What you recognize I don't own. As always foreign, alien and sign language is in asterisks while thoughts are in italics. The Justice League is aware of the Transformers and occasionally teams up with them during international crises but doesn't know about their adoptive human child through the will of the child's parents and the Transformers also known as the Cybertronians trusts the Justice League as far as international crises go but that's it. I am going to do my best to keep primarily to the cartoon of the Justice League but I have also read the death of Superman arc and am going to incorporate it into the story as well
Katherine was packing bags in a room that was too big for her but that was because it needed to be big to fit her family
"Are you absolutely certain about this trip Katherine?"
"You guys already signed the paperwork Optimus, besides this is an official school trip"
Her family was the Cybertronians who had raised her since she was a baby
"Yes but that was before the trouble in Metropolis recently"
"You guys trust the League to protect everyone if it's needed or Superman only if it's his enemies"
"Yes but..."
"There's also me, I can protect everyone if need be and you know it and like I said it's an official school trip that you already agreed I could go on"
"Yes but if there's trouble you use your internal shielding which doesn't weaken you"
"Actually if I use it constantly it does, at least I won't get nothing more serious then bruises inside and cuts on the outside"
"Actually you would get very minor internal bleeding and broken bones with your internal shielding, and we didn't know using your shields constantly still weakened you"
"Neither do I necessarily but it does, and I guess I forgot that my shielding only protects my organs due to the fact that I don't use just internal shielding too often"
"Good point we'll leave you to finish packing then, you have to be at the airport by six"
Katherine finishes packing and ultimately arrives at the airport fifteen minutes before everyone else who starts staggering in five minutes before six, but everyone was there on time
"Okay everyone we have a lot to do to check in thus why we're so early"
Katherine then speaks up
"I might have something to make things go a bit faster"
"Oh?"
"Yes, I already printed all of our tickets and I also printed these tags"
Katherine reveals tags that she had made up with all of their names and also the school they attended and the school's address for all of their bags
"This ways if something happens to our luggage at least the bags will get back to school eventually"
"Good thinking Kerenai, everyone tag up"
Everyone puts on the tags and ultimately while it doesn't make things go a whole lot quicker it does go about five minutes faster with Kerenai's ideas and they take off on time at ten in the evening and arrive safely at three in the morning local time. No one had noticed that Katherine had slept lightly on the flight due to just how awake she acted once they were off the plane
"Okay everyone we'll check into the hotel that we've arranged for and then everyone gets a day to recover before we have school activities"
Katherine was the most recovered by noon on Sunday
"How can you be so chipper after that long a flight?"
"Training, lots and lots of training flying all over the world"
"Why would you go around the world?"
"Because she's an EDC kid Julie, they get weird training and she probably slept lightly on the plane too now that I think about it"
"You're right Sarah I did sleep lightly, after all I was next to the emergency exit door if something should have gone wrong I would have had to open the door and made sure everyone got off the slide safely"
"Go figure"
Ultimately everyone recovered by Monday and for three days things remained pretty calm, only two emergencies that required Superman happened and that was more because of size than anything, one emergency was an apartment fire while the other was a combination of a gas leak and a plane that had an in flight emergency that the pilot couldn't take care of in the air due to being unable to do a go around because of low fuel levels, and then on Wendseday everything went wrong, but while most people went into hiding Katherine joined the fight and was doing okay despite fighting against the problems Weather Wizard was giving with crazy winds and also snow, plus she was also dealing with Toyman when suddenly she got overwhelmed by a couple of small time crooks but she was working her way free when suddenly she was stopped with one single phrase
"Hold it right there or this man dies!"
Kerenai, who had been struggling against the ones holding her stopped cold when she saw no less then three people holding Superman hostage with Kryptonite and she was certain that the guns also had Kryptonite in them as well in the form of bullets and thus she immediately stopped her struggle right then and there just sagging into the arms in obvious defeat. She was confusing the Justice League with her actions not knowing her training or who had raised her (though they were well aware of the Cybertronians and their history with each other before the factions were no more except in certain functions where they needed to be classed as Autobot or Decepticon) Superman though spoke up for the league's benefit for the most part though he didn't know that his words also affected Kerenai
"Don't worry about what happens to me, just stop them"
Kerenai, though still acting defeated secretly prepares herself to move at a moments notice, not even giving hints that she was preparing for action by tensing muscles but as soon as her captors loosened their grips in preparation of fighting the Justice League one handed (the League hadn't moved in case of risking her either even though she had actually been holding her own against Toyman's tricky weapons) she went into a blur of action taking down her two captors and then rushing towards those that had Superman in the Kryptonite trap, she even during the fight actually succeeded in punching out Poison Ivy though she did get hit by Metallo which temporarily took her out of the fight but she succeeded in dealing with the henchmen afterwords. After the fight Superman needed to be taken to their headquarters for treatment for Kryptonite exposure but otherwise he would be fine, the League also insisted on checking Kerenai out and discovered that she had bruised ribs from the punch from Metallo but otherwise she was alright as well
"You got lucky, you should have broken ribs from a hit like that not bruised, the rest are all minor scraps and scratches, including the one I had to stitch up simply due to the length of the cut not the deepness"
"I'll explain things once Superman is awake, but only to the known founding members, they can decide what to do after that but for now only the founding members can know what's up, and I need to make a phone call in private now that I've been medically cleared"
"Of course, I'll take you to a private room that you can either call a regular phone or do a teleconference with"
"Thanks"
Kerenai decides to go for the teleconference option knowing that if the battle had been reported on TV then her family knew what had happened and would want to actually see her and she was right, both Primes, Galvatron, Ratchet, Hook and Starscream were there along with Soundwave as the communications officer
"Hey guys, I'm actually pretty fine, according to the League medic I have bruised ribs and the rest are scraps and scratches, oh and I have stitching on my leg, but that's more due to the length of the cut then the deepness apparently"
"How long was the cut?"
"From the knee to the ankle Ratchet, oh and I decided the founding members would know the story behind me and they could make the decision on letting the other league members know the story"
"No only the founding members for now K, we have our reasons behind that"
"Very well I'll let them know your rules, I'm sure that they'll abide by them"
Ultimately Katherine stayed with the League until the next Wednesday but finally Superman was recovered enough to hear the story and while they weren't happy about only the founding members knowing the truth they knew that they had to abide by them
"Well at least now we know about you and won't worry as much but don't think we won't still protect you at need"
"I know"
Suddenly alarms went off and there were several League enemies and then Katherine speaks up
"I'm coming with you"
"Oh no you're not your safety..."
"Sorry you got no choice, I see Quintessons, Sharkticons and...yep there's Cordinleys as well"
The League looks at the screen and sigh in unison knowing that Katherine was correct in that she was now going to be getting involved because they too recognized EDC enemies and the fight was intense. Katherine would have continued fighting without using her powers due to constantly able to change out her bullets from her gun because of other police officers but then she noticed that the Cordinleys seemed to be immune to the weapons and as such knew what she had to do
"All League members who don't have any armor or are invulnerable need to get the police, civilians, and themselves out of my way and stay that ways, everyone else need to be careful"
"What for?"
"For this J'onn, fortunately while you still need to be careful with your ability to go intangable and able to read my mind for when I am ready to do what I'm about to do you should be relatively safe"
Katherine then puts her hands together where the ends of her palms touch together and then calls something out
"Arranyan power blast!"
J'onn sees a burst of light and also feels what seems like a blast of heat coming from the attack. When she was done they could both tell that the enemy had been seriously hurt but it was still able to fight
"Go figure, Arranyan sword"
Suddenly Katherine is holding a sword and joining the fray physically, but everyone could tell that she was weakening, fortunately by that time the Cybertronians had joined in the fight and one was with her
"Katherine get on Ravage and get yourself out of here"
"You dock with Blaster and then I'll get on Ravage Rewind you're injured and need treatment but you won't be able to last unless you dock with Blaster immediately"
"But..."
Fortunately Blaster had gotten there by then and as soon as Rewind docked with Blaster Katherine got onto Ravage's back
"Okay Ravage get me out of here"
Katherine gives Ravage directions to the League base where she knew there were League members still there on standby, as soon as she got off of Ravage she passed out and was taken to their medical facility while Ravage stood outside ready for trouble. Fortunately the battle ended about ten minutes later and then everyone was back at the League base where there were explanations given
"She's currently in our medical care facility being watched over in case something's wrong due to the way she just passed out"
"Unfortunately that's pretty common for very complicated reasons and when she uses two specific attacks that we'll tell you she needs specific EDC energy drips to recover, drips to replace sugar in diabetics or calorie drips will also work but only under specific circumstances, have you started her on any drips?"
"No we have someone monitoring her without a heart monitor in case something goes wrong but no drips"
"Good that would have done more harm then good for reasons that we can't explain because we don't really know why it happens"
All of a sudden Supergirl comes rushing in but stops suddenly at seeing the Cybertronians due to not hearing any of the explanations yet as Katherine's medical monitor
"Supergirl what is it? Oh and it's okay to speak in front of these guys"
"It's Katherine, it's...not something I can explain actually"
"Ratchet..."
"On it Prowl"
Ratchet goes into their medical facility, or at least to the door and does a scan of Katherine and then curses in Cybertronian and then gives orders in English because the scans revealed the reason why it was like she was seizing and yet wasn't at the same time thus the reason she wasn't being hooked up to medical equipment yet, there was also the fact that she was still unconscious despite having been there for several minutes already and when one person touched her it was like she was cold to the touch despite not being hypothermic or near anything cold
