Sophie followed after Superman, her brain analysing how he was flying and copying it onto herself. She found out she was conserving more energy while moving faster than before. Sharp turns would be taken faster and accurately while stopping would be instantaneous with no cause of environmental damage.
'I'm learning so much,' she thought to herself.
"We're landing," Superman informed her as he started to descend. Slowly, dust he landed onto a car junkyard where Superman walked to a phone booth.
"You making a call?" Sophie asked him. Superman just gave her a smug look before opening the booth.
"Computer, identifying myself, Superman 01, override allow transport to Sentry, female, B05," Superman said before a camera suddenly appeared from the roof and proceeded to scan him.
"Confirmed, Superman 01," the computer said before the camera turned to Sophie and scanned her. "Saved file. Welcome, Sentry, B05." The wall of the booth suddenly opened up showing some kind of crazy technology.
"I'm going in first, follow after," Superman told her before he was bathed in light and disappeared. Sophie looked at the booth with comprehension before shaking her head.
"Nope," she said before taking off to the sky. The booth closed its door seeing her go away.
'Why would I follow him like an idiot. This is DC, for all I know if I go there then I might find that Superman is fighting someone like Doomsday or even Darkseid and I have to help. With my noobness, I might as well label myself as 'punching bag' compared to their experience. Unless I know and can see where I am going, I won't follow any of the heroes till I know I can handle myself well enough,' she thought to herself as she increased her speed.
At The Watchtower
"Superman, you said you were bringing in a powered individual for evaluation. I have not seen her," Wonderwoman said to Superman who was standing awkwardly staring at the Zeta Tube.
"I think she just bailed," Superman said as he embarrassedly scratched his neck.
"What exactly did she do?" she asked curiously. Most if not all of the metahumans or aliens Superman has fought or encountered have tried to kill, control or seal him in another dimension in order to rule over Earth. Wonderwoman was sure if she fought with the villains Superman fought on a daily basis then she might actually die which makes her have great respect to this warrior yet nonwarrior of a man in front of her.
"When I found her she had collapsed a dormant volcanic mountain causing it to erupt. She was also wearing a Kryptonian suit with the House of El coat of arms and thus I think she is Kryptonian, no matter how hard she rejects it. She calls herself Sentry," Superman explained.
"Hmm, collapsing a mountain is quite the feat of strength. If you think she is a Kryptonian then you were right in trying to bring her here. Most of the Kryptonians we have met are ready to destroy Earth and make it a new Krypton, she could be the same," Wonderwoman said, making Superman nod in agreement.
....
Sophie had gotten her backpack back and was now heading back home. The transformation had taken over the better part of the day and with the eruption, she was sure the schools were closed. She had to reach home or everyone would be worried. When she got to her house, she saw the family van packed to the brim while parked on the driveway. When she got in, Abby appeared out of nowhere, giving her a motherly hug of love and relief.
"We were so worried. You weren't picking up your phone, saying it is disconnected, and with the eruption happening, the earthquakes, we were told to evacuate immediately," she said while still trying to crushing the living breath out of her lungs.
"I wanted to leave you but Fred was such an annoying crybaby we just had to stay," Dennis said, trying to be macho if his eyes weren't red and puffy. Sophie just gave him a small smile, not calling out his bluff. Stacy had taken out her phone and was scrolling on it again.
"Someone stole my phone and when I tried to get back here with all the earthquakes, I just thought it was reasonable to just bunker down somewhere till everything calmed down for a moment before going on," Sophie assured them.
"Smart, you might have hit your head on something and ended up crashed under rubble," Bobby said to her. Abby let her out of her hug then went to the kitchen.
"You need something to eat? I made some sandwiches we could have eaten on the road, don't want them to become soggy," Abby said as she practically pulled out a tray filled with cut out sandwiches with no crusts on.
"It's fine, I don't think I'll have an appetite for sometime," Sophie rejected. 'Or ever, I am a self sustaining.'
"I'll go to my room and brood or something," Sophie informed them and walked to her room, locked it before taking out her chemistry book.
Going through the periodic table, she memorized the atomic values of each element before she put down the book and decided to have her practice. Molecular Manipulation is an overpowered power that no villain had any right to have. The ability to control, shape, absorb or create matter is right at the edge of belonging to reality warping. Using this power, Molecule Man had created a whole universe, fitting it inside a box just to flex his power. What's overpowered? That is! Creating an entire universe is just way harder than controlling it according to her.
So, her first element to create was gold. Why? Gold was just too tempting to create. It was the next hard currency if one would destroy the American currency and it's just too shiny. However, she was off by a margin and ended creating something else entirely that just crumbled to nothingness.
Not discouraged, she continued practicing and on the third try, she had created a four kilograms nugget of gold. She shaped it into a bar, smooth and even like it just got out of been processed. If she were to sell it then she would make quite a haul. But, for the moment, she would stick to practicing.
So, for the entire night, she continued to practice the Molecular Manipulation power, using her speed so that the night would pass a lot more slower than it should have. Doing this had made her master her bioelectric forcefield to a point where she could move in light speed and not even cause the tiniest gust of speed to happen. (A/N: Don't Tell me it's impossible, if an object with mass can move FTL, then this is possible.)
Due to the scare of the previous day, school was still out and understandably so. Knowing you were facing an extinction threat and surviving it would make anyone feel unmotivated the following day. So, Sophie decided to take this day as her debut as Sentry.
"I'm going out," she announced to everyone.
"Hey, have some breakfast first!" Abby called out to her.
"I don't think I can, I raided the fridge last night, I'm still trying to digest something," Sophie declined as she shot out of the house. Before going into speed of light, appearing above Metropolis with her hero costume on.
"Let's make this a productive day," she said to herself as she looked down towards the streets.
A few minutes of watching and listening made her zeroing to a speeding minivan. Looking inside, she saw a woman in labor seated on the backseat chiding her sweating husband to go faster. The man, under heavy stress and quite scared of his punchy hormonal wife, was hitting 80mph nearing a junction. She just knew he would ignore the stop sign caus fuck it, right? This was an accident waiting to happen especially when a pick up truck with manure would use its right of way excuse to plough through the offending minivan, killing the man and woman.
"Haa," she sighed softly as she floated right in front of the pick up causing the driver to stop in panic and fear. The residents of Metropolis don't have good memories with flying non-Superman objects.
"W...Who are you?" he asked, rising his window like it would protect him at all. She did not answer, only wait d for the minivan to sped past the junction and flew after it. She heard something flying after her and looking at the direction it came from, saw it was Superman, quite a distance away but she knew he could see her just fine considering he was smiling at her.
'Whay does he want?' she asked herself as she went back to concentrating on the task ahead.
She had to stop a few more cars before the minivan arrived in the hospital making her land beside it as the nurses were taking out the moaning soon to be mother.
"Don't mind me, I have a bone to chew with him," she said before pinching the soon to be father's arm, as gentle as she could, but it might as well be a vice grip to the man.
"Do you know just how many traffic laws you broke with that stunt of yours, huh? How many times I had to save you, dumbass? You could have died six times and be flagged down eight times due to your stupidity! Next time, do better!" She released the crying man and flew back to the sky, meeting up with Superman.
"You ditched me," the man said, slightly hurt.
"Yeah, well, I don't trust any man leading me to a suspicious portal," she answered, not missing a beat. Superman was shocked by the answer, probably not used to anyone distrusting him. Even his villains knew he was such a trustworthy person it bordered naiveness, they often take advantage of that.
"You did a good job back there, color me impressed," Superman continued.
"Thanks, I just had to step up when I saw where he was heading," she told him. Superman nodded.
"Look, if you are still having trouble with trouble with your powers then you can count on me to help you,"
"Why?" she asked but she knew it was because Superman was just like that, a nice guy.
"You need my help and I want to help. Besides, I would have wanted someone to help me control my Kryptonian powers. Also, it will help me keep an eye on you while you do this hero gig,"
"Basically you want me to be your sidekick?"
"Mentor, I will be your mentor," Superman corrected her.
"That still means I will be your sidekick," Sophie said with a deadpan.
