If this is your first modification with costumes in an own category, 
so it's no problem to install the datas "category.ini" in your destination folder
"The Movies\Data\costume"
But if you already have some modded costumes in own categories, so don't overwrite
your "category.ini" datas, otherwise your former modded costumes wouldn't work anymore.
Just open your excisting data "category.ini" and add the lines:
[category_masters_of_the_universe]
        cat = category_masters_of_the_universe
Then save your changings.
The "data" folder must be installed in your "The Movies" folder as usual.

The "He-Man" costume was created by FraasMovies,
the "Teela" and the "Roboto" costumes were created by Tonda

Use it on your own risk!

Have a lot of fun with your "Masters of the Universe"!
