The journey to Zyrrak 9 was long and treacherous. As the Rustbucket entered the Shattered Constellation, the stars themselves seemed broken, their light scattered and twisted in unnatural patterns.

Gwen (whispering): "It's like this whole region of space is... decaying."

Ben sat in the pilot seat, his eyes fixed on the planet looming ahead. Zyrrak 9 was a barren world, its surface dotted with the remnants of ancient civilizations, long forgotten and left to the mercy of the cosmos.

As they descended, the atmosphere became thick with dust, and the ruins of towering structures became visible beneath them. Strange energy readings pulsed from beneath the surface, echoing through the Omnitrix.

Kevin (loading up his plasma rifle): "Whatever's down there better not make us regret this."

The team landed near a massive temple-like structure, its walls covered in inscriptions that glowed with a faint, eerie light. Ben activated the Omnitrix, its light struggling to maintain a steady glow.

Ben (whispering to himself): "Let's see what we're dealing with."

He transformed into Terradrone, a new alien form—massive, with a rocky, insectoid exoskeleton and the ability to burrow through the earth with ease. Ben dug into the ground, leading the team underground, following the strange energy signals.

The deeper they went, the more the air buzzed with cosmic energy. They eventually arrived at a vast underground chamber, filled with enormous crystalline pillars. At the center of the chamber stood a stone pedestal, and atop it was a swirling orb of energy—The Cosmic Core.

Gwen (eyes wide): "That must be the source of the disturbance."

Before they could react, the ground trembled. From the shadows, a towering figure emerged—an ancient alien warrior covered in metallic armor, his eyes glowing with the same energy as the Core.

Warrior (his voice deep and resonant): "I am Zarthon, last of the Cruxalans, protectors of the Cosmic Balance. You, bearer of the Omnitrix, have disturbed the balance of the universe."

Ben (transforming back to human form): "We didn't come here to fight. We came because the Omnitrix is in danger."

Zarthon (gripping his weapon): "The Omnitrix itself has upset the balance. Its power was never meant to be unlocked. You must surrender it, or face the consequences."

Ben stepped forward, his voice steady. "The Omnitrix was meant to help people. We've saved entire worlds with it. I'm not giving it up."

Zarthon raised his massive staff, its tip crackling with energy. "Then you will face the Cosmic Judgment."
