Multiverse of Marvel Novel

In "Multiverse of Marvel" by thelightedghost, a profound event has occurred, resulting in the death of an ancient being. This incident is classified as a Nexus Event, beyond the control of the TVA, and cannot be undone, drawing a parallel to the death of Christine in "What If?". John finds himself in a precarious situation, accused of a crime that warrants immediate pruning by the TVA. However, he protests his innocence, pointing to another party responsible for the situation. The story follows a cinephile and an otaku who are transported across dimensions, acquiring an incredibly powerful yet restricted system. Initially thrilled, they soon realize the perilous nature of their new world. The narrative promises not to alter established canon until the conclusion of the New York War. The author notes the MC will grow into a powerful character, acknowledging potential language and grammatical limitations due to being a new writer with a second language and no editor, but is working to improve. The work is a Marvel fanfiction with elements of world-hopping, systems, game mechanics, and a weak-to-strong protagonist. Romance is present but not a central focus.
