General profile

Olivia, known in Japan as Oribia, is the principal supporting character and primary party companion of Paper Mario: The Origami King for Nintendo Switch (July 2020). An origami sibling to the game’s antagonist King Olly, Olivia is a small, pink, flower-shaped origami figure with a sweet round face, blue inner-petal details, and a perpetually cheerful disposition. She joins Mario’s adventure to oppose her older brother’s scheme to fold the entire Mushroom Kingdom into origami form, and her sibling rivalry with Olly forms the emotional core of the entire Origami King narrative. She stands at approximately half Mario’s height and has been canonised as one of the most charismatic Paper Mario partner characters of the modern era.

Olivia’s gameplay role in The Origami King is multifaceted. She functions as Mario’s talking party guide — always present throughout the game’s adventure, delivering lore exposition, character commentary, and tactical hints — and as a transformable combat assist. Her ability to fold and transform into various origami constructs (including a giant hammer, a thousand-fold crane, and a giant arm) provides Mario with unique combat support not available in any previous Paper Mario entry. Her transformations are deeply integrated into the game’s combat and exploration mechanics, making her one of the most gameplay-essential party characters in the Paper Mario series.

Olivia’s defining narrative role is as the empathetic counter-voice to King Olly’s villainy. While Olly seeks to fold the entire Mushroom Kingdom into rigid origami forms (eliminating the messy diversity of paper-Mario life), Olivia represents the opposite philosophy — acceptance, friendship, and the joy of imperfection. Her emotional reactions to her brother’s scheme — grief, sorrow, hope, and ultimate reconciliation — form the most affecting character arc in the Paper Mario series. The ending of the game, in which Olivia must make a final tragic choice regarding her brother’s fate, has been frequently cited as one of the most emotionally devastating moments in modern Mario series storytelling.

Quotes

Enemies

Olivia’s primary enemy is her own brother King Olly — the antagonist of Paper Mario: The Origami King, whose origami-folding scheme threatens to consume the entire Mushroom Kingdom. The sibling-versus-sibling conflict forms the emotional core of the game’s narrative. She also opposes the Folded Soldiers, the elite origami legion serving Olly’s cause; the Legion of Stationery (Olly’s elite weapon-bosses including the Pencils, the Hole Punches, the Rubber Bands, the Scissors, the Tape, and the Stapler); and the various boss creatures encountered throughout the eight-region journey across the Mushroom Kingdom.

Friends

Olivia’s closest companion is Mario, whom she partners with as the primary party throughout the entire game. Their friendship has the dynamic of supportive-and-supported allies: Mario provides the combat capability and platforming skills, while Olivia provides the emotional support, navigation guidance, and tactical advice. She develops warm friendships with several recurring companion characters: Bobby the Bob-omb (a memory-loss-affected Bob-omb who becomes a major emotional anchor), Kamek (briefly an unwilling ally), Professor Toad (the academic-archaeology Toad), and Luigi (briefly encountered). Her relationship with Bobby is particularly significant — their friendship arc is one of the most-praised character interactions in Origami King.

Appearances

Paper Mario: The Origami King (Switch, July 2020)

Olivia debuted in Paper Mario: The Origami King for Nintendo Switch (July 2020), developed by Intelligent Systems. The game is the sixth Paper Mario entry and the first to be released on a home console since 2007’s Super Paper Mario. Olivia is introduced in the game’s opening sequence: Mario and Luigi visit Princess Peach’s castle during the Origami Festival, only to discover that the castle has been folded by King Olly into a giant origami castle. Olivia escapes from her brother’s control and seeks out Mario as her ally to oppose her brother’s scheme.

Olivia Freed from Captivity (2020)

After being freed from King Olly’s control through Mario’s rescue efforts, Olivia commits herself to opposing her brother’s scheme. The freeing scene establishes her cheerful, optimistic personality and her sibling-conflict motivation. Her partnership with Mario begins from this point and continues across the eight regions of the Mushroom Kingdom that the game’s campaign traverses.

Olivia’s Transformations (2020)

Olivia’s defining gameplay capability is her ability to transform into various origami constructs to assist Mario. Her transformations include the Giant Hammer (her most-frequently-used form, for combat and puzzle-solving), the Thousand-Fold Crane (an aerial transformation for boss-fight phases), the Giant Hand (for grabbing and pulling environmental objects), and various smaller-scale folds. Each transformation is animated with elaborate paper-folding sequences and provides unique gameplay mechanics not seen in previous Paper Mario entries.

The Journey Across the Mushroom Kingdom (2020)

Olivia accompanies Mario on a journey across the eight regions of the Mushroom Kingdom — from the Whispering Woods through the Autumn Mountain to the Sea, the Origami Castle, and beyond. Each region features unique enemy encounters, boss fights against the Legion of Stationery, and lore-exposition cutscenes. Olivia’s commentary and emotional reactions throughout the journey form one of the most-praised character-writing achievements of the modern Paper Mario series.

The Origami Festival Setting (2020)

The game’s setting — a Mushroom Kingdom celebrating the annual Origami Festival, during which King Olly has corrupted the festival’s ceremonial paper-folding tradition into a kingdom-wide invasion — is one of the most thematically coherent setting designs in the Paper Mario series. Olivia’s relationship to the Origami Festival’s cultural significance — as the cheerful celebrant of origami art versus King Olly’s tyrannical re-purposing of the same tradition — forms a sophisticated thematic exploration of how cultural traditions can be corrupted by ideology.

Olivia Craft Promotion (2020)

Nintendo’s 2020 pre-release marketing for Paper Mario: The Origami King featured downloadable origami-craft instructions for fans to fold their own paper Olivia figures. The craft promotion was widely shared on social media and helped establish Olivia as one of the most-marketed new Paper Mario characters of the modern era.

King Olly (Antagonist Brother)

Olivia’s brother King Olly is the principal antagonist of The Origami King. Olly is a larger, more ornate origami figure than Olivia — a crown-shaped origami king-figure with elaborate folding details and a perpetually frowning face. His scheme to fold the entire Mushroom Kingdom into origami form is driven by a deep-seated belief that flat paper Mario residents are inferior to properly-folded origami beings. The sibling conflict and eventual reconciliation between Olivia and Olly forms the most emotionally significant character arc in modern Paper Mario history.

Trivia & Official Sources

• Olivia was designed by Intelligent Systems’ art team led by Naohiko Aoyama for Paper Mario: The Origami King (2020). The character’s pink, flower-shaped origami design was inspired by traditional Japanese origami techniques, with the petals representing optimism and the round face representing innocent cheerfulness.
• The Japanese name Oribia (オリビア) is a feminine-name play on "origami" — combining the species-name "ori" (from origami) with the "-bia" feminine suffix. Her brother’s name "Olly" uses the same prefix with a masculine suffix.
• Olivia is the first origami-species major party character in the Paper Mario series. Previous Paper Mario partners (Goombella, Koops, Madame Flurrie, etc.) have been paper-flat species variants rather than origami-folded figures.
• The Pix’n Love Encyclopedia Super Mario Bros. (2018) does not include Olivia because she debuted in 2020 after the Encyclopedia’s 2018 publication. She will be included in subsequent updated editions.
• Olivia’s transformation ability — her power to fold herself into giant origami constructs to assist Mario — is one of the most innovative party-character mechanics in the Paper Mario series. The mechanic was widely praised by reviewers as one of the standout gameplay innovations of The Origami King.
• Paper Mario: The Origami King (2020) sold approximately 3.5 million copies worldwide in its first year, making it one of the best-selling Paper Mario series entries. Olivia’s introduction in this game has made her one of the most-recognised modern Paper Mario characters.

• Olivia’s relationship with Bobby the Bob-omb — a memory-loss-affected Bob-omb who becomes one of her dearest friends — is one of the most-praised supporting-character arcs in The Origami King. Bobby’s eventual fate has been described by reviewers as one of the most emotionally devastating sub-plot resolutions in Mario series RPG history.
• Olivia’s cheerful, optimistic personality is a deliberate creative inversion of typical "cute girl sidekick" templates. She is consistently characterised as having genuine emotional depth, with grief, sorrow, and hope all being major plot points rather than merely cheerful enthusiasm.
• The Origami Festival setting of The Origami King was inspired by traditional Japanese seasonal festivals — particularly the autumn-themed Tanabata and similar paper-folding traditions. Olivia’s cultural relationship to the festival forms part of the game’s thematic exploration.
• Olivia’s combat transformations — the Giant Hammer, Thousand-Fold Crane, Giant Hand, and various smaller folds — are animated with elaborate paper-folding sequences. The animation work has been frequently cited as some of the most technically impressive in the Paper Mario series.
• Olivia has not appeared in any Smash Bros. entry as either a fighter, Mii Fighter costume, or Spirit as of late 2025. The character’s 2020 introduction in The Origami King post-dates her potential inclusion in Smash Ultimate’s base roster.
• The character has been featured in Nintendo official merchandise including a 2020 origami-craft promotional kit and various plush toys released in Japan. Olivia merchandise has been one of the most popular post-Origami-King launches in the Paper Mario series merchandise line.
• Olivia’s in-universe height is approximately half Mario’s height, making her one of the smaller party companions in the Paper Mario series. The diminutive size emphasises her vulnerability and contrasts with the emotional weight of her sibling-conflict storyline.
• The character has not been confirmed to appear in The Super Mario Galaxy Movie (April 2026) as of late 2025 pre-release marketing. The Paper Mario party characters’ film-adaptation status remains one of the open questions for Illumination’s Super Mario film series.
• King Olly, Olivia’s brother and the principal antagonist of The Origami King, is rarely portrayed as completely evil — his motivations are presented sympathetically throughout the game. Olivia’s eventual reconciliation with him in the ending sequence is one of the most thoughtfully-written villain-resolution arcs in the Mario series.
