Horus, Transmigrating Across the Heavens, Starting with Naruto

I am Horus Lupercal. Perhaps you call me a traitor, the sinner who set half the galaxy ablaze, the First Son erased by his own father. But I prefer another title: Warmaster. When I died aboard the Vengeful Spirit, a higher-dimensional being called “Paradise” gave me a second chance. The price was that I had to fight my way through this multiverse. Looking at these ninjas before me, making hand signs, breathing fire, and shouting about bonds and dreams, I can only laugh. No tactics, no discipline, just laughable individual heroism. You call this war? No, it’s nothing but child’s play. I may have no power armor, no Space Marine Legions, and only a mortal body and a rusted steel pipe. But I will teach you. I will turn the refugees in these ruins into war machines that make the heavens tremble. With cold-blooded schemes and ruthless force, I will crush your laughable ninja way. For the sake of resurrecting Sanguinius, I don’t mind burning down another universe.
