Principal Benjamin "Benny" Krupp, better known as Nice Mr. Krupp to differentiate him from his original counterpart, or his supervillain alter-ago Captain Blunderpants, is the secondary antagonist in Captain Underpants and the Preposterous Plight of the Purple Potty People, the eighth installment in the Captain Underpants book series.
He is a version of Mr. Krupp who hails from the Purple Potty dimension.
His Evil Ranking[]
His Villainous Deeds[]
- Stealing different cool stuff that Evil George and Evil Harold want until they have the most luxurious and cool treehouse. Things turned out a lot worse he was almost arrested and caused two trucks filled with chocolate and peanut butter to crash that radioactively mutated him and gave him superpowers.
- He travels into the prime universe, alongside Sulu and his George and Harold, being around the Purple Potty when prime George, prime Harold and Crackers go back to their universe. Upon realizing this, Evil George and Evil Harold decide to go after their counterparts and turn Mr. Krupp back into Captain Blunderpants so they can cause as much havoc as they can.
- Breaking into the prime George's garden and sneaking inside the treehouse, where they find the Goosy-Grow 4000 and use it to enlarge Sulu to colossal proportions, setting him free over the city of Piqua, Ohio and allowing him to destroy several buildings, which endangered several people and may have killed a few.
- Taking the opportunity, alongside Evil George and Evil Harold, as Captain Underpants faces Sulu, to rob a bank for the sake of it. This crime would have an impact for the rest of the series, as the prime universe's Piqua Police Department would mistake the prime George, the prime Harold and the prime Mr. Krupp for their evil counterparts, leading them to be framed for something they didn't do and setting a chain of events that:
- In the original timeline, resulted in Mr. Krupp being send to prison and George and Harold being send to juvenile detention, which allowed Tippy Tinkletrousers to escape from prison with Krupp, inadvertently alter the past and create a catastrophic present devastated by the Evil Zombie Nerds, which would have stayed that way had Tinkletrousers not time-travelled back to undo his mistake.
- In the new timeline, which was caused by Tippy time-traveling to the moment George and Harold were about to be arrested, this led to the authorities looking for George, Harold and Mr. Krupp despite their innocence for months until they gave up (as they had time-traveled to the Cretaceous age) and likely concerning their acquaintances, the Purple Potty's destruction and the deaths of Sulu and Crackers to save the universe to save everyone from Tippy's omnicidal threat, orphaning their eggs.
- Trying to go against Captain Underpants in what would have been a destructive battle before the prime George and the prime Harold turn him back into the Good Mr. Krupp, and once a storm reverts Captain Underpants into Mr. Krupp and Good Mr. Krupp into Captain Blunderpants, they then take them after their prime counterparts to get rid of them.
- Trying to kill the prime George and the prime Harold in the thunderstorm, and would have succeed if it wasn't for Great-Granny Girdle and Boxer Boy.
Why He Doesn't Stand Out?[]
- He fails the heinous standard to Evil George and Evil Harold, who were the ones who brainwashed him into a villain in the first place. Additionally, all his evil deeds were done directly under the boys' orders.
- He has severe moral agency issues due to being under hypnosis. Captain Blunderpants' morality problems are even worse than Captain Underpants' since he barely has a personality aside from being wrathful and sadistic.
- He is a villain by proxy as he is only a villain due to hypnosis.
- His split personality being the Nice Mr. Krupp makes him On and Off.
- He has a comedic defeat by being beaten up by Great-Granny Girdle and Boxer Boy, being hit on the head with a walker and hit in his eyes with a cane.
