Cappy's main function is the 'capture' ability, which allows Mario to assume possession of enemies and other objects, which is used to solve puzzles and progress in the game. In Odyssey, Mario explores various kingdoms and collects Power Moons hidden inside them, which is used as a source of fuel to power 'The Odyssey', an airship, to travel to new locations.
In contrast to the linear gameplay of prior entries, the game returns to the primarily open-ended, 3D platform gameplay featured in Super Mario 64 and Super Mario Sunshine. An entry in the Super Mario series, it follows Mario and his new ally Cappy-a sentient hat that allows Mario to control other characters and objects-as they journey across various kingdoms to save Princess Peach from his nemesis Bowser and his plans of forced marriage. Super Mario Odyssey is a 2017 platform game developed and published by Nintendo for the Nintendo Switch video game console.
