The Hall of Villains

 It is a room where the characters of the day of the dead are among them: master chen, morro, samukai, kozu, pythor, crypthor and yang with Cole, Lloyd, Nia, Zane, Jay, Kai

Why did I build it? I noticed they are releasing some new sets from previous seasons and none from All Souls Day.

Why do I think it would make a great LEGO set? Because it would be a reminder of everything that has happened in all the past seasons.
