Light died, only to be violently thrust back to 2008, inheriting the ultimate burden: the complete, decade-long script for the Marvel Cinematic Universe, leading straight to the Snap.
He is not just a witness; he is a player. A powerful System resides within him, gradually unlocking the limitless power of a Kryptonian-but his abilities are currently restricted to weak, early-stage Tiers.
His first moral test arrives instantly with the disappearance of Tony Stark. Armed with perfect knowledge but cursed with a body that can barely survive a severe bruise, Light is forced to watch the crucial tragedies of Iron Man 1 unfold. He is a ghost with a global strategy, prioritizing his secret training and financial preparation over immediate, low-stakes rescues.
From the shadows of the Avengers Initiative to the rise of Ultron and the schism of Civil War, Light must race against the accelerating timeline, evolving from a powerless spectator to the single, decisive force capable of preparing Earth's heroes for the arrival of Thanos.
This is the story of the man who knew everything, and who must become strong enough to change the ending.

In Marvel With Unique Skill Great Sage
The void was absolute. No light. No sound. No air. Not even time itself dared to exist. It was a place of unyielding nothingness, where existence held no meaning, and the concept of life was a cruel joke. Within this void drifted a single, nameless soul. How long had it been there? Minutes? Centuries? The soul couldn't tell. Trapped in this purgatory, there was no sensation, no thought-only an endless, silent blackness. But then, something shifted. A sudden force, like a cosmic vacuum, gripped the soul. It had no time to react, no chance to resist as it was yanked violently from the void. Light-blinding, overwhelming light-burst into view for the first time in what felt like eternity. And then-CRASH! The soul, now encased in a physical form, plummeted from the heavens and smashed into the scorching sands of a desert.

The people of Asgard are looking for a new home. They get a warm welcome on Earth, except for Loki. He is treated like a criminal of war, a terrorist. All they see in him is darkness.

[...] Was great hun, well done to you." - @MistyB1989, from the United Kingdom. "This book was so good I can't even begin to describe how well written it was. Everything about was just so good. Thanks for blessing me with this book." - @allegedlyjasmin "Amazing book! Had me invested the entire book!" - @GLiTcH_GaMiNg, from Australia Fragment: At that moment, the door to the apartment swings open and a man barges in. He is holding something that looks like a big syringe in his hands. "Yoohoo... Reindeer games! You home? I've got something for you!" The man stops in his tracks when he spots us sitting on the couch. "I'm sorry, I didn't realise we had company. And beautiful company at that, I might say. What's your name, beautiful? Do you have clearance? Williams, does she have clearance?" [...] Tony Stark walks over to me and takes my hand, standing just a little closer than necessary. "Nice to meet you, mr Stark." I reply, taking my hand back gingerly. [...] From the corner of my eye I can see that Loki has turned his chair to face the room, watching the exchange between me and Tony Stark with a hint of a smile on his face. I get the sense that there's not much that gets past the Trickster. Mr. Stark has already moved on, walking towards Loki. He is holding up the syringe like it's a Super Soaker gun, waving it back and forth. "This will only hurt a little, Bambi!" Tony laughs. First published February 2018. Edited april 2018.

Blue Moon| Book 1 | An Avengers fan fiction series| *under editing*
Within twenty-four hours, thirteen year old Thea Fossil's life has been turned upside down. She arrives home late one night to find her astrophysicist mother dead, and she and her little sister are wounded by a mysterious poison from an unknown race of aliens called Imeldi. The next time she wakes up, she is in a SHIELD base, and is surrounded by a crowd of unusual characters that wary Thea has a hard time trusting, particularly when she has just been orphaned. There is Thor, the compassionate yet slightly intimidating Asgardian, but she considers him too eager to please. Natasha Romanoff and Clint Barton both are too shadowy and curt for Thea to put her faith in. Tony Stark, she finds humorous, but at times self-centered and bossy. Dr. Banner, Thea admires, but his own dangerous secret is known to her. And Steve Rogers is far too upbeat for Thea's generally pessimistic liking. And then there is one other person. Someone with a tongue of wit, a personality of iron, and a mind as complicated as Gordian's Knot- just like Thea. Someone who knows how to soothe her fears just as quickly as he knows how to get under her skin. The person that is perhaps the most untrustworthy, but whom little Thea may begin to trust the most. Loki. But even if Thea can begin to trust, and to work as a team, the threat of the Imeldi is still potent and long-fingered. Thea must learn to control her new powers, her temper, and her hidden fire if she wants to survive this. Particularly because the Imeldi want two things. Global revenge. And Thea. RATED PG-13: For interval language (d*mn, as*, h*ll) and violence.Complete
