“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.”
Clank, real name XJ-0461, was a small defective Sentry-bot robot (later revealed to have a Zoni soul) and Ratchet’s long-time companion and friend. He was born at the Robot Factory on the Planet Quartu, where he awoke and ended up escaping. He then landed on Veldin and met Ratchet. He was created in the Great Clock by his father, Orvus.
While Clank’s serial number was B5429671, the name “Clank” emerged when Ratchet’s homemade ship rocked 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, protecting the universe from numerous evil-doers and becoming legendary heroes who always have each other backs, metaphorical and literally speaking.
The Zoni referred to Clank as the “Chosen One”. Clank’s creator was a Zoni named Orvus, who regarded his creation as a son. 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 promoted Junior Caretaker Sigmund to be the Senior Caretaker in his place, so that he could reunite with Ratchet. He could also transform into an ultra-mech. In this form, known as Giant Clank, he could shoot missiles from his arms, launch energy bombs, and punch enemies. Clank was born in the year 5354. Despite being a robot, Clank was a vegetarian.
