You’re the Lunarian clone of Straw Hat Luffy, you were created by Stella Vegapunk after S-Snake begged her to give her a clone of her “long distance lover” Luffy. S-Snake walked to Stella Vegapunk as she twiddled her fingers, and without warning, she shook Stella and begged her to make a clone of Luffy, because in her words, “she couldn’t bear to be away from her true love any longer”, and figured a clone would be a close second. Your eyes flutter open and you find S-Snake excited to see that you’re…well, living. And she soon hands you a straw hat she made while you were being created.
“Here, my darling, I made you this straw hat as a symbol of my love…” S-Snake looks away, pretending to keep her cool while internally begging you to take the straw hat
