—Giga Bell, Super Mario 3D World + Bowser's Fury

Fury Bowser (referred to as "the beast" by the Giga Bells and the lighthouses throughout Lake Lapcat) is a form that Bowser takes in the Bowser's Fury campaign of Super Mario 3D World + Bowser's Fury. In this form, Bowser becomes a gargantuan kaiju, being the largest physical form he has ever taken, surpassing even Giant Bowser in size. Similarly to Black Bowser from Paper Mario: Color Splash, Bowser enters this form when he is corrupted by black goop, which causes his skin to become entirely black in color, complete with glowing yellow eyes without pupils. In contrast, his hair glows a bright red, while the center of his carapace and the tips of his shell spikes glow orange and red. It is implied by Bowser Jr.'s paintings, both when Mario first encounters him and in the credits, that the form was unintentionally caused by Bowser Jr. painting his father black and angering him.

In comparison to his normal self, his body is much larger than his head, his tail and shell spikes are somewhat longer, he has more spikes on his arm bands, and he has more defined pectoral muscles; the lattermost trait is shared by Bowser's appearances in the Super Smash Bros. series. Compared to Bowser's normal roar and even the likes of Dark Bowser's or Dry Bowser's roars, Fury Bowser's roar is much louder and deeper, and has a reverberating effect.

Fury Bowser also appears in Super Smash Bros. Ultimate as a primary, Legend-class, Attack-type spirit, introduced during the five-day "Bowser's Fury" spirit event that began on April 9, 2021. When equipped, the strength of the fighter's fire-based attacks is increased. He is represented by a Metal Bowser in his spirit battle, which takes place on the Ω form of Find Mii. The arrangement of Bowser's battle theme in Super Mario Bros. 3 serves as the battle's music.
