The Blast-o-Matic, being aimed at Donkey Kong Island
“While you'll be busy looking for your precious Golden Bananas and your flea-bitten friends, I'll be preparing my lizard flavored surprise! MWA HA HA HA HA HA HA HA!!!
King K. Rool, Donkey Kong 64

The Blast-o-Matic is a powerful weapon King K. Rool attempts to use to destroy Donkey Kong Island during the events of Donkey Kong 64. It was designed by the weasel technician Snide, who is deprived of the weapon's blueprints and his membership in the Kremling Krew by K. Rool before the game begins. Sometime later, the Blast-o-Matic is incorporated into Crocodile Isle, K. Rool's mobile base of operations, but is damaged when Crocodile Isle collides with a rock near the island. To buy time to repair the weapon, K. Rool imprisons Diddy Kong, Lanky Kong, Tiny Kong, and Chunky Kong and confiscates Donkey Kong's Golden Banana hoard. While this works as intended, the Blast-o-Matic is eventually disabled through the Kongs' efforts in Hideout Helm.

Failure to shut down the Blast-o-Matic (or selecting the "Quit Game" option from the pause menu) results in a cinematic of K. Rool laughing as the Blast-o-Matic prepares to fire at Donkey Kong Island.

According to blueprint pieces, this weapon is worked on a main computer, generated by five reactor chambers and protected by double drums in each chamber.

Years later, the Blast-o-Matic appears as K. Rool's Final Smash in Super Smash Bros. Ultimate, in which the game over scene from Donkey Kong 64 is recreated, 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. It also appears as a collectible spirit.

  • The Blast-o-Matic is mentioned in K. Rool's trophy description in Super Smash Bros. Melee.
  • The Blast-o-Matic was named the "Super Gun" in a prototype build of Donkey Kong 64.[1]
  • Elements of the Blast-o-Matic's design resembles the Big-O-Blaster from Banjo-Tooie, and even had a similar purpose and naming convention. As both Donkey Kong 64 and Banjo Tooie were created by Rare within the same time period, the similarity was most likely intentional.
