Ben had barely gotten a handle on Eonblade when the Crossfire Collective launched their full-scale attack on Earth. The skies above the city were filled with alien warships, their dark silhouettes blotting out the sun. Explosions shook the ground as the invasion began.

Gwen (frantically scrolling through her spellbook): "We need to slow them down! I'll handle the aerial assault—Ben, take the ground forces!"

Ben slammed the Omnitrix, transforming into Humungousaur, his massive dinosaur-like form towering over the streets. He charged headfirst into the enemy forces, throwing tanks and crushing alien walkers underfoot.

Humungousaur (laughing as he hurls a tank across the battlefield): "This never gets old!"

But the real challenge came when Kaelak, the Crossfire Collective's most feared warrior, dropped from the skies, landing in front of Ben with a thunderous crash.

Kaelak: "Tennyson! You think you can stop the Collective with mere tricks?"

Ben grinned and hit the Omnitrix again, transforming into Terraquake. The ground beneath them rumbled as he summoned massive chunks of earth and hurled them at Kaelak.

Terraquake (snarling): "Let's see how you handle an earthquake!"

The two titans clashed, sending shockwaves across the city. Buildings trembled and debris flew as they traded devastating blows. But despite Terraquake's power, Kaelak proved to be a formidable foe, matching Ben's strength with raw fury.

Kaelak (growling as he blocks a punch): "Your aliens are no match for the Collective!"
