Can you recommend some novels where the protagonist is invincible?

Keeley, a simple plain Jane, hits the jackpot. [No, she did not win the lottery!] At least that's what she thinks when she marries the most eligible bachelor in New York City: Aaron, a wealthy cold-hearted heartthrob and Tycoon. She wants to show the world that she deserves her position and bends over backward to fit into his world. One beautiful day, Aaron hands her a document asking her to sign. A divorce paper... "She's pregnant, and I need to take responsibility." That is the last thing that keeps on playing in her mind before she takes her last breath. Keeley dies, a 'hit and run'. [End of story. Not!] For some unexplainable reason, she wakes up as her younger self. A young high school girl, around the time when she first meets her cheating husband. Remembering her life with Aaron before she died, she makes a promise to herself that she will do everything in her power to avoid him at all costs. Will she be able to keep her promise when Aaron has his own plans as well, specifically for her? Or will she repeat history and fall for him once more... Why not journey with me and find out the truth behind their story. *Cover art by polkadottedscrunchie*

A man that doesn't know his past, except for specific memories, was suddenly throwed on a weird but familiar world, in a dangerous situation. And now he has to survive in this world without any guidance but a system that came out of nowhere. Read the Tags. I placed a lot of Tags that has mature content as this novel will be full of spicy lemons. But, of course, it will have plot as writing too much lemons is mind tiring. Have a good time reading it. Also, if you see mistakes at the beginning, don't worry, it becomes better as you read. If you understand me.( ͡° ͜ʖ ͡°) All the rights of the works I may use as reference are from the respective Authors, with the exception of my OCs. Also English is my third language, so forgive me if you see many mistakes or chronological errors.

It sucks that of the two Invincible Self Insert fanfictions I have found, neither reliably updates. So here I am to fix that by bringing the world an Invincible Self Insert fanfiction by an author with a proven track record of reliable updates, finished stories, and the full capacity to play with the plot however I want without twisting the traits and tone of the characters. So strap in for a good time. Fair warning, the SCI-FI will be harder than what is seen in the comics and TV show and some of the plot conveniences that get thrown out as soon as they are introduced are gone. Props to LordValmar for the cover image Massive props to SeekingRaven for funding this story. U da best, Dawg.

A person who from childhood did not know what it was to "walk" and "move his hands" falls into an ordinary sick boy born in the middle of the XIX century. But such an ordinary one?

Hahah, no, I get thrown into hell with my ass handed to me along with the seemingly impossible task of actually saving the world. Let’s see just how long my second life lasts.  Hit me up at https://www.patreon.com/ReidR41n *Thank you LordValmar for the awesome cover artwork!*
