"Well?" Robin asked Spoiler as she continued working on decrypting the cerebral interface for this alien prisoner.

"That should just about do it." Spoiler said as she finally finished the decryption and proceeded to unplug their new friend from the computer system.

"Damn, you did it." Lightning said as they watched the cords unhook themselves from this guy.

"Sorry it took so long, but it took awhile for this guy, whoever he is, to gain enough awareness to realize that I was trying to help him and then he stopped trying to resist my efforts. I think he initially saw my actions as more of Cadmus's attempts to mess with his systems, so I can understand why he'd try to repel them." Spoiler said as the alien finally regained consciousness and broke free from his remaining restraints.

"Welcome back." Robin said.

"Give me a moment, I need to get my bearings, since this is the first time I've been in one piece mentally in years." the alien said as he waved his hand and the door to his cell opened.

"Gotcha. I see you're healing nicely." Robin said as the guy looked like he was already returning to pique condition.

"My system is self repairing, yes and now that I'm back to decent condition, I can take a moment to properly thank my liberators. Robin, Spoiler and Lightning." the alien said.

"Okay, you apparently know our names, but what's your's?" Lightning asked.

"My name is Querl Dox, but you can call me Brainiac 5 or just Brainy." Brainy said.

"Wait, green skin, those dots on your chest, the affinity for computers and your name is Brainiac 5. Do you have any connection to the Brainiac that's one of Superman's greatest enemies?" Robin asked.

"Unfortunately, but I'm not like him. I'm his great grandson." Brainy said.

"Wait, what? How?" Lightning asked.

"Wait a second, Querl Dox, that name's not just an alien name is it?" Robin asked, since he'd seen enough with Batman to be able to guess where this guy is from.

"No. I'm from the 31st century." Brainy said.

"You honestly expect us to believe that?" Lightning asked skeptically.

"I know how it sounds, but it's true." Brainy said.

"We can settle this later. Right now we're here on a mission." Robin said.

"What mission is that? Perhaps my 12th level intellect can help, especially since even though I'm no longer connected to Cadmus systems, I still have access to their database. Mainly because I was their database, meaning I have access to all their files and security protocols." Brainy said.

"Fair point. We're looking for a Project Kr. Codenamed Superboy. He's our objective, but a secondary goal is to release any other prisoners Cadmus is using as lab rats." Robin said.

"Then I believe I can help, especially since my ship, which was captured when I was, can serve as our escape vehicle." Brainy said.

"Great, but we have two other teammates who could also use a lift. Are you sure your ship will be big enough?" Spoiler asked.

"It will be more than sufficient. That is, assuming it can still fly considering the fact that Cadmus has most likely been cannibalizing it for years." Brainy said.

"Sounds like we might have to improvise our exit." Spoiler said.

"Which was pretty much the plan. But now Brainiac, lead us to Superboy." Robin said and Brainy nodded as they left the chamber.

"I guess after seeing Powergirl, I was expecting the rest of Cadmus's creations to look more human too. But not like this." Lightning said as they approached the Project Kr vault.

"Yeah, tell me about it." Spoiler agreed, since they'd passed several of Powergirl's 'siblings', but unlike her, none of these creatures, which Brainy had called genomorphs, looked remotely human.

"You should not judge them based on their appearance. Just because they are not human does not mean they aren't worth saving." Brainy reminded them.

"Not to mention Powergirl would kill us if we even considered leaving any of her family behind." Robin said as they reached the doors.

"I must warn you, while Superboy is in there, Project Kr also contains another prisoner. Another alien they captured aside from me and locked in here because she was too dangerous to keep with the others. This is the most highly secured vault in the building." Brainy said, right as Powergirl and Wonder Girl joined them.

"I see you found an extra." Powergirl said.

"He calls himself Brainiac 5 and he knows the layout of this facility." Robin said.

"Let me guess, you're a Coluan and Cadmus found a way to use you to power their servers." Powergirl said, since her big sister had insisted on making sure that she knew all the different aliens she might go up against.

"Correct. Your brother Superboy is in there and so is another prisoner. Another alien." Brainy said.

"What kind?" Powergirl asked.

"A martian. A white one, but not like the kind who hunted Martian Manhunter. She's different." Brainy said as Powergirl and Wonder Girl exchanged looks, since they both knew how J'onn felt about White Martians.

"We'll figure it out when we get in there. Can you open the doors or do I need to punch them open? I'm fine with either option." Powergirl said.

"Allow me." Brainy said as he waved his hand and the doors opened.

"That works." Powergirl said as she led the charge inside to find two different containment pods that reminded her of her own imprisonment. The first one contained what had to be the reason they came here for. Superboy looked like he was in some kind of induced sleep and was wearing a pure white outfit with a red house of El crest on his chest. He looked like a younger version of Superman, though not quite as identical as she looked to Supergirl. Most likely because only half his DNA was Superman's, while the other half was Lex Luthor, while she was a pure genetic duplicate of Supergirl.

In the other pod appeared to be a the white martian, though it appeared that she'd taken on a more humanoid form than what Powergirl had thought white martians looked like and she appeared to be a fan of Martian Manhunter, since her outfit resembled his own suit.

On her head, over her eyes and her bright red hair, was some kind of device that Powergirl assumed was some kind of psychic dampener to keep the Martian from using her powers.

"Can you disable that psychic damper without releasing her from her pod? I want to make sure of her intentions before we let a potentially dangerous alien out of her pod." Powergirl asked, since while she felt sympathy for this martian, she couldn't just release her without knowing her intentions.

"Yes, of course." Brainy said as he disabled the psychic dampener, which immediately flew off the martian's head and her eyes opened and she saw them.

"Thank you for removing that device, but you won't release me yet, will you?" they heard a female voice say in their minds.

"Not yet. We need to be sure that you're safe before we release you." Powergirl said apologetically.

"I understand. But I mean you no harm. My name is M'gann M'orzz and please, allow me to link your minds to mine so you can see my story and believe my intentions." M'gann said telepathically.

"Do it." Powergirl said as M'gann's eyes glowed and they all found themselves suddenly watching M'gann's life story.

Particularly how she was half white martian and half green martian. How she'd refused to participate in the extermination of the green martians and how that had led to her being marked for death, despite the fact that she was only a child in martian terms.

They watched as she and another white martian, an adult one, fled their homeworld to Earth, hoping to find the Martian Manhunter and help him, but they'd been separated shortly after arriving on Earth and how M'gann had been captured by Cadmus.

But there was one detail that Powergirl noticed in particular.

"Your mother was J'ann J'onzz. J'onn J'onzz's sister. Which makes the martian manhunter your uncle." Powergirl said.

"That is, if he believes it, since he never met me." M'gann said sadly.

"We'll make him believe you. But now, let's both you and Superboy out of there. Release them both and then call the League." Powergirl said and Brainy nodded as he opened both pods and while M'gann walked out herself, Powergirl and Wonder Girl both rushed forward to help Superboy until he woke up.

"Okay, let's get out of here." Powergirl said, since they'd accomplished their primary mission.

Superboy is portrayed by Tom Holland and M'gann M'orzz is portrayed by Zendaya.
