For Buzz Lightyear, Pixar just doesn’t really seem to care about that specific plot hole and they really don’t think anyone else should care either.
One famous Toy Story plot hole involving Buzz Lightyear has been officially addressed.
Pete Docter also directed Monsters Inc., which is where another popular Pixar plot hole comes from.
Just about anyone who has seen Toy Story more than once has wondered why Buzz Lightyear goes rigid when people are around if he doesn’t truly believe he is a toy.
