Barbaric Officer Chirakashizky is an officer of the Banki Clan Gaiark serving as Pollution President Babatcheed's right-hand man and the secondary antagonist of the episode "Dimension on the Other Side" of Kaizoku Sentai Gokaiger.
Kaizoku Sentai Gokaiger
He originally joined the Gaiark because of how cool the name sounded.
Chirakashizky led the Gaiark forces that had fled into the Gunman World. He had previously fought against the Engines and defeated them.
When the Gokaigers went to confront him, Chirakashizky challenged them to a duel. After being defeated by the Gokaigers, Chirakashizky was enlarged but was defeated again by the Gokaigers in GokaiOh.
After his demise, his superior Babatcheed revealed that he had used Chirakashizky to lure out the Gokaigers into the Gunman World and sealed it off, leaving the Human World undefended and free for the Gaiark to invade.
