I don't Own My Hero Academia. alternate time line
Small square metallic object with three color changing lights calls for help in a teen female voice. A teacher who is male age 27 finds it. the device contains this world's Uraochako's mind and soul. In this time line she was a genius in programming and robotics. however she wanted to be a hero and went to UA.
her mother was also a genius but due to jealous rich college classmate was forced out of the scientific community. She fell in love with a construction worker and helped him make his own company before marrying.
at some point Uraochako's left leg was injured to the point amputation was necessary. because of this she had the a robotic replacement and schematic memorized. this was why she learned robotics. before it was developed she was transferred to a support hero course. Her mother helped some in the creation process but it was mostly Uraochako's work.
she was targeted by a villain corporation while at a scientific convention. this corporation was run by her mother's jealous classmate. a fake accident was arranged. Uraochako's mind and soul were trapped they were intentional trying to make her seem like an AI and make her be used to make inventions for them to profit from.
they didn't know her level of programming expertise so she was able to build a backdoor to retain and maintain her memory before being trapped. she figured out how to make hard light projections and gave up a inefficient version with back doors that she would use to control them. she used them to destroy much of the corruption corporation and escape but much of the memories made after she was transferred to this form were damaged.
