What is the literary term when a character's name matches one of his key characteristics?

Question

For example, Mrs. Malaprop in Great Expectations. Or if some horny dude in a book was named "Randy"....I know there's a term for it....

Answer 1

Malapropism was named after Mrs. Malaprop - not the other way around.

Depending on how the story is constructed, this could be an allusion, a symbol, allegorical, metaphorical, etc.

Answer 2

Mrs. Malaprop was in Sheridan's "The Rivals" not in Great Expectations. Eponymous seems to be the nearest term I can think of for your question. Or perhaps Antonomasia.
