Cousin Mortimer

"Ha Ha Ha Ha Bang Bang"

- Mortimer's catchphrase

Mortimer Trouble Brush also known as Cousin Mortimer is the cousin of Basil Brush and a recurring villain in CBBC sitcom The Basil Brush Show. He is voiced by Don Austen.

In his first appearance in the series, Mortimer pretended to be kind and helpful to locals, but this was to earn their trust and was secretly stealing from them and getting Basil into trouble. He was later revealed to have been in prison, but got released, but still caused havoc.

In the third series, Mortimer and Basil had to get along for 24 hours without fighting or arguing. However, they over-wound the wind-up clock and started fighting a minute too early. He later appeared at Basil's wedding to Kelly Foxwell, but in the end, Kelly liked Mortimer more.
