Ludicrous Malfoy was the father of Draco Malfoy and a servent of Lord Voldy-Mort. His actual name is Lucius Malfoy, but no-one wants to call him that so they all call him Ludicrous Malfoy instead. He has a habit of being really dicky to people for no reason and then getting insulted if they talk back to him. He does almost nothing for the whole course of the Wizarding War, except making failed attempts on Harry Potter's life, and he ended up fleeing the Battle of Hogwarts with his wife and son.
