Green Lantern arrived in Star City and found Batman and Green Arrow just in time to catch the end of their conversation.

"And I'm supposed to do… what, exactly, against this thing?"

"I don't know yet, but the more people we can gather, the better we'll be able to fight it."

Batman noticed Hal's arrival.

"Any luck?"

"No. He wasn't there. We could try Blue Beetle in Hub City or I could contact the corps."

"Maybe that could – wait, no time, it's here!"

The android was flying straight at them. Green Lantern grabbed it with his ring, spun it around, and threw it before it could break free, the delay in the robot's progression allowed him to pick up the other two heroes and start flying away.

"I have an idea, if you can get us to Gotham," said Batman.

"Working on it," Green Lantern responded.

While the android had flash's speed, it could not employ it while in flight. As such, its top speed in the air was that of Superman. While it was dangerous to go much faster while in a planet's gravitational pull for a Green Lantern, Hal was still able to reach Gotham City before the robot.

"Go for those hills over there. I have a plan, but I'll need some time," said Batman.

"I understand. I'll hold this thing off. Just make it quick."

"What's the plan?" Green Arrow asked.

"I'll explain later."

Hal dropped the two non-powered heroes near a boulder, which revealed itself to be fake as it slid aside for Batman, revealing a tunnel within.

Green lantern turned to face the android.

"Bring it on."

Batman and Green Arrow had followed the tunnel to the Batcave, and were preparing for the android's arrival.

"Lantern won't hold that thing for long, so we'll need to work fast. Help me get these chunks of wood into position and get on top of that outcropping.

"Uhh… Batman? Why are we arranging blocks of wood in a circle?"

"Not now, Arrow."

"Alright, alright. Got it."

They heard an explosion from the tunnel.

"It's coming, get into position!"

Green Lantern was hurled past them, landing next to the Bat-computer, unconscious. The robot stepped into the cave, entering the circle of wood. Batman took a small, glowing, green object out of his utility belt and tossed it at the android's feet. It faltered but began to advance again. Batman pulled out a lighter, and tossed it onto the wood, lighting it on fire. The robot stumbled and fell to its knees. Batman charged it, punching it in the face. It threw him, and he flew across the cave, landing near the Batmobile. Green Arrow let an arrow fly, hitting the android in the temple.

"Gotcha."

The arrow released an EMP, and the robot fell over, limp. Arrow jumped down next to it.

"Not so tough now, are ya?"

As if in response, the android grabbed him by the ankle and pulled him down, raising its fist. Green Arrow rolled to the side.

"Alright, how about this?"

He drew another EMP arrow, and stabbed it directly in the robot's face. It detonated, shutting the android down.

"Stay down this time."

Batman ran through the fire and removed the robot's memory core.

"Now to find the rest of the League."

Author's note: I almost regret starting with this story arc. I wanted to start by doing something that I'm not going to spoil just yet, but I'd also really like to start using some other characters. Admittedly, Bats and GL are my favorite and second favorite DC Heroes, respectively, but it'll be nice to free up some more characters to use.
