As a young foot soldier in the early Joe Wars, Walter Fitswalter proved that he could get what was needed to where it needed to be in record time and without a lot of fuss. As Master Quarter Master of the Small Armed Forces he became known as "Fats" not because of his own sizable girth, but due to the fact that crews under his supervision knew they would never want for proper supplies.

Fitswalter is a superior coordinator of facilities and his Department of Transportation and Teleportation is rightly considered the able backbone of the entire Smallonaut effort.
