In one of the many trains that zipped through the air in Iacon City stood a small, predominately purple transforming bot. She wore a small, tense smile as she rocked back and forth.

The few bots left on the train repeatedly turned their eyes to her. She figured it was likely because of her clear enthusiasm, but she really hoped it was because they recognized her from the ten seconds her image appeared on the news. With less bots on the train, more attention would of course be on her. Two of the bots were mining bots, born without transformation cogs, and she imagined they would look up to her even more.

"You're kinda freaking me out, lady," one of the miners remarked with a step back.

Ouch.

She hoped nobody could sense her disappointment. For a moment, she fantasized about what she would have said if she was one of those jerks who always belittled the miners.

As a golden tower came closer into view, a transformer snapped his head back and forth between the purple bot and the tower. "Hey! Aren't you the new—"

"—Yes!" The bot exclaimed as she threw her fists up.

The train stopped at the gleaming tower. She squealed and leapt to the train's opening door. She made a quick turn and grinned with a click of her tongue. "Call me Charoite! Well, it's been real, but this hero's gotta shape and mold the future!"

She exited the train and stepped up to the tower's closed doors. As the train immediately sped away, Charoite felt a surge of anxiety. She however could just fly to another set of doors should this high-set pair not open. She took a deep breath and knocked.

"Who is it?" A femme's forbidding voice asked through an intercom.

"Charoite?" She hated how scared she sounded—and felt. She calmed herself as much as she could and steadied her voice. "Charoite. I'm here for my first day. You may recognize me from the ten beautiful seconds I was on the news. Yes, I counted! Then again, you work and live here, so you may have seen me more than—"

The doors slid open in a stunning second. Airachnid, a dark bot with way more than the usual two legs loomed over Charoite. Her two main purple eyes stared her down, then she turned her head in both directions, staring at her with the rows of smaller eyes on the sides of her head.

Airachnid resumed her straightened posture. "He should be in shortly."

Charoite watched in relief as Airachnid sauntered away. She wasn't exactly known as an approachable bot, but she apparently could be downright terrifying in person.

Charoite took a seat on one of the two blue couches. They seemed to be made of some sort of stone. They were blue but had golden lines in no pattern spread throughout. She traced a finger on one of the golden lines and noticed it was raised. "Huh, must be painted on."

"Ah! Charoite! Welcome to my humble abode!"

Charoite turned around and saw a blue bot with golden, angel-like wings. He made his way in front of her.

"Sentinel Prime!" Charoite shot up from her seat. "I'm Charoite!"

"Ah…we're gonna be seeing a lot of each other. Call me, 'Sentinel.'" Sentinel extended his hand.

"Oh, okay, wow!" Charoite vigorously shook his hand. THE Sentinel Prime! He wants me to call him "Sentinel!"

He sat down on the couch across from her and gestured for her to sit back down.

A/N: After a long and eventually annoying time trying to come up with a name for the OC, I realized Charoite was the right call. Since she's purple, I looked up purple gems, and I found one called, "charoite." I then found out that there's a religion that associates it with change, discernment, and, well..transforming, surprisingly! Change and discernment are key factors in this story, which made the name an even better fit than I thought it would be. Anyhow, hope you all enjoy!
