Mwah ha ha! Now what do we have here? Why, if it isn't my old pal Luigi ! Or is it Baby Luigi? I can't tell the difference. Hey, remember that time you trapped me in a painting for all eternity? Good times. But guess what? I GOT OUT! And now I'm painting the town RED! Yes, it was I who broke the Dark Moon! This power-enhancing jeweled crown of mine made it easy. And now that all the ghosts of Evershade Valley are under my control, it's time to take my rightful place as supreme ruler of your world! You, that annoying scientist, and all your friends will look great hanging from the wall of my throne room!

Look at this little scrap. Friend of yours, is he? Well, if you like your friend, you better stop attacking me! Now, don't go thinking it's OK to attack my little minion either. Who knows what could happen if he dropped your little friend there... You got that?

~ Portrait Bio
Background King Boo is the leader of the Boos and ghosts, ruler of the Paranormal Dimension, the main antagonist of the Luigi's Mansion series, and the arch-nemesis of Luigi. He is also an ally of Bowser, who has aided him in his various schemes. He is more than capable of devising and enacting villainous plans by himself, including his capture and imprisonment of Mario. Although not the biggest Boo, King Boo has abilities that far surpass that of the average ghost; he wields a number of impressive magical abilities, including the ability to materialize objects. King Boo's magical power is directly proportional to the number of Boos in his vicinity.
