The term 'David Copperfield Villain' refers to two characters from the Charles Dickens novel David Copperfield. The first character is Uriah Heep, a villainous clerk who works for Mr. Wickfield and schemes to take over his business. He is described as a 'lank, bony, yellow-faced man' with a 'low, creeping' manner. The second character is Uriah Heep's alter ego, a nine-letter pseudonym he uses to conceal his true identity. Heep is a cunning and manipulative character who uses his false identity to gain power and influence. He is ultimately exposed and brought to justice by David Copperfield.
