Theodore Murdsley is the main antagonist of Captain Underpants and The Flustering Mindless Woe of the Flushable Memory Wipes
He was once a student at Jerome Horwitz Elementry. He gained the nickname Ted Turdsley because of an incident where he sat in some pudding.
HistoryAs a child, Theodore Murdsley was part of the school band. He played the glockenspiel. At one of his concerts, he sat in some pudding. When he stood up someone shouted out that it looked like he pooped his pants and then said "Hey let's call him Ted Turdsley". Afterward, a video of the incident was kept in his student file. A picture of it was used as his yearbook photo with the statement "You all will pay for this!". The joke continued for a long time and Theodore would never forget it. From then on every time someone would sit in the pudding they would become the new Ted Trudsley. This tradition reached the point where Mr. Krupp would create assemblies just to publicly announce who the new Turdsley is.
At some point, later in life, he would become a toiletries salesman and for an indefinite amount of time worked directly with his former school to get toiletries into the building.

This cleans their bottoms and their memories. With their memories gone Teodore Mursley convinces them he is principal and super awesome. When George and Harold reappear and reveal they know about everything in a school assembly Mr. Murdsley orders everyone to attack them. When George and Harold try to reveal the truth he wipes there memories and takes away their comics.
