Nazca Lines' Secret Weapon

The secret weapon located in the Nazca Lines serves as a hidden tool of counterattack against the Xevian invasion. Archaeologists discovered this weapon just as the threat became more and more apparent, though their claims were initially dismissed; however, Agent Darkbootie later sees firsthand that the weapon exists, and the rest of the Swollen Eyeball Network find that it is powered by the four natural elements—fire, earth, water, and wind—which happen to be abundant in the target objects for both the alliance of heroes and Mr. D during the Search for the Sacred Elements.

When activated, the weapon is rumored to bring about a total eradication of all Xevian forces, using the four elements; naturally, GAMP intends to prevent this from happening, and so orders his fleet and army to find this weapon and destroy it. However, seeing as it appears to be indestructable and could inadvertently be triggered, the Xevians instead establish safeguards and countless bases and towers in the area, so that the weapon cannot be found or used. Tak herself sees to the demise of Darkbootie and the rest of the Network so that they fail to spread word of this weapon to the alliance of heroes; on the other hand, Zim has already found out about it, and later informs everyone else. The threat of activation now increases dramatically, seeing as the group also possesses the chaos emeralds, which GAMP realizes will further power the destructive capabilities of the secret weapon, should they come in contact.

For all of Tak's efforts to keep the sacred elements and chaos emeralds away from the weapon, ultimately they are for naught; in the end, the ensuing battles taking place in the Nazca Lines lead to elements and emeralds' energy being absorbed—and thus, the Activation of the Secret Weapon takes place. The result is a giant beam that first generates a barrier: one that encases the entire area and traps the Xevians where they stand, before later expanding to shield the entire planet from further invasions; at the same time, the powerful surge of energy pulls in countless Xevian structures and vessels (as well as the defeated Mr. D) and destroys them—though the Andor Genesis and its accompanying Destroyers just barely escape the forming barrier, courtesy of Tak's quick thinking. Doom befalls the rest of the local Xevians, however, for as soon as the barrier is in place and the alliance of heroes have transported themselves away, thanks to Calvin using Dib's watch, the weapon then uses the elements and emeralds to generate massive surges of elemental disasters, which completely obliterate the Xevians and their base of operations, causing their invasion to grind to a halt.

The weapon's activation is what signals Operation Solvalou to at last make its final effort to defeat GAMP, and prompts them to travel to the planet Xevious to do so—thus, the activation itself proves to be a pivotal event in the "Dimension" saga.
