King boo mmwii
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 its OK to attack my little minion, either. Who knows what could happen if he dropped your little friend there... YOU GOT THAT?

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!"
~ King Boo to Luigi


King Boo is the leader of the Boos and the main antagonist of the Luigi's Mansion series and is the arch-enemy 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 and 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.

    • Thanks for this Question: can Luigi suck up non ghosts. He can in smash but that’s uncanon.
    • yes in M&L SS Luigi could suck up E.Gadd, and is also capable of sucking up small animals and the like (gold,pearls, and other materials).
