Ratchet is a main character in Ratchet & Clank series for the Playstation 3,Playstation Portable and Playstation 2.He is the sole surviving member of the Lombax species with in his universe. Ratchet discovered his accomplice, Clank after the small robot crash landed on the planet Veldin. Ratchet does most of the fighting for the pair, and instead relies upon Clank as more of a sidekick after the small robot crash landed on the planet Veldin, but there are instances where Clank will have to save Ratchet.
Ratchet is a very humorous being, one that always looks at events lightheartedly and with no sense of danger or worry. He is quite small, but also very athletic, as evidenced by his running and jumping abilities. It is said that his species is very comfortable with technology, and Ratchet seems to echo this. The Lombax relies on his friend Clank to do most of the intellectual work throughout their adventures. This may not be because Ratchet is unintelligent, but rather because he often makes spontaneous decisions, and is focused on combat.
Ratchets personality underwent a massive change from the first game to the second after being criticized for Ratchets cocky attitude making him an "Unlikable Character". Insomniac took this to heart and changed everything about him from his appearence and attitude all the way to the voice actor of Ratchet.
