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 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.
In the fourth series episode "Manic Organic" Mortimer attempts to sell Anil Toxic Waste.

But this backfires when it causes the vegetables to grow rapidly and large and Anil eventually decides to join them and help sell their products in his cafe. Unfortunately the mutated vegetables causes rapid hair and beard growth, but Mortimer sells them cheap razors which they sell to the customers who buy the veg.
Mortimer also later worked with "Sinister and sadistic scientists" to capture Mr. Stephen's clone for experimentation, but tricked Basil & co into thinking he was helping them. Eventually, after his etrayal was revealed, the scientists kept Mortimer for animal testing.
