User blog:Flamephoenix/Identify Hallowinx Episode Characters

I need help to identify the references in the Hallowinx episode from Season 2 because I don't know enough about pop culture.

Can the Wiki users help me identify who these characters are disguised as? I do not need generic answers as "a superhero" or "a skeleton," I need to know which specific character from another franchise the Mitzi's guests were disguised as.
