White Knight told Rex and Ben that they must go there in search of Alpha, but Rex replied that this city has a force shield. However, White Knight informs them that this is no longer the case. When White Knight, Ben, and Rex arrive at the city, the city's shield is largely destroyed, allowing them to enter.
When they reach the inside of the city, it looks the same, but without the EVOs. They find Alpha absorbing the Bug Jar's nanites. When Alpha evolves into Alpha-Omega, it destroys more buildings on the site with more of the city being destroyed during the battle.
