Issue #86: Nolan fights Allen to prevent him from releasing the Scourge Virus onto Earth, as there is a 50/50 chance it will kill all the humans since they are so genetically similar to Viltrumites. Allen sees this as the only way to stop the Viltrumites once and for all; sacrifice 6 billion to save 6 trillion and all. Nolan gets the crap beat out of him until Oliver shows up and breaks up the fight. Both Nolan and Allen give Oliver their side of the story, and Oliver decides to side with Allen. Nolan gets away and tells Debbie they need to get back to Earth and warn Mark since Allen and Oliver are already on their way there.
Issue #87: After Invincible and Dinosaurus defeat Omnipotus, the Guardians of the Globe attempt to arrest them both, but they get away. Mark then flies into space and meets Allen and Oliver, who tell him their plan. Mark doesn't like it at all and tries to stop them, but like Nolan, he gets the crap beat out of him. But just before the final blow is struck, Thragg, the leader of the Villtrumites and the most powerful one of them all, steps in and rescues Mark and then promises to stand with him to stop Allen. So in the next issue we're going to have Invincible and Thragg vs Oliver and Allen. Can't wait. You're welcome.
