Doctor Doom mask inspiration from here; all costumes are DIY except Spidey (if you know where to find a Firestar costume, I'd really like to hear about it...) Mom is Doctor Doom (mom's are always the bad guy), and Ice man glows in the dark.
The cocker spaniel is a stand in for Ms. Lion, for those fans of the show out there (both of you).
Thanks for checking it out! I'll try to answer any questions in the comments (and please bear with me as this is my first 'ible)
