Marvel: The Silver-Haired Hacker and Her Mecha Fleet

When Mira Vale transmigrates into the dangerous world of the Marvel Cinematic Universe in 2008, her only goal is to survive the upcoming apocalyptic events. However, she didn't come empty-handed. Bound to the terrifying "Antikythera System," Mira possesses the absolute authority and world-ending technology of the Siren Experimental Agency. With a cybernetic mind capable of crushing supercomputers and the ability to summon massive, reality-warping mecha riggings, staying under the radar quickly becomes impossible. From anonymously hacking Stark Industries to prevent the birth of the Iron Monger, to utilizing epigenetic inhibitors to stop Dr. Connors from becoming the Lizard, Mira uses her advanced silicon-based intelligence to systematically dismantle the timeline's greatest tragedies. But her actions haven't gone unnoticed. Nick Fury is paranoid, S.H.I.E.L.D. is hunting the mysterious "Mecha Girl," and to make matters worse, the Siren System has just deployed a terrifyingly powerful, expressionless civil engineering loli to live in Mira’s tiny Queens apartment. Surviving Marvel was supposed to be a stealth mission, but Mira is about to build an empire. — Description from novelcodex.org
