Masked Dedede appears once again as a boss in Kirby: Triple Deluxe, this time controlled by Taranza and is one of the last bosses in the game, only succeeded by Queen Sectonia and her other forms. The first phase is somewhat similar to his first appearance but, in the second phase, he uses a poleaxe.
In Extra Mode, since the player is Dedede, they face Shadow Dedede who has many similarities.
His attacks consists of upgraded moves as well as new additions such as spinning his hammer around, firing missiles, and spewing flames. Also, his boss theme is a remix of his regular theme.
