Cappy

"We've come a long way, you and me... We've seen a bunch of different kingdoms... I mean, sure, we got shot down and stuff along the way... But think of all the HATS! This trip really was amazing. Thank you, Mario. It's been an honor walking a mile on your head."

- Cappy

Cappy is a major character in Super Mario Odyssey. He is Mario's main ally throughout the game and assists him in various ways. Along with his little sister Tiara, Cappy is a Bonneter originally from the Cap Kingdom and joins Mario to rescue her after she is kidnapped by Bowser.

Concept and creation
Cappy's final design was colored white as he was meant to transform into various hats, and white was deemed a color able to fit all the different colors of the hats. Furthermore, his eyes while smiling were made to resemble the "M" of Mario's cap.

Super Mario Run
Although Super Mario Odyssey is the first game in which Cappy is physically present, his first appearance is in Super Mario Run. To promote Super Mario Odyssey's appearance at E3 2017, a statue of Cappy in the form of the Mario Cap was made available as one of the objects in Kingdom Builder on June 14, 2017 and costs 2,000 coins. When tapped after it is placed on the field, it changes to his original top hat form for a few seconds, while his voice can be heard exclaiming, "Cappy!"

Super Mario Odyssey
Cappy's first true physical appearance is Super Mario Odyssey, where he is Mario's main partner throughout the game. Cappy joins Mario to rescue his little sister Tiara, who had been kidnapped by Bowser along with Princess Peach. He is "energetic but a bit timid." Cappy is also controlled by the second player when playing in co-op mode.

Mario can throw Cappy in various ways; a straight up/down shot that can roll across surfaces, a circular, boomerang-like throw, and a homing throw which can also be used to extend Cappy's reach. Cappy can also be held in place once thrown. Throwing Cappy in the air gives Mario a vertical boost while canceling horizontal momentum, allowing Mario to adjust his trajectory. Mario can bounce off Cappy once per jump, significantly extending Mario's jumping reach, but he can be thrown a second time. These moves serve as an attack and defensive measure, allowing Mario to defeat enemies at a distance.

When thrown at certain enemies or objects, Cappy captures them, allowing Mario to control them to get across stages. The behavior of captured enemies and objects varies depending on the creature or object. Cappy can also interact with the environment. For example, he can pull levers, remove wooden poles, destroy some objects, and remove pools of poison. Cappy can help collect several items for Mario, such as coins and hearts. Exceptions include Power Moons and keys. In addition to Coin Blocks, Cappy can also collect items from certain environmental objects such as bushes.

Cappy also informs the player of various details of the game and the surrounding world, such as regional coins that can only be used in one kingdom.

Super Smash Bros. Ultimate
Cappy appears in Super Smash Bros. Ultimate as the Mario Cap, Mario's Top Hat and Builder Helmet, appearing during some moves and a taunt alongside Mario. However, he does not have any effect on Mario's moveset. He also appears in his Bonneter form as a support Spirit, which slightly increases the power of grabs and throws when equipped. It can be summoned using an Ezlo and Boo Mario core (which could be a reference to how Ezlo is also a cap-like creature in the original game). Cappy also appears in Mario Cap form as a hat that can be worn by Mii Fighters unlockable through a challenge.

Physical description
Cappy's normal form is a white top hat with blue wisps of hair and large eyes with red irises. Under the hat is his main body, which somewhat resembles an Eerie. When transformed into different hats, such as the Mario Cap, Cappy's eyes will appear on the hat. Cappy also comes in a variety of outfits, which can be purchased from the kingdoms' Crazy Cap stores, including a chef hat, top hat, builder hat, and a fedora. In Super Smash Bros. Ultimate, Cappy gains a subdued color scheme and simple detailing.

Personality
Cappy is a helpful, friendly, selfless, confident, and heroic character who is always there for those he cares about. However, he is a little timid and easily startled at times. Despite this, after joining with Mario, he is very bold and never backs down from a fight, such if the player chooses to leave the Wedding Hall before rescuing Peach and Tiara. When Tiara was captured, he immediately chose to join Mario and assist him in his journey. He is also talkative, frequently giving Mario advice and checking what is interesting about other kingdoms.

While in the Darker Side, he is shown to be grateful to Mario for his journey when they climb the replica of the New Donk City Hall to reach the last Multi Moon on its top.
