Clank
"Have I ever told you about my son? Remarkable boy. Quite smart! He was born in a robot factory in the Solana Galaxy, but to be precise, he was created much farther away. My son's name is XJ-0461, but the universe knows him as Clank." --Orvus[src] Clank, real name XJ-0461,[1] is a small robot, programmed with artificial intelligence, and Ratchet's long-time companion and best friend and the deutragonist of the Ratchet and Clank series. He was born at the Robot Factory on the Planet Quartu but was created in the Great Clock. While Clank's serial number was B5429671, the name "Clank" emerged when Ratchet caused his handmade ship to rock while flying to Planet Novalis, causing the small robot to hit the side of the ship and making a clank sound. This became his nickname throughout his adventures with Ratchet.
The Zoni referred to Clank as the "Chosen One". Clank's creator was a Zoni named Orvus, who regarded his creation as a son.[2] After finding himself in a gigantic Zoni-made machine known as the Great Clock, Clank became the Senior Caretaker of the Great Clock. But eventually realizing that he must reunite with his friend Ratchet, Clank later promoted Junior Caretaker Sigmund to be the Senior Caretaker in his place.
