Hero Games/DOJ owns the rights to CLOWN. I have permission from Jason to incorporate them, along with another 4th edition villain, into Villain Codex III. It will be similar to my use of Terror Inc. in VC II, except that Heroic Publication owns their rights and allowed me to use them.
Will be using information from the 4th edition material, making some changes and additions.
IMPs on the other hand is a group I created that has a similar look to their membership. Their use and philosophy will be completely different.
