A Bonneter from the Cap Kingdom
Cappy is a cap-shaped spirit (Bonneter officially, キャッピー / Kyappī in Japanese), a people of spectral beings whose heads look like hats. He lives in the Cap Kingdom, the very first kingdom you visit in Super Mario Odyssey: a foggy black-and-white land with Victorian touches straight out of London. It is there, in the small town of Bonneton dominated by Top-Hat Tower and its giant topper, that most of his kind live.
In his natural form, Cappy looks like a white top hat with big eyes and red irises. His personality? Energetic but a touch shy... at least until he fights alongside Mario, where he shows real courage. Once perched on the plumber's head, he takes on the look of that famous red cap and gives it a pair of living eyes: a detail that became iconic on the spot.

Tiara, Bowser and a forced wedding: Cappy's quest
Cappy's story begins with a family tragedy. When Bowser kidnaps Princess Peach to force her into marriage, he also takes Tiara, Cappy's little sister: the Bonneter is destined to become the bridal tiara for Peach at the ceremony. Thrown off Bowser's ship after a losing fight, Mario crashes down right in the Cap Kingdom.
That is where Cappy offers him a deal: join forces to rescue both captives. Perched on Mario's head, he climbs aboard the Odyssey, the hat-shaped airship that gives the game its name, for a chase across kingdoms all over the world. This unlikely duo gives the adventure a moving edge: for once, Mario is not alone, and his companion has just as much to lose as he does.

Capture: 52 ways to be Mario
Cappy's real superpower is called cap-morphing (Capture officially). Throw Cappy at certain enemies or objects and Mario literally takes control of them, inheriting their abilities. The game's own list counts 52 captures, from the humble frog — the very first one in the game — all the way to Bowser himself in the grand finale.
Among the most memorable transformations: the Bullet Bill streaking through the air, the Goomba you stack into towers, the Hammer Bro, the Sherm tank... and of course the T. rex, star of the trailers. Every captured creature sports the cap and, more often than not, Mario's moustache, a visual wink that has become a cult favourite. One subtle design rule: you cannot capture an enemy that already wears a hat — you first have to knock it off with a well-aimed Cappy throw.

Controller in hand: far more than a simple power-up
Reducing Cappy to Capture alone would be unfair: he deeply reshapes the way you play a 3D Mario.
- The throw: hurled like a boomerang, Cappy attacks enemies, picks up coins and triggers mechanisms from a distance.
- The cap jump: by throwing Cappy and then bouncing off him, Mario extends his jumps and reaches platforms that would otherwise be out of range — the foundation of every trick in an expert player's book.
- Teleportation: Cappy lets you travel instantly between the checkpoint flags you have already activated.
- Two-player mode: a second player can take control of Cappy independently, an ideal way to share the adventure as a family.
That mix makes Odyssey one of the most movement-rich Mario games in the entire saga: Cappy is not a temporary bonus like the Fire Flower, but a permanent partner who redefines every single jump.
Birth of a character: behind the scenes at Nintendo
Cappy was born... from a controller. Producer Yoshiaki Koizumi was hunting for the most natural action to perform with a Joy-Con: the throwing motion won out. All that was left was deciding what to throw. As director Kenta Motokura explained, Mario has always been a character with a cap; it was this new hat-based action that convinced the team to turn it into a full-fledged character, a travelling companion for the whole adventure.
His design is packed with clever touches: Cappy is white so that he can match the colour of any headwear, and his smiling eyes were drawn to echo the "M" on Mario's cap. The gamble paid off: Super Mario Odyssey, released on October 27, 2017 on Nintendo Switch, holds a 97/100 score on Metacritic and has passed 30 million copies sold, making it one of the console's greatest successes.

Cappy's legacy beyond Odyssey
Since 2017, Cappy has never left Nintendo culture behind, even though he stays loyal to his home game. He has turned up in several guises:
- As a collectible statue in Super Mario Run (2017);
- As a spirit in Super Smash Bros. Ultimate (2018);
- As a hat you can wear in Animal Crossing: Pocket Camp (2018);
- As a playable costume in Taiko no Tatsujin on Switch (2018).
Above all, Cappy left a lasting mark on the saga: he embodies Nintendo's knack for reinventing Mario with every generation, just like the Tanooki Suit's flight before him, or the gravity of Galaxy. One simple hat, and the entire 3D platformer formula was shaken up. Hats off, maestro.
