I like shrowser because he is the smartest boss of the series. He does'nt let you attack. If it wasn't for Beeg princess shroob, It would go on until mario and luigi die. the babies will just sleep.

personally i thought shiny robobowser was kinda cool but my favorite would have to be dark bowser

My opinion on each of the bosses: Bowletta: Peachette is bad, but this was worse. The Devs were probably drunk when they came up with this. Shrowser: The one everyone forgets about. It's really lacklustre compared to the elder shroob fight right before it and feels like a last minute addition. Dark Bowser: Bowser Vs. Bowser action is cool, and I like the aesthetic and music best out of all the bosses. The button mashing is the only thing that ruins it for me, the only way I can beat it is with both X and y at the same time. Dreamy Bowser: He looks cool, but the fight itself sucks. His healing move is really overpowered, I had to use easy mode JUST because I couldn't deal enough damage to beat him. Also, if you don't have enough taunt balls it becomes really annoying as there's no other way to attack background enemies. Shiny RoboBowser: the armour is pretty awesome looking, but it's not a perfect boss fight. Also, this is the only one where bowser has full control and isn't possessed or something

True about Shiny RoboBowser. I like Dark Bowser best because it's Bowser vs Bowser and Mario & Luigi vs Dark Star Core. Bowletta's not all bad though because she inhales us and we get to do the Cackletta's Soul battle, which is hard but feels very satisfying when you finally complete it! Shrowser was kinda easy compared to Elder Princess Shroob. I agree with Dimentio24 about Dreamy Bowser. He looks the part, but isn't a good fight.
