Buzz Lightyear's original name was Lunar Larry.
As with most initial design concepts, they tend to change over time. What Disney fanatics may not be aware of is the fact that Buzz Lightyear was originally named "Lunar Larry," and his early sketches look almost unrecognizable from the Toy Story fan favorite that audiences have come to know and adore. Lunar Larry doesn't quite have the same ring to it as Buzz Lightyear, but early sketches are interesting reminders of just how far the Buzz Lightyear development has come.
As seen in early designs (pictured above), Lunar Larry features the "LL" insignia on his spacesuit, which shows the complete redesign of Buzz Lightyear's entire concept -- including the name -- to give life to the image that Disney ultimately agreed upon. Other vastly different appearances were considered for the character alongside many sketches that slowly amounted to the final rendition of the loveable space ranger. As the images progressed, the character began to resemble the irreplaceable Buzz Lightyear.
