At the heart of the Nebula, the Temple of Infinity loomed, a colossal structure made of glowing, ancient stone. But before they could approach, they were intercepted by the Eternal Guardians—giant, armored beings tasked with protecting the Temple.

Kevin (charging his gauntlets): "Let me guess—they're not here to give us a warm welcome?"

Ben transformed into Four Arms, his towering red alien form perfect for smashing through the Guardians' defenses. With a roar, he charged into battle, trading punches with the colossal beings, their metallic armor clashing with his brute strength.

Four Arms (grinning as he delivers a powerful punch): "I've taken down bigger!"

Gwen, using her magic to deflect energy blasts, called out, "Ben, we need to find the entrance while you hold them off!"

Kevin nodded, joining the fight with his energy blasts. "Leave it to us. We'll crack this temple wide open!"

But just as the team seemed to gain the upper hand, the ground beneath them rumbled. A voice echoed through the air, filled with power and malice.

"So, the bearer of the Omnitrix has arrived."

From the shadows emerged Ignis, the leader of the Eternal Flame. His body radiated with fiery energy, his molten eyes locked onto Ben.
