According to XR, he failed to pass a certification test for the laser drill aboard Team Lightyear's ship due to spelling errors and neatness in " Sunquake", and in " Gravitina", Buzz is annoyed that XR sent Gravitina the love letter without letting him proofread it.

A running gag in the series involves XR being constantly blown up, but this proves to be little more than an inconvenience rather than a serious problem. Regarding the design of Lightyear, Toy Story director John Lasseter said he wanted to create an action figure in the line of G.I. Joe for the film and decided upon a spaceman figure.
