After the final victory, Ben stood alone on a cliff overlooking the horizon. The sun was setting, casting a warm glow on the destroyed battlefield. Gwen and Kevin approached him from behind, but Ben's mind was elsewhere.

"You okay?" Gwen asked gently.

Ben nodded, though he remained quiet for a moment. Finally, he glanced at the Omnitrix on his wrist.

"It never stops, does it?" Ben murmured. "Every time I think I've done enough, something else comes along. But I can't stop now... not when there's more at stake."

Kevin smirked. "That's the price of being a hero, Tennyson. You ready for the next adventure?"

Ben looked at them both and smiled. "Always."
