I beat all of the characters in the maze, but a door never showed up for me to fight Tabuu. Is there something else I need to do?

Did you check the middle of the map. Look there, then go there.
Also, you press up in the middle of that place.

THere's a large door in the background of one of the rooms. In front of it are statues of the characters and bosses you still need to beat. When all of them are gone, enter the room and push up in front of the door.

Look in the background, if there's a trophy in the background, you did not finish.
Once there is no one else, go in the room, then press up.
