Ratchet and Clank

History
(Warning-contains spoliers)

Before the beginning of his first adventure, Ratchet was finishing the construction of his ship. Dreaming of wild adventures in the galaxy, the Lombax was quite disappointed when HelpDesk informed him that he would need a robotic ignition system to start his ship. However, Ratchet noticed a ship falling from the sky which crash-landed onto the Kyzil Plateau, and upon exploration of the debris, found an unconscious Clank. The diminutive robot showed (after startling the Lombax by suddenly waking up) Ratchet an Infobot video of Chairman Drek's plans of destroying the planet Novalis to make a new planet for his species, the Blarg. Clank helped Ratchet start his ship in return for a trip to Novalis, where the little robot began looking for the hero Captain Qwark, in order to stop Drek's plans. Ratchet decided to go along for the adventure.

Ratchet's ship crashed on Novalis, but according to the official statement in the game's Sketchbook feature (in the Goodies menu), nobody really knows why. They got to talk to the planet's chairman in order to borrow his Courier Ship and obtained coordinates for the capital city of the planet Kerwan, Metropolis. After talking to the Plumber, they also received an Infobot of Skid McMarx and his agent being shot down over the planet Aridia.

Ratchet completed Captain Qwark's physical fitness course on Kerwan and should have won a Swingshot from Helga for his efforts, but after "disgracing" the course, she made them pay 1,000 bolts for it. After finding out from Big Al that Captain Qwark was no longer on Kerwan, Ratchet received an Infobot for planet Eudora.

The pair had several adventures together and generally got along well, until they met Captain Qwark at his base on Umbris. Ratchet felt that something wasn't quite right, but Clank was eager to trust the Captain. Qwark betrayed them and left them to be food for his pet Blargian Snagglebeast. After defeating the Snagglebeast, Ratchet became increasingly bitter and hostile towards Clank for leading him right into a trap, and obsessed with getting revenge on Qwark. After fighting Qwark in a Blarg ship at the Gemlik Moonbase and seeing the devastation of a nearby planet at Drek's hands, Ratchet finally realized that Drek had to be stopped and made amends with Clank.

After a fierce battle, Ratchet sent the Chairman flying up to his newly-created planet and destroyed it. Flaming chunks hitting the Deplanetizer's control pad knocked Ratchet and Clank off, and only Clank's quick thinking stopped them from hurtling down to the Plateau below. However, the servos in his arm were broken from supporting Ratchet's weight and they both fell. Once again, Clank saved Ratchet's life by using his Thruster-Pack upgrade (installed by Bob on Pokitaru) to break the Lombax's fall. Ratchet then started to walk off, to Clanks disappointment. However, just as Clank was about to leave, Ratchet returned, and offered to repair Clank's broken arm. Ratchet and Clank became a team.

Later, the two watched an advertisement for Qwark's Personal Hygenator; horrified and disgusted by its effects, Ratchet shouted at Clank to turn the TV off.

Description
Ratchet is a Lombax native to the planet Fastoon (later sent to Veldin). He is the main protagonist of the Ratchet & Clank series. Ratchet is 5 feet tall, and, as of Ratchet: Deadlocked, weighed 97.5lbs (44.3kgs). In Ratchet & Clank, Ratchet is voiced by Mikey Kelley. In the following Ratchet & Clank games, he was voiced by James Arnold Taylor. He is also the son of Kaden, who was killed shortly after Ratchet's birth.

Ratchet is a street-wise, wrench-swinging guy who always loved to get into an adventure without really thinking about the risks or odds. He made many sarcastic comments or jokes and could take things personally, but over the series of the games, Ratchet seemed more matured and serious. He enjoyed swinging down Zip-lines and using his Swingshot.

Ratchet, like many Lombaxes, is also known to have invented many items, some of which were more successful than others. These items included Stunderwear, amongst many others.In the first game, Ratchet was very selfish, arrogant, and self-absorbed and Clank had to talk him into helping other planets. Throughout the course of the game, however, he became more dedicated and serious to stopping Drek's plans. He was described as a practical joker by his best friends, and had an ambition of becoming a space explorer. After that, he became a less selfish person, and a more likeable character. He became very selfless, and at the end of Deadlocked was willing to give up his life for all the captured heroes that he eventually saved. In A Crack in Time, Ratchet was seen as intelligent, humble and serious.
