His Dishonor, The Mayor is the primary antagonist in the live-action/stop motion segment Action League Now! seen on Nickelodeon's All That, and KaBlam!. He wants to take over the world and his reason for hatred of the Action League is never revealed, nor how he has managed to stay in office (or if he even is an elected official, to begin with).
Trivia
Jim Krenn voiced The Mayor in the style of [at the time of the show] Pittsburgh, Pennsylvania mayor Tom Murphy.
The Mayor also makes one appearance in the Henry and June segments of KaBlam! in the Season 2 episode "Tastes Like Paper!," in which he poses as the network's director of research, subjecting Henry and June to numerous degrading and dangerous acts under the guise of "boosting ratings" as part of a plot to be able to turn the page. When Henry and June realize his entire plan revolved around this, they readily let him turn it to Life with Loopy. They then use the marching band suggested by his "research" to run him over as seen earlier in the episode.
