Plot
On a distant planet, a war is about to start between red beings and blue beings. Ben, Gwen and Kevin travel with Ship to this distant planet. On the Plumber trackers, they get a message from a little girl named Probity to stop the war. When they arrive, Ben tries to talk the red aliens into not fighting, and then Kevin meets up with an old friend, Argit and they start selling weapons to both sides. Ben's influencing doesn't work and the red soldiers attack. Ben turns into a "new alien", Lodestar. (Ben transformed into Lodestar, off-screen, at the end of War of the Worlds: Part 2) An alien with magnetic powers and fights back. The red team backs away and retreats.

Ben's various attempts at getting the two sides to form a peace treaty fail miserably. The day of the war comes and Gwen and Probity watch in disgust. Ben turns into Way Big and goes in between the two armies. He talks them into not fighting, but Way Big accidentally knocks down the statue of their sage and they declare war on Ben instead of each other. Ben, Gwen, and Kevin are forced to retreat and leave the two sides to their war. Kevin is forced to leave Argit and his loot.

In the end, Probity records a message to Ben saying that now she has no home, has to work double time to pay for school, and hates him alongside the war. She then discovers Kevin's loot which makes her happy.
