Bosses

 * Napoleon Knight (Recurring Boss of Worlds 1, 3, 5, and 7): The hot-tempered knight of the Hot-Cold Kingdom, he specializes in wielding a battle axe. His attack strategy involves attempting to ram into Luigi while swinging his weapon. Sometimes, he jumps and whirls the axe around himself to protect himself. However, 5 stomps take him down. With each encounter, he gets faster. By World 5, he throws mini axes like Hammer Bros. enemies and at World 7, he uses 2 axes.
 * Princess Onyx (Recurring Boss of Worlds 2, 4, 6, and 7): The devious princess of the Hot-Cold Kingdom, she specializes in dark magic. Her attack strategy involves teleporting and firing blasts towards Luigi. 5 stomps take her down, but with each encounter, her intellect lets her change strategies from using spread shots in World 3, using homing shots in World 5, and summoning a clone Luigi in World 7.
 * Foreman Spike (Boss of World 1): Mario's old rival. He was hired to destroy a part of the land to build a base under orders from an anonymous client. He attacks by riding an excavator which throws bricks. Occasionally, the machine throws a blue brick, which can be thrown back at him. The foreman must be hit 3 times.
 * Flame Serpent (Boss of World 2): A skeletal snake that's alight on fire. The monster never finds satisfaction in the current heat. It launches triple shots and burning rocks. Sometimes, it spits out a regular rock, which can be thrown back at it 3 times. However, the head is the only weak spot.
 * Powerful Porcupuffer (Boss of World 3): A raging Porcupuffer related to Big Bertha. This giant fish seeks vengeance on the one that took his sister down. He fights the same way as Big Bertha did, but occasionally, he spits out bubbles that can trap Luigi inside.
 * The false Mario (Boss of World 4): A faker created by the masterminds. This copy jumps and shoots fireballs. Each time he's stomped, he runs with Starman-like invincibility for 10 seconds. It takes 5 stomps to defeat him.
 * Sumo Warrior (Boss of World 5)
 * Traitor of the Yoshi clan (Boss of World 6)
 * The Menacing Machine (Boss of World 7)
