The Schwartz (a parody of the Force from Star Wars) is a supernatural force that Yogurt is the keeper of. It consists of the "Upside" (good) and the "Downside" (bad). Some of its actions include manipulating and moving objects, creating energy blades, shooting out energy bolts and beams, and even projecting another's appearance and voice over themselves, though a robot like Dot Matrix can scan a user and see beyond their false appearance. People who have the Schwartz channel it through Schwartz-rings, although users with the Schwartz in themselves do not need the rings. The Schwartz also has a physical form in the form Liquid Schwartz, which fueled the engines of Eagle 5 beyond its regular capacity after Lone Starr and Barf poured it into the gas tank.
