you have to unlock the great maze. then search for bosses and characters around the maze and beat all of them. after that go to the middle of the maze and in the background there will be a giant door. it opens up and then you fight tabuu. if you go there before you've beaten all of the bosses and characters it will show you what bosses you havent beaten yet as trophies.
None of the bosses including tabuu can be played.
If you mean playing as Tabuu you cant so you cant unlock strictly speaking.
go though all shadow doors then do to the door that leads to tabu
well when he does the rings you need to sheild and press down a bunch of times to dodge it.
i would say out of the non play able characters it is tabu out of the playable bowser
Yes- hit him with a trophy base after he is at low health. "Very easy" mode is most productive.
just attack him
Yes you can. That is how you beat the adventure mode.
first time YES same with second, but after a while it gets kinda easy, until you try it on intense difficulty.
Yes he is. He appears as the final boss in the game
