Skins

Skins are cheats that change the player's look. They could give Ratchet, Clank, Qwark and Nefarious different outfits and even change them to look like another playable character. Skins could be bought using titanium bolts, Dread Points, hero bolts or gold bolts. Some skins could also be equipped in the cheats menu by acquiring a certain amount of skill points. There were also skins in the multiplayer.

Trivia

 * In an unlockable feature of Tools of Destruction called Tools of Production, an Insomniac Games worker hinted that a Clank suit for Ratchet, with Ratchet on his back, was canceled from Ratchet & Clank Future: Tools of Destruction. However he also hinted that this may be put in future games. Coincidentally, there's a cheat in Secret Agent Clank that makes Clank carry Ratchet on his back.
 * Skins have no effects on armor, health, or damage. They are just for a bit of fun.
 * In Ratchet & Clank: All 4 One, Dr. Nefarious only has six skins while Ratchet, Clank, and Qwark all have seven.
