The Bad Guy Network is how people of the not-good persuasion contact one another - it's how the Henchmen find their bosses and how the bosses find Minions. At any time you can contact anyone through the Network

Evil Geniuses are free to interact with one another in RP or in thread (depending on how secret your plans are). If you want to join forces to bring down a stronger genius, or backstab someone, you can do so. Or maybe to smack JUSTICE around.

Maybe you just want to contact another Genius to taunt them with your superior monologuing skills, and to let them know that your Master Plan is superior to their mess.

You can also raid another evil geniuses Lair if you are feeling like a meanie.
