There are many who ask who "Demolition Angel Vividosk" is beneath the bright yellow mask and hazard-striped flak dress. There are any range of guesses, from the average construction worker seeking to make her world safer than it was for her growing up, to a higher-class lady looking to get her hands dirty and prove herself. But what they all have in common is that they assume that there was a childhood stage.
Her origins were far more simple, but no less challenging. Starting as a typical social robotics AI board, she was installed into an advertising droid in a factory mix-up, and by that point her AI was deemed irremovable due to the potential harm it would cause, instead ruling that her status as an advertising droid was to be treated as an internship. She tried to live that life as best she could, choosing the name "Oskie" for herself, but after finding a friend in another social robot, a boy named Relik, she realized just how much more she could've been doing if she had only been born with the frame that was intended for her. If she didn't fade into the background like all the others built using the one she has now
However, her path was set on a new course after she realized just who that boy was; The mysterious hero known to most purely as "Titan II". And she had found out after seeing him on the receiving end of a losing battle with a strange alien warrior that had him dead to rights.
She didn't have much at that time. Just a monitor to display images, a motor that let her travel at most 15 miles per hour with the potential of burning out, and a dense but fragile frame. But a bit of plywood leaning against some concrete, some quick math, and the pull of gravity turned her into a cannonball headed right for the warrior's face. The impact totaled her chassis, but it bought Relik precious moments to finish the battle quickly and escape with her in tow, remains wrapped in an oil-stained hazard vest, as he sought to have his creator fix her.
When her AI board was brought back online, she had realized something in that moment. There were many things going on in the world. People that were in danger, and even a hero like Relik was getting overwhelmed. She couldn't just let it happen like this anymore, and so she turned down simply having her helpless little frame rebuilt, even if the process of moving her into something more drastic could damage her. With both the talent of Relik's creator, and the input from a strange machine that claimed to be from beyond the stars, they built her a new body. One that would allow her to protect the world, and experience its wonders in the way she had been meant to.
She could do so much more now, outside of having a more typical humanoid body. She could create concussive bombs as if by magic, forming in her hand with but a second of concentration. She could see a new range of things with infrared and heat sensors. She could speak aloud without being hooked up to a sound system for the first time in her life. And she was intent on using all of these to help her friend help the world, using that brightly colored jacket as the basis of her new outfit to symbolize a brighter tomorrow... and to catch the attention she's been looking for.
