Clank

Clank is a fictional character in the Ratchet & Clank series. Clank is 3 feet 2 inches tall and weighs a respectable 17 pounds. His light weight is the result of state of the art nano-technology that compressed the capabilities of a 137 Teraflop supercomputer into Clank's diminutive frame. This was very fortunate for Ratchet who has the responsibility of carrying Clank's weight around on his back. If Clank were much heavier he almost certainly would have impaired Ratchet's speed and agility.

Ratchet & Clank
Clank is introduced as an Idealist robot designed by a robotics war factory computer (his mother) to save the Solana Galaxy from Chairman Drek. The computer was designed to produce worker drones, but some kind of system failiure-maybe even intentional by the computer- made Clank brainy but small and weak in strength terms. After this Clank escapes from the factory in a small spacecraft. He is forced to crash land on the planet Veldin, after being shot down, and is later found by the Lombax mechanic, Ratchet. Ratchet agrees to go with him to Novalis, a planet under attack by Drek's forces. At first the duo attempt to find the intergalactic super hero, Captain Qwark. After they find him they find out that Qwark has sent them into a trap set by Drek to kill them. Ratchet blames Clank for their misfortune, but they are forced to stay together because the ship Ratchet has to use to escape can only be started by a robotic ignition system, and Clank is equipped with this software so they continue on their journey. Ratchet eventually forgives Clank and they both defeat Chairman Drek.

Ratchet and Clank: Going Commando
In the second game, Ratchet & Clank: Going Commando (Ratchet & Clank 2, Locked & Loaded in Europe), Ratchet and Clank find themselves living a famed life of intergalactic heroes. Suddenly, Abercrombie Fizzwidget, Megacorps' founder and President, teleports the two aboard a ship and tells of his offer to make Ratchet an elite commando for Megacorp and Clank the head accountant of the company. They both accept and are sent to the Bogon Galaxy. But early in the adventure Clank is kidnapped by a mysterious thief so that Ratchet will be forced to leave the Bogon Galaxy. Ratchet saves Clank after repairing him. Later the two are captured and taken to a prison run by Thugs-4-Less. A robot girl finds Clank and escorts them out of the prison. And then on the Planet Yeedil the robot girl finds Ratchet & Clank and tries to warn them of what's ahead. Then Abercrombie Fizzwidget comes in and shoots the robot girl and captures Ratchet & Clank. After that Fizzwidget takes off his disguise to show that he is the famed superhero Captain Qwark. Qwark is then eaten by the original Protopet which he accidentally mutated with Angela's Helix-O-Morph (the battery for the device was in backwards). Ratchet kills the Protopet which results in Qwark's return, coming out of the Protopet. Ratchet sees Clank holding the girl robot, now dead, and promises to fix her.

Up Your Arsenal
In the third game, Ratchet & Clank: Up Your Arsenal (Ratchet and Clank 3 in Europe), Clank seems to have been given a job as the starrring role in the "Holovision" series "Secret Agent Clank" while Ratchet is just the chauffeur for Clank. In this game Clank seems to get more recognition from the characters, seeing as Clank is more famous. During the adventure, Clank is kidnapped by Dr. Nefarious who offers him a seat of power in the galaxy if he helps him; Clank declines the offer and is replaced by Klunk, an exact evil copy of Clank. At times, the eyes change from Clank's green to Klunk's red. Ratchet defeats Klunk and sets Clank free. After that, Ratchet defeats Dr. Nefarious and Ratchet & Clank then both go to the premiere of "Secret Agent Clank: The Movie".

Deadlocked
In Ratchet: Deadlocked, Clank's role is somewhat limited compared to the other games. Although he doesn't join Ratchet in his adventure, he serves as his Mission Engineer, updating him with constant information and help via radio. He is also given the same treatment by the Announcers/Reporters of Dreadzone, Dallas and Juanita, that they give to Ratchet, though in a lesser degree. Also, he seems to have made yet another "girlfriend", a tech droid named Venus who he gets to help him in certain ways. There is also an unlockable 'skin' for Ratchet, called Alpha Clank. It is basically a large armored body with Clank's normal head on top.
