King Olly

King Olly, also known by his title Origami King (or origami king) or simply Olly, is the ruler of the Origami Kingdom, the leader of the Folded Soldiers, and the titular main antagonist of Paper Mario: The Origami King. He is the elder brother of Olivia, and he turned many paper characters including Princess Peach into origami figures and made them fall under his control. His traits include his folded crown and hair, his purple robe, and his spiky limbs. He is sometimes seen with a dark tan, striped patch of hair, purple skin, and glowing purple eyes. He can also fold himself into a yellow Shy Guy, which he uses as a disguise. His endgame is to wipe all the Toads out of existence using the Thousand Cranes technique.

Background
King Olly was created by the green Toad Origami Craftsman, to fit in an origami castle created for the Toads' origami festival. The Origami Craftsmen wrote a message on King Olly wishing he would grow into a great king, but Olly misinterpreted it as a "careless scrawl" and became embittered. King Olly then folded Olivia, and began to view all Toads with contempt due to them all being the same to him, which eventually grew into genocidal hatred of them. This became the basis for his grudge against entities made of flat paper instead of origami.

Paper Mario: The Origami King
While disguised as a yellow Shy Guy, King Olly created the Folded Soldiers out of flat paper and stole Princess Peach's castle using five paper streamers; planning to turn it into a replica of the castle made for the origami festival. When Mario, Olivia and Bowser all confront him, they all get thrown out the Castle by Olly's paper streamers.

He reappears in Sweetpaper Valley where he crushes Olivia beneath a boulder and blocks the entrance to a cave needed to get to the yellow streamer.

When confronted in Peach's Castle, he transforms the castle into Origami Castle and sticks Princess Peach on the wall in his throne room. He attempts to kill Olivia with a Stapler, which leaves her somewhat traumatized until Bowser and Mario both reassure her. He then battles with Mario, Olivia and Bowser by using his shapeshifting powers by turning into a Vellumental that has all four powers of the other Vellumentals. After his first defeat, he expresses anger at Olivia siding against him and annoyance at his defeat, before showing his "true power of Origami", by turning into a massive Origami version of herself. He gets defeated again by Mario, Olivia and a transformed Origami Bowser, but Olly again emerges at a gigantic size. However, with Mario and Olivia's power, Olly is defeated once and for all.

King Olly then shows his true remorse at what he has done, and decides to grant them a wish using the Thousands Cranes technique - folding 1,000 paper cranes to get a wish - to compensate for his misdeeds, even telling Olivia to fold his body into the final crane. As 999 cranes were folded by Olly himself, the Origami Craftsmen and Olivia fold Olly and complete the wish - to undo all of King Olly's origami folding.

Abilities
Owing to his being made of origami, he is capable of shapeshifting, utilizing it to disguise himself as a yellow origami Shy Guy to infiltrate Peach's Castle, and also to utilize the appearance of the four elemental Vellumentals. He also was capable of reality-warping, an extension of his origami-related abilities, which when fueled by his rage can also cause poison to emerge.
