A character appearing in Kirby: Right Back at Ya!, first seen in the episode Crusade for the Blade. Silica is the daughter of Garlude, the Star Warrior killed by Kirisakin while trying to obtain Galaxia the sword with Meta Knight. She wields a multi-purpose transforming weapon. Impulsive and hot-headed, she was intially led to believe that Meta Knight left her family to die to take the sword for himself, and attacks Meta Knight for it, but eventually learns the truth from the sword and teams up with him to destroy Kirisakin. She helped the Halberd's final assault upon Nightmare's Fortress in the final episodes.
Kirisakin is an immensely powerful mercenary monster, fought during the war where Star Warriors went against Nightmare. He was hired by Nightmare Enterprises to attempt to steal Galaxia, the same sword that Meta Knight and Garlude were sent to retrieve. They met in combat and Kirisakin took Garlude's life, but Meta Knight managed to escape with Galaxia. A very long time later, during the events of Kirby: Right Back at Ya!, Customer Service sent him to track down Silica, the daughter of Garlude, after a tip-off by King Dedede. He bested Meta Knight, Sword Knight, Blade Knight, Silica, and Kirby before Kirby managed to get his hands on Meta Knight's Galaxia and finish him off with a sword beam.
