Sergeant Boxers is a minor character in the series. He's the alter ego of Kenny B. Meaner created by Harold and George. He doesn't seem to appear in the books.

He and his alter ego are voiced by David Koechner in the TV Show The Epic Tales of Captain Underpants.


Sergeant Boxers is pretty much like Captain Underpants, except he loves weight lifting and sports, he's also created by Harold and George using the Hypno-Ring the same way they created Captain Underpants, they hypnotize Mr. Meaner first making him a rhythmic gymnast, then Sergeant Boxers, he only turns that way if Harold and George snap their fingers like it does with Captain Underpants, his catchphrase is Too-de-loo, similar to Captain Underpants catchphrase, Tra-la-la, possibly water as well turns him back into Mr. Meaner like it does with Captain Underpants turning back into Mr. Krupp, his face is painted half purple and half orange, he wears 1 sock, and wears a purple cape with a whistle attached. He thinks that he's really Sergeant Boxers after being hypnotized by Harold and George, he kind of acts and becomes stupid like Captain Underpants but in different ways, because they have 2 entirely different personalities, but they both try hard learning how to follow Harold and George's rules. Sergeant Boxers doesn't seem to turn back into Mr. Meaner at the end. Harold and George add Sergeant Boxers to their comics and he meets Captain Underpants that way instead of in person.
