Ulysses S. Powell, being a veteran of the American Civil War, wears a Union dark blue uniform with hat on his head. His pants are gray, and he has a simple smile and eyes on his face.
Ulysses S. Powell is an inventive and curious man. He is always looking for ways to make everything better, then he heads off and builds a wild invention that he thinks will make society better. He was a member of the Union army, but didn't see much combat during the American Civil War, considering he volunteered late into the war. According to When Barrels Fly, he is also the first man to use the elusive "time portals," which first sent him back to the Cretaceous Period, then to the present day after soccer player Peter Whitman showed up. This is how he gets a job working under scientist Dr. Cyber.
- This character is named after famous Union general Ulysses S. Grant and Medal of Honor: Allied Assault protagonist Lieutenant Powell.
- Originally created as a one-time character in the twenty four hour period that When Barrels Fly was made in, he is increasingly becoming a main-stay character for Mustache Maniacs Film Co.
- It is unknown if Ulysses S. Powell would have appeared in Making Tracks. However, because of the time period in which the film takes place, it is likely.
- According to official canon and the canonized fan film A Greater Cost, Ulysses S. Powell was a foot soldier in the Union Army.
