As guessed by their supervillain names, they each have themed colours, Alex being purple and Emily being red. Those colours were chosen as we wanted them to look stereotypically evil compared to Rebecca whose colour is green.
Both Alex and Emily have decided to start making their own masks out of card and decorating them with their assigned colours. Luckily they both have capes at home and Alex has even got 2 wigs, one red, one purple, so that her and Emily can look even more like the part.
For the bullying parts, they will probably just be dressed in black and leather etc.
