Saiyan Inventor, but an S-Class Threat to S. H. I. E. L. D.

When the fighting talent of a Saiyan merges with the brain of a genius inventor, her life trajectory is destined to no longer be "normal". During the day, she is a super freshman at MIT, a special consultant at Star Laboratory, and a scientific research genius known as the "Tony Stark" of the new era. At night, she put on another face—— International monster thieves on the global wanted list, shadow ghosts on the Internet, ever-changing treasure hunters, alien travelers who saved Krypton from the crisis, urban legends in the night... She has saved the world and stolen treasures; she hides her power and carries secrets. Until one day, she "stole" a fire helicopter—— Then, the whole world exploded. SHIELD held an emergency meeting overnight: "Classify it as an S-class threat." Batman frowned: "This character's purpose is unknown and extremely dangerous." Superman looked up at the sky: "Maybe, this... Is just a lonely child?" While everyone was on guard, this "world-class threat" was chewing on energy bars and sighing at the experimental data: ——"QAQ, I just want to build a space-time machine and go home, so why have I become a key surveillance target around the world?!" —————————————————————— Ps: The heroine has scientist and Saiyan ancestry, high IQ + explosive strength. The world of this article is a fusion setting, mainly DC+Marvel, sci-fi+fantasy crossover, and a combination of wits and force.
