But the worst one would have to be the Boomsday Machine from Super Mario Galaxy 2. That one is sooooo hard. Worse yet, the Prankster Comet for that one is a DAREDEVIL RUN!!! It was impossible for me to beat that boss without losing health!
i dont remember which game the boss i hated was in. it might of been new super mario bros. he was a guy that stood on this platform throwing bombs at you. and you had to catch one throw it on his platform and hurt him three times.
it was easy when you could actually catch them without falling in a hole or being hit by a second bomb he'd throw and you never seen coming. i that is the only mario boss i ever struggled with.
