The police managed to hold off as long as they could, but their efforts at slowing the robot's advance would have been as effective as trying to move a mountain for all the good they did. Still, the Chief of police had just enough time to communicate the situation to the dispatcher, right before his police car was turned onto its side and the signal cut off.

Back in the station, the dispatcher stared at her phone wide-eyed and pale, the sounds of gunshots and shouting still ringing in her ears. Her thoughts raced as she tried to think of which department to call, what kind of force would be needed to deal with a threat like this. Her eyes slid across the room restlessly and landed on a poster on the wall of a tower on an island, shaped like a letter T-

Back-up arrived, but a little too late. By the time the newly appointed Teen Titans arrived, there wasn't anyone left to assist. The cop cars were strewn across the construction site like discarded toys. The heroes would be on their own for this fight.

Like the previous encounter, the robot retreated to its pit after its rampage of sudden carnage and was currently patrolling the perimeter of the pit tirelessly. The lights on its body had shifted back to an almost calming shade of blue.

It didn't seem to notice their presence. Either that, or it just didn't really care. Not yet, at least. It didn't react to the sudden shroud of darkness that fell over the area, or the small creature that came to investigate it. For now, all it did was pace in circles, slowly but purposefully, over and over.
