Transmigrated into the dangerous Marvel Universe twenty-five years ago, Karl Smith survives as an ordinary wealthy man by utilizing a unique Sign-in System. While others seek immediate power, Karl makes the bold decision to accumulate his sign-in rewards for a quarter-century, enduring decades of normalcy while secretly investing in Stark Industries and Oscorp. Now, with the deadline finally arriving, he is threatened by the Kingpin, who demands his bar.

Just as danger looms, Karl's long wait pays off: he awakens as the Silver Age Superman, a being of limitless potential capable of sneezing stars away and surviving black holes. No longer needing to steal Spider-Man's origin or fear street-level villains, Karl stands atop the food chain. As he tests his god-like abilities in the vacuum of space, a new opportunity arises when an invitation to a mysterious Chat Group appears, connecting him to protagonists from other worlds.

Ready to reshape the Marvel timeline, the God of Earth prepares to face aliens, gods, and cosmic threats with absolute dominance.
