Tyrant attempts mind control over Morg, a devoted herald of Galactus. Will Morg find himself with a new master…and the Power Cosmic? Ganymede agrees to help Thanos in his takedown of Tyrant. But Jack of Hearts and Legacy have tracked down Ganymede- straight into Tyrant’s fortress!

Tyrant attempts to further persuade Morg into serving him, but Morg will only serve Galactus. He begins to peel back the layers of Morg's mind and learns his origin, but Morg will still only serve Galactus, who he believes is the stronger of the two.

Meanwhile, Ganymede starts to willingly cooperate with Thanos when she learns he plans to take on Tyrant. They engage Tyrant's Fortress and easily dispatch his robotic guards. Tyrant then implants Morg with a control device and sets him loose on them.

When Legacy and Jack of Hearts arrive they create a massive explosion. This explosion frees Morg of his control device. He decides to leave and return to his true master as opposed to the vengeance he wishes to have on Terrax.

Now they all face a bigger threat - Tyrant.
