The crowd is the bunch of figures that appear 2D, they appear in battles especially ones of really powerful creatures. They love one character but they hate another, the one they care about, wins. When the bad guy is winning they say boo! And cause bad luck and discomfort for the bad guy, but when the good guy is winning they cheer causing the good guy to have stronger hits and healing. Even if the bad guy wins, they don't kill the bad one, they heal the good guy.
