|First game||Kirby: Triple Deluxe|
Taranza made his debut appearance in Kirby: Triple Deluxe. He has made no other appearances since then.
In Kirby: Triple Deluxe, Taranza serves Queen Sectonia and helps her in her plot to overtake Popstar. When the People of the Sky threw down the seed that grew into the Dreamstalk, Taranza captured them and locked them into cages that can later be found on Level 6, Royal Road. Once the Dreamstalk grows, Taranza climbs down it in search of the hero of Dreamland so that he can apprehend them and prevent them from interfering. However, he mistakes King DeDeDe to be the hero and storms his castle, capturing him. Taranza is seen carrying King DeDeDe in a purple web in a cutscene at the start of each boss level. He will stop for a moment in order to use some kind of magic in order to bring the boss to Kirby. He will then make his escape as Kirby fights the boss.
On the Royal Road boss level, Taranza sets the unconscious DeDeDe down and tells Kirby that he can have his precious hero of Dreamland back. He then uses magic to revive King DeDeDe and control his mind. He puts a stone mask on DeDeDe's face and then uses webs as puppet strings to control him during the boss fight. When Kirby defeats King DeDeDe the first time, Taranza becomes shocked but quickly uses more magic to revive DeDeDe once again, forcing Kirby to fight Masked DeDeDe's Revenge. During this second pahse, Taranza will actually help DeDeDe throughout the fight by providing him with magic orbs to launch at Kirby with his newly acquired axe.
After Kirby wins the boss fight, Taranza realizes that Kirby is the real hero. He summons Queen Sectonia to his aid only for her to blast him out of the sky for failing his orders.
He is later seen again during the Queen Sectonia boss fight in Eternal Dreamland when Queen Sectonia, now fused with the form of the Dreamstalk, apprehends Kirby with a vine. He carries King DeDeDe through the air to Kirby's aid, tossing him towards Kirby so that he can free him. After Kirby has been freed, Taranza produces a Miracle Fruit and hurls it at Kirby, granting Kirby the Hypernova ability and the means to defeat Queen Sectonia once and for all.
During the ending scene, Taranza dives down through the air to catch King DeDeDe as he falls out of the sky. Taranza catches him and lowers him safely to the ground.
- Taranza is most likely based on a tarantula spider, since he uses webs to capture and control King DeDeDe, has six arms, and wears a hat that bears two extra eyes (spiders can have four). His name also sounds similar to tarantula.
- Taranza becomes an ally of Kirby after he is betrayed by Queen Sectonia.
