Perius is the default model, but you can create pretty much any male Monteblanc ever, given how alike they all look. Mostly this thing is an excuse for pointy Veran jackets. Which come equipped with a Randomise button.
Extra noses and body/hair/clothing colours have been added for OC customisation purposes, if you've got an OC with a thing for pointy jackets.
You can give him just the lower half of a jacket because I don't know how to rig it so you can only have a lower half if you have an upper half. Ignore this and pretend I programmed it better.
