The Shape Stealer was created by Brain Pod 11 under the codename Project X. Zurg was originally unimpressed with it until it revealed itself by taking over one of Zurg's Grubs as a demonstration. From there, the Shape Stealer took over various people in an attempt to assassinate Buzz Lightyear. Eventually, it ended up on Star Command and took over Buzz himself. It was sent into space by Mira Nova. It is unknown where the Shape Stealer is now.
