Corrected entry: In the first film, Woody fends of Sid's mutant toys with Buzz's karate-chop mode, which is activated by pushing the purple button on the back of Buzz's jetpack. This film shows that his jetpack is his battery compartment and there are no physical connections between the purple karate chop button and the rest of Buzz's body that would allow it to control his karate chop.

Correction: The button on the pack depresses to press another button embedded in Buzz's actual back.
