The Galactic Usurper
King Boo appears as a boss in the The Galactic Usurper story mode.
King Boo has the ability to split into a mass of Boos and damage the players. The trick to defeat him is to turn your back to him. He will then approach you to attack. If you turn around, even during an attack (Ike’s down smash for example), he will turn invisible and transport himself to a different aerial of the stage.
Down Aerials such as Link’s, Pikachu’s, and Shulk’s, Down Smash’s like Dark Samus, Squirtle, and Mario and specials such as Zelda, Kirby, Yoshi, and Dixie King can hit King Boo.
The battle begins with King Boo separating himself and transform into a mass of Boos and will charge forward. Dodging, blocking, or attacking them will help you avoid their attacks. After a while, the Boos will regroup and transform back into King Boo. He will then teleport around the room. He will then start to spin. At this point, turn around and he will begin to approach you menacingly.
Once hit, he will spiral out if control and run into the right or left hand wall and burst into a whole bunch of Boos and will become stunned. Landing one hit on a Boo will cause it to vanish in a puff of smoke. Attacking more of them will cause the King Boo to decrease in size when he re-arranges himself. Keep on doing this until the last Boo disappears. King Boo will re-appear in full form but a lot more transparent than before. He then vanishes in a puff of smoke.
King Boo appears, spins in the air, and changes into a mass of smaller Boos. He charges towards the stage and smashes everyone in his way. It does 2% damage each hit and can hit between 20-25 times. He does 3 passes back and forth through the stage and then reforms himself back into King Boo.
Bowser is the main villain of the Super Mario Bros. franchise so when I went looking for viable bad guys, I couldn’t find any that were really good. However, King Boo played the part of end boss in the Luigi Mansion games so I decided to use him as the boss rep for the Super Mario Bros. Series.
