Formely an angel like Kayle and Morgana. However Mordred took a pact from the powerful demon known as Hephastopheles, and thus became a Nephilim (half-angel, half demon). Since Mordred was unaware of his angelic past and doesn't know his parent, he look more like a demon.

The title, "Wicked King" was formerly known as "Demon King". But since RiotRaven did state that devil doesn't exist in lol and Kayle/Morgana isn't referred as an angel (even though Morgana got "Fallen Angel" as her title), I decided to call demons as "wicked". Thus Mordred became known as "The Wicked King" since no other wicked could beat him.
