Masquerade

My mod/plugin allows you to disguise yourself as your friends or enemies by beheading them with a sword or axe and wearing their heads on your own. You will look like the person whose head you are wearing, and you will have their cape. Your name will be the same as the person's in the tab, chat, achievements and on every screen that I know of. You can also hide your identity by using an invisibility potion.

If you want to disguise yourself you should:

1. Kill a player you want to disguise as with a sword/axe named as Beheader / The Beheader.
2. Pick up their head.
3. Put their head in "Helmet" slot.
4. ??? = Profit.
   Head removes itself from "Helmet" slot so you can place helmet or any item into the now-available slot.
   If you want to remove disguise you can use command /masquerade remove

If you want to hide yourself

1. Brew an Invisibility Potion.
2. Use it. And don't worry about potion particles, there are none.
3. ??? = Profit.
