The Company has a second Board of Directors.
Angela and Arthur Petrelli, Maury Parkman, Linderman, and the others were just a front. Even though their Company is now destroyed, a second Cabal works behind the scenes, pushing things to create opportunities for World Domination. The members of this Cabal are:
 * Tim Kring, because you know that would make sense.
 * Haruhi Suzumiya, because it's obligatory.
 * Doctor Doom, because his brilliant mind would not allow him to miss this opportunity.
 * Mr Muggles, because everyone else thinks so.
 * Sweeney Todd, because why not?
 * Fred the Manniquin, because he already betrayed Will Smith...
 * Adam Monroe, because it was mentioned in the show.
 * Zach from Season 1, because someone needed to spy on Claire...
 * Dr. Phil, because haven't you seen that photo of him pointing his finger at the camera, Sylar-style? Obvious proof that he eats brains!
 * Edward Cullen, because everyone needs an Ultimate Evil.
 * Molly Walker, because she's too cute to not be suspicious.
 * Albert Wesker, because Umbrella is staffed by imbeciles.
