Dino Piranha
	Location: Good Egg Galaxy - Dino Piranha Melty Molten Galaxy - Fiery Dino Piranha How to defeat: Notice the ball at the end of the dino's tail. Punch it to ram it into its egg, cracking it. It will start to chase after you. You must get behind it and repeat this process three times to defeat it. For the Fiery variation, do the same, but only when its tail is not on fire.
King Kaliente
	Location: Good Egg Galaxy - King Kaliente's Battle Fleet Bowser Jr.'s Lava Reactor - King Kaliente's Spicy Return How to defeat: Avoid the rocks he spits out. When he spits out a green coconut, perform a spin attack to rebound it back at him. Repeat three times to defeat him.
Bugaboom
	Location: Honeyhive Galaxy - Big Bad Bugaboom How to defeat: Get on top of the giant insect and perform a ground pound (A+Z). Three hits are needed to defeat the boss.
Megalegs
	Location: Bowser Jr.'s Robot Reactor - Megalegs' Moon How to defeat: Climb up any one of its legs. Once on the upper portion, lure Bullet Bills towards the flashing red light at the top.
Kamella
	Location: Space Junk Galaxy - Airship Attack Deep Dark Galaxy - The Underground Ghost Ship How to defeat: Avoid the fireballs she tosses. When she tosses a green shell, perform a spin attack to pick up the shell and perform another spin to toss it at her. Three shells and she's dead.
Tarantox
	Location: Space Junk Galaxy - Tarantox's Tangled Web How to defeat: Use the Sling Pods to catapult yourself onto the spider's green and red spots. Burst all of them to defeat it.
Topmaster
	Location: Battlerock Galaxy - Topmaniac and the Topman Tribe Dreadnought Galaxy - Revenge of the Topman Tribe How to defeat: Jump on the Topman, while dodging the spikes. Then perform a spin attack.
Bouldergeist
	Location: Ghostly Galaxy - Beware of Bouldergeist How to defeat: Avoid the rocks it tosses and the spikes that raise out of the platform. Dark rocks contain Bomb Boos, which you must spin so that they explode on the boss. Three spins and the boss reassembles itself. Three more ends the battle.
Major Burrows
	Location: Gusty Garden - Dirty Tricks of Major Burrows How to defeat: Run between Major Burrows and the rabbit. When Burrows rises above the surface, perform a ground pound and spin into him. Repeat twice to defeat him.
Baron Brrr
	Location: Freezeflame Galaxy - The Frozen Peak of Baron Brrr How to defeat: Avoid his shock waves and spin into him. He turns small. Spin into him again to score a hit. Three hits and he's defeated. In short, he is defeated the same way as Lava and Ice Bubbles, except he has 3 hit points.
Bowser Jr,
	Location: Bowser Jr.'s Airship Armada - sinking the Airships How to defeat: Use the same strategy as for Kamella: stomp Koopas to obtain shells, and spin the Remote to toss them into his airship.
Bowser
	Location: Bowser's Star Reactor - The Fiery Stronghold Bowser's Dark Matter Reactor - Darkness on the Horizon Bowser's Galaxy Reactor - The Fate of the Universe How to defeat: Dodge his shockwaves and fireballs. Stand on top of a blue circle and lure Bowser so that he crashes into it. Once his tail is on fire, spin into him. He'll lose control and spin around the reactor very fast. Spin into him again. Three hits and he's defeated. The final battle is basically an extension of the regular battle, except spread out into three phases. In the first phase, spin into Bowser when he's in a boulder. In the second phase, spin into the green plants so they hit him. The final phase is the same.
