Up next is another lesson that was requested by a few people. I know this character is old, but he is still a classic. Today, we will learn how to draw King Boo, step by step. For all you Mario Bros. enthusiast you should recognize this face as being the main antagonist in all the Luigi's Mansion video game series. King Boos is the leader of all the Boos just as Bowser is king of the Koopas. Drawing King Boo isn't going to be difficult at all. He is just a ghost with some gnarly teeth with a crown. I shall return in a few with some other tuts so stay tuned in to see what they are.
