Nasty Nicola

Nicola, under the nickname of Nasty Nicola is a new girl who joined Horrid Henry's class in Horrid Henry and the New Best Friend. She is a manipulative girl who tries to get Henry into trouble by telling him to hide behind the bins when playing hide and seek and leaving him at the end of break, picking one of Miss Oddbod's prized petunias and telling her that Henry told her to. She also took Henry's lunchbox and put other people's food in it to make it look like he stole it. She gets expelled at the end of Horrid Henry and the New Best Friend for her behaviour.

She makes a cameo appearance in Horrid Henry Meets BB Silver where she is seen in the queue waiting for BB Silver to sign her book. She is called Ashen Annabel in this episode.

By Series 4, she is back in school as her suspension most likely ended. She still appears to be mean. She has spoken a few times and it's mostly to make negative comments about people and say nasty things, hence her name.
