The Thunder Demon Straw Hat Luffy

This is a story where Luffy ate the Rumble-Rumble fruit, a Logia class devil fruit, and became a lightning man instead of a rubber man. Luffy also showed signs of Haki at a young age so Shanks decided to take him with them to train Luffy. Godlike Luffy! More serious/smart Luffy who acts more like a captain.
