As the battle raged on, Ben realized that brute force alone wasn't enough. Kaelak was too strong, and the Crossfire Collective's forces were overwhelming Earth's defenses. That's when Gwen and Kevin stepped in, forming a plan.

Gwen (casting a shield around Ben and Kevin): "Ben, we need to work together. The Omnitrix has more power than we realize. We need to find its true potential."

Ben, still bruised from his battle with Kaelak, nodded. "Alright, but what's the plan?"

Gwen pointed to the symbol that had appeared earlier on the Omnitrix. "That symbol—it's not just unlocking new aliens. It's connected to something bigger."

Kevin, gripping his plasma gauntlets, added, "We need to channel its energy into something... something stronger."

The three friends stood side by side as Gwen used her magic to amplify the power of the Omnitrix. Ben hit the dial once more, and in an explosion of green light, a new form emerged—Unison. This alien was unlike anything Ben had transformed into before—taller, more imposing, with glowing patterns across his body that pulsed with the energy of all the aliens combined.

Unison (his voice echoing with power): "I can feel it... all their strength. Let's end this!"

With Gwen and Kevin's combined support, Unison unleashed a massive wave of energy, turning the tide of the battle. Alien warships were knocked out of the sky, and Kaelak was forced to his knees, defeated.
