Superman stood up in the containment cell, uncertain what he could do. Suddenly, Batman spoke.
"Clark, I have a lock pick in my boot. Can you reach it?"
Superman reached into Batman's boot, trying to find the lock pick. Without his X-ray vision, finding it proved difficult, but possible. Superman withdrew the lock pick, handing it to Batman, who proceeded to rapidly unlock his own restraints, before heading over to Wonder Woman and unlocking hers, restoring her Amazon powers.
The door opened, and a swarthy woman dressed in leather entered. Batman was sent stumbling back when she threw a bolt of lightning into him, blocked mostly by his insulated armour. Wonder Woman stepped forward, having claimed her whip. The woman faced Wonder Woman, sparks arcing across her fingers.
Storm attacked with a bolt of lightning, which Wonder Woman blocked with her wrist bracers. Wonder Woman then flashed forward, collecting Storm and smashing straight out of the helicarrier. The structural damage cut the power to the red UV lights, removing the imitated red sunlight, and allowing Superman's powers to restore.
Outside, Storm filled the sky with lightning bolts, while Wonder Woman struck the bolts aside with her whip and bracers, before wrapping her whip around Storm and pulling her towards the ground. Storm pulsed lightning through the whip, electrocuting Wonder Woman, but her powers were nowhere near as destructive as Thor's had been. Ignoring the electricity conducting through her, Wonder Woman flung Storm straight into the hull of the helicarrier, causing an explosion on impact.
Wonder Woman then flew away, reaching a safe distance from the helicarrier, where she reunited with her friends, who had escaped while she had fought Storm.
Superman floated up before the rest of the group. "We need to find out what is going on here. It seems they wanted that Kryptonite because they planned to attack me with it. The problem is, if we don't have it, and they don't have it, who does?"
The Justice League turned to see that the helicarrier was buzzing with movement, and that several Avengers were ready to fight them.
Superman looked up as Green Lantern appeared next to the group, Flash beside him.
"We're all here, and they're all here, too. We'll never be able to find who's really responsible for all this with these guys breathing down our necks. We have to beat them. Right here, right now."
