A majority of K. Rool's ship, Crocodile Isle, consists of the Blast-o-Matic. This machine is powered by a central core, which is connected to five rooms, each with their own colored power generator; the color for each power source corresponds to one of the five Kongs. The device is capable of firing a laser from three brass rings surrounding a metal arrowhead pole. The arrow of the machine comes out from the belly of Crocodile Isle.

Prior to the game's events, Snide was the lead technician for the Blast-o-Matic. K. Rool eventually became paranoid of Snide and fired him. He lost access to the weapon's blueprints, which K. Rool split apart and handed a piece to each of the Kasplats.
The game's intro shows K. Rool heading to DK Isles, plotting to blast it with the Blast-o-Matic. However, as Crocodile Isle steers quickly on the water, it hits a rock, causing the Blast-o-Matic to break. The Kremlings work on repairing the machine for a large portion of the Kongs' adventure, having stolen Donkey Kong's Golden Bananas and kidnapped Diddy, Lanky, Tiny, and Chunky to buy time to do so.
When the Kongs enter Gloomy Galleon for the first time, a cutscene shows K. Rool telling a Kritter, the Blast-o-Matic's new chief technician, that he trusts the Blast-o-Matic to almost be ready for activation. The Kritter says the machine is unfinished, and in response, K. Rool sends out Klaptrap guards to ensure that the Kritters do not escape until they finish repairing the machine.
Later, when the Kongs first enter Creepy Castle, a cutscene shows a Kasplat trying to escape from Crocodile Isle, hoping that K. Rool does not find out about the Kongs recovering the blueprints to the Blast-o-Matic, which he describes as a "stupid machine".
Upon first entering the final world, Hideout Helm, the Kongs set off the Isle's alarm system, forcing K. Rool to use the device, even though the chief technician says it could destroy them all. The Kongs' main goal is to deactivate the Blast-o-Matic within the time limit, which varies depending on how many blueprints that the Kongs have recovered for Snide (one minute for each blueprint, up to a total of 50 minutes). To deactivate the machine, each Kong must complete two Bonus Barrel challenges just outside their corresponding power source.
Failure to shut down the Blast-o-Matic in time (or choosing "Quit Game" from the Pause Menu) results in a Game Over cinematic where K. Rool laughs madly and presses a few buttons to activate the Blast-o-Matic. The sequence stops just before it allegedly takes fire at DK Isles.

The Blast-o-Matic appears as K. Rool's Final Smash in Super Smash Bros. Ultimate, essentially as a recreation of the game over sequence from Donkey Kong 64 down to K. Rool having to press the button multiple times while laughing maniacally before it fires, only this time, the results of him firing the cannon are actually shown.
The Blast-o-Matic also appears as a Legend-class support spirit that occupies one support slot. When used, the spirit increases the damage a fighter can deal to giant opponents in battle. It can be purchased from Sheldon's Place for 10,000 Spirit Points.
