In the figure, in the fake version, in the left hand holding the cape, the position of the stars changes completely, showing a 2-2-1 format. The paint and shape of the mouth is another important detail. On the box you can see the width of the edge at the top right, and also notable differences in the fonts around the entire box, for example at the bottom, regarding the warning message.
