Nevel Amadeus Papperman
Nibbles (by Cat)
Ms. Papperman (Mother)
iCarly (Sam formerly)
Mr. Tibbals (his pet)
Gibby's replica head
Nevel was an enemy of Carly Shay, Sam Puckett, and Freddie Benson since Carly refused to kiss him in his debut appearance. Ever since then, he has tried to sabotage iCarly, but was stopped every time.
Sometime after Sam left Seattle, his mother brought him to Los Angeles to a sick hospital because his pet porcupine Mr. Tibbals infected him with a virus. Sam and Cat came to the hospital he was locked in because they were seeking help to find Dice and save him from Nora Dershlit. Nevel gave them clues to find the former, such as the donkey sauce, which came from Aloha Burgers, and that the best way to hide someone was in an abandoned house.
As Sam and Cat left, he begged them to get him out of the hospital. He is then shown to have broken out of the Hospital. Later, after Dice has been saved, he phoned Sam and told her that he is out and was having a friend for dinner. In reality, he was having dinner with a friend, which turned out to be Gibby.
Nevel is very old-fashioned when it comes to manners and words. He likes saying, "You'll rue the day!" or some other variation of him and calls his mom Mother. He is also a master of deduction, having found out Nona's hiding spot using his intellect and the clues presented to him. He is also very observant, having noticed that Cat is dumber than Gibby himself.
They were enemies at first since Nevel was always trying to sabotage iCarly, but when Dice was kidnapped by Nora, Sam had no choice but to turn to Nevel for help.
Nevel found Cat a "pretty redhead" but soon found her annoying as she called him "Nibbles" and made a dumb conclusion about a donkey eating a hamburger because of the donkey sauce. He then remarked that she made Gibby look like a genius.
They were enemies at first since Nevel was always trying to sabotage iCarly, but after Dice was saved from Nora, the two of them went to have dinner together, along with Gibby's head replica.
Nevel: Okay, this girl makes Gibby seem like a genius.
Nevel: Ooh! But we're splitting the check three ways.
Nevel: You'll rue this day, you'll rue it ! Oh wait, I keep forgetting I'm supposed to be helping you
- His middle name, Amadeus, is also the middle name of Butler Torso.
- Even though he was an antagonist for every of his iCarly appearances except two ("iChristmas" and "iPity the Nevel"), he doesn't have an antagonist role in Sam & Cat.
