Arabella looked around the empty apartment room. She decided to move to America to travel the world and encounter magical creatures. She had a deep love for any creature, after all, she was a Scamander, which creatures were attracted to her as well. She placed down her box and she pulled out her wand as objects begin to float and move by themselves. She changed her last name to Parker, as only a handful of people know of her true identity since many corrupted wizards wanted her gifts for their own benefits.

Teddy's head was poking out of her bag, as he grumbled about how hot the weather is and how it's gonna ruin his silky fur. Arabella rolled her eyes at the diva ferret-like creature as she continued to use her wand to unpack the boxes and transform her room to her liking.

" Why do we have to move to a place where it's boring and hot" the javey creature complained as he used his paws in an attempt to cool himself.

"Hey, didn't we agree that we wanted to go somewhere that wasn't Britain and besides I think a change of scenery might be good for us" she said as the ferret creature grumbled more as he pouted. " Okay grumpy pants, how about we get some fresh air " she asked Teddy which he agreed, still pouting.

She grabbed her bag and put her wand back to her wand holder belt around her waist, she had made sure that her shrunk suitcase keyring was attached to her bag. Arabella wanted to make her magical suitcase into a keyring so she could easily bring it everywhere and she could use an engorgement charm to return her suitcase back to its original size.

She left her apartment as she started to explore the town, Arabella had soft brown, honey eyes that glowed from the afternoon sun which complimented her brown hazel hair that reached below her shoulders. Her outfit consisted of a white t-shirt with a cream-colored corduroy coat, along with a pair of black jeans and laced-up, combat boots.

She found herself underneath the road bridge where she heard a voice nearby, she suddenly felt something hitting her foot. It was a mini yellow car which she picked it up and looked around to find the owner. Arabella found a young boy with spiky brown hair, with glasses holding a remote control.

Raf looked up at the 17-year-old girl holding his toy car. " I believe this is yours" she said, she gently gave it back to the boy who smiled and thanked her.

" Are you British by the way? I never met someone with a British accent before" the brown-haired boy shyly said, Arabella gently smiled at his childlike curiosity as she sat down next to him. " Yes, I am British. I'm Arabella Parker, nice to meet you " She took out her hand which he shook as well. " My name is Rafael Esquivel but people call me Raf" he said.

In a short time together, they became instantly became good friends as he was explaining how he was interested in science and technology. Arabella was amazed and found out that her new school was the one that Raf goes to as well.

Raf was surprised at how friendly the brown hair girl was but instantly liked her warm personality and that she listened wholeheartedly when he explained his interest. He never had friends in school or in town before but Arabella actually wanted to be his friend which made him happy. She didn't tease him about how he was a nerd or made fun of him for being in a high schooler class at a young age, she only complimented and told him amazed at how smart he was which made him smile at her encouragement.

Now Raf was playing with his remote car while Arabella was reading her book on ' Fantastic beasts and where to find them' which caught Raf's interest by the colorful illustration of magical beasts on the cover. Arabella was comfortably reading as her jarvey companion was sleeping in the front pocket of her canvas crossbody flap bag.

Both of them flinched when they heard a vehicle sound along with someone screaming, Arabella put her book in her bag as she was about to take out her wand. A motorcycle jumped off the highway onto the road in front of them. The bike skidded to a stop and the both of them, jaws dropped.

" Whoa/Bloody Hell!" Raf and Arabella said at the same time, amazed by the stunt. The boy with jet black-haired looked terrified, " You have no idea" he said as he slowly hopped off the bike but the sound of cars screeching caught their attention.

" Well that doesn't look too good" Arabella commented seeing the two purple cars racing down the hill. What they did not expect was for the two cars to transform midair into giant robots. Arabella had seen Trolls, Hippogriffs, all sorts of magical creatures but this shocked her the most.

Arabella and the other boys backed away but freeze to mechanical noises behind them, the motorcycle was transforming too. It was blue, pink, and grey with a feminine body shape, her eyes glowed in an electric blue with accents of pink.

" This ends here cons" the femme robot said as the black hair boy grabbed Arabella and Raf's arms and ran away from the fight.

Arabella kept a hold on her hidden wand in her right hand as the boys watched the fight. " W-what are they?" Raf stuttered.

" Talking cars that turn into robots" the black hair answered. " Or the other way around " Arabella said as her body readies for action to protect those two. The female robot continues to throw punches and kicks at the purple robots. " This is for Cliff! " as she throws her hardest punch but the purple robot retaliates back as it shoots at her.

She manages to dodge them but the last shot hits her chest as she roughly falls down to the ground. Arabella saw another car jump off the bridge as it transform in mid-air, landing on top of the purple robot and punches the other one.

The yellow and black robot steps back only to step on Raf's toy car, Arabella winced at the smashed car which it turns to them, a series of chirps and beeps which somehow Arabella could understand, same with Raf.

" No problem. Really" Raf assured the yellow and black robot. A sudden attack made the blue-eyed robot go flying in the air before harshly landing on the ground. The two bots force him down as they point the guns at his head.

" Leave him alone!" Raf yelled, drawing the robot's attention, Arabella had her wand out. " Please?" he asked quietly but one of them walked towards them. " Bad call " the teen boy said as Arabella was ready to protect her friend, sending a Petrificus Totalus spell to the robot, as a white beam from her wand shoots at the robot, its body becomes stiff as it falls to the ground.

" The spell doesn't last long" she yelled "RUN!" she grabbed the two gobsmacked boys and ran away while the other robot was gaining on them, they hopped into a sewage pipe. Arabella turned around and constantly used the Stupefy spell to stun him but the robot gets dragged away and after hearing metal clashing, the yellow robot head appears. He asked if we were okay and a sigh of relief escaped her. " We're fine. Thanks for saving us" she said, Raf nodded at the robot. " Thank you" he thanked.

" Don't look back" the black hair teen ordered as we ran further down but Arabella waved at the yellow robot which he waved back with a happy chirp.

" What did we just see?" Raf asked as they continued to run down the drain. " No idea and I'm not sure I want to find out" he said but looked at the brown-haired girl, still holding her wand. " You need to explain what the heck you just did there!" he exclaimed, while Arabella could only nod to his question, she didn't want to obviate them so she hoped that they could keep it a secret, she trusted Raf but the other dude not so much but realized that the yellow and black bot saw as well.

Arcee and Bumblebee were at the base, explaining their situation. "And the Cons would have been scrap metal if I hadn't been distracted by the human" she finished off.

" Humans?" Optimus asked which Bumblebee explained that there were two boys and a girl though he had his thoughts on the human girl's strange ability.

" I guess both of them caught us in action, I don't know. I was a little busy at the time" she said, crossing her arms. " If the Decepticons are targeting us Anyone perceived as our ally. Will be at grave risk." Optimus explained which Bumblebee chirped in. ": Something strange happened while I was fighting the cons:" he explained which caught the attention of Optimus and Arcee. ": The girl did something to temporarily stun one of the con, long enough for them to escape:".

Optimus hummed at his explanation, thinking how the girl could possess the abilities to defend against the Decepticons.

Arabella and the other boys exited the sewage pipe. " What's your name?" the teen asked. " I'm Raf and this is Arabella. What's yours?" he introduced, the black hair boy said that his name was Jack.

Jack stood in front of Arabella. " Okay what did you do back there?" he asked which Raf wanted to know as well.

Arabella sighed exhaustedly, from the action today. " I'll just put it simply, I'm a witch from England" she said.

Both boys were silent, after seeing giant robots fight, well let's just say that they were willing to believe in everything. She explained the wizarding world to them and told them to keep it a secret or if someone else knew, they would have their memories wiped out from any memories related to magic so both boys wholeheartedly promised to keep it a secret but something told her deep down that this was just only the beginning.
