You know since Harvey Birdman is in Villainous does that also mean that Adult Swim villains would also be in the Black Hat Organization. I mean that means The Monarch, Dr.Girlfriend, and the other Team Venture villains would be there as well.
There is also the fact that Frisky Dingo would be on there as well, which fits with Villainous themes of focusing on the bad guys while the heroes in the world are not that heroic.
And seriously, I know the series focused on the more family friendly properties but you would bet your ass that Black Hat is expanded into those family unfriendly ones as well, especially since they are not restricted by a family friendly rating.
