Damien Derek Trotter (born 3 February 1991)[1] is a fictional character in the BBC series Only Fools and Horses.
Del and Raquel chide Rodney for his mad obsessions and believe Damien to be a perfect angel, spoiling him frequently.
From the earliest ages, Damien shows signs of being a spoiled brat, such as throwing things at Rodney, throwing seeds on the floor, deliberately waking Uncle Albert up from a nap, placing Cassandra's birth control pills inside an urn containing Albert's ashes, urinating in a public swimming pool (from the top of the diving board), encouraging his father to physically fight someone at a funeral, and even hoping that his father might get sent to prison merely to fit in with his group of friends with imprisoned fathers.
Although Del and Raquel seemed to remain oblivious to Damien's bad behaviour when he was younger, they did gradually become stricter with him in the final episodes and Rodney frequently calls him or refers to him as "Rap Boy" due to the way he dresses and acts.
Cassandra shares Rodney's view that Damien is the Antichrist and like Rodney she is tormented by Damien (such as spying on her whilst she was showering and hiding her birth control pills in the urn containing Albert's ashes).
