Capture

Capture is a unique ability Mario gains in the upcoming title Super Mario Odyssey. His newfound hat friend, Cappy, grants him this power somewhere in the Cap Kingdom, where he is presumably found. When Cappy is thrown at an enemy, creature, or object, such as a Goomba, Mario is able to take control of said enemy, creature, or object. This allows Mario to use new abilities, many of which he has never previously had, and collect Power Moons which would normally be out of his reach. When capturing something, that thing will gain Mario's hat and mustache, as well as his blue irises (if it has eyes). Mario can also "de-capture" his host at will.

Capturable enemies, creatures, and objects
The following is a list of everything Mario can capture (and their known abilities), as has been evidenced so far:

T-Rex: Nothing is definitively known, but from one screenshot, it appears that capturing this ferocious dinosaur will allow Mario to run and smash through large, normally unbreakable blocks.

Frog: Nothing is definitively known, but it can be assumed that Mario will use the frog's long legs to jump higher than usual. This is also possibly the first thing Mario captures in-game, as evidenced by the special cutscene which plays in the reveal trailer.

Goomba: As a Goomba, Mario will be able to run around and jump on top of other Goombas to form Goomba Towers.

A Hammer Bro. throwing skillets: Not much is known, but as this new enemy, Mario will be able to throw skillets at other enemies. These will break upon impact with the ground or with another Bro's skillets.

Bullet Bill: As a Bullet Bill, Mario will be able to fly around freely, but only on one plane, and must hurry, as the Bullet Bill will eventually explode (on its own - or if it runs into an obstacle). The player can also press the Y button to accelerate. Some Bullet Bills wear hats (e.g. visors in New Donk City ), and they must be knocked off before the Bullet Bills can be captured.

Rockets: Capturing a Rocket, the player can press and hold B to launch Mario the rocket into the sky (similar to how Rocket Barrels are launched in the Donkey Kong Country series). Rockets serve as transports to secret areas and back, such as in New Donk City.

Podoboo: As a Podoboo, Mario can jump and swim through the pink goop found in Mount Volbono, and uses this ability to jump through hard-to-reach Coin Rings. Mario the Podoboo can also launch himself from some sort of Podoboo cannon, as evidenced in the E3 trailer.

Binoculars: When Mario uses Cappy to capture binoculars, they will automatically blast off, shooting into the sky, tethered to their base only by a thin cord. Mario will be able to use this high vantage point to look around and zoom in on points of interest.

Electricity: Mario can throw Cappy at power lines to become electricity and zip through and across the wires, allowing for smooth and speedy transport. Mario can "de-capture" the wire at any point along the line, but can only capture the wire at special bases with lit-up lightbulbs. Once moving along the wire as electricity, Mario can only stop or change direction at these points. Otherwise, he will continue moving in the direction he faces.

Cheep Cheep: Nothing is definitively known, except that capturing a Cheep Cheep will allow Mario to swim faster underwater and with more ease.
