of the main antagonist.
He first appears early in the game disguised as Dumpty in Skate to Victory and peeks in through a window in the haunted castle. He later appears in The Meerkat Kingdom disguised as a Meerkat in the VIP room at the nightclub. However, his most obvious appearance is when he comes to swipe Don Lu's Dog in The Darkness in his pod, which he uses for his captures from that point onwards. He appears once again in Boom Town, where he abducts Frida and Don Lu during their honeymoon. He then appears in Subway, carrying Ze Dude, and then again at the start of Endurance Dojo, carrying away a lot of sushi and a doll. His final appearance before The Wilderness is in The Dancer's Court where he kidnaps one of the dancers.
He kidnaps many characters throughout the game, and eventually has all the other Creator Curators and the majority of the other non-player characters captured and locked in The Collector's Lair. The player goes to rescue them and frees them all before taking on The Collector in the level of the same name. The Collector tries to defeat the Sackperson with his powerful robotic devices but in the end is cornered, his robotic armour damaged beyond repair. There he openly confesses that he only stole things because he was jealous that he didn't have any friends to share his creations with. The King suggests that the rest of the LittleBigPlanet community can be his friends and he seems to agree, ultimately forgiven for his criminal ways.
