Iron Man Armor? I've Got Golden Armor and a God-Slaying Spear

[Marvel Comics + Invincible + System + Heroic Spirit Fusion] After transmigrating into the Marvel Comics universe for eighteen years, Luke's System awakened, making him invincible from the start! He began by merging with the Heroic Spirit Karna, clad in golden armor and wielding a god-slaying spear. Just as Tony Stark was losing hope, Luke descended from the sky and pierced Iron Monger with a single thrust, stunning the world! By taking part in the story, he could plunder the origins of the multiverse. From the Battle of New York to the Infinity War, he swept all opposition aside, personally erasing every regret. But this was only the beginning! The DC Universe, The Boys, Invincible, Fate, One-Punch Man... The Myriad Worlds were all his hunting grounds! When the Celestials, the creator gods, arrived to pass judgment on Earth, Luke stood in midair and pointed his spear at the heavens. "Judge me? As if you're fit to!"
