Men's Luffy's Gear 5 Thunder-Splitter Black Oversized T-Shirt

 "Luffy's Gear 5 Thunder-Splitter"

This design focuses on the epic moment of Luffy's Gear 5 transformation. It would be a large, high-resolution graphic printed on the back.

• Front: A small, simple graphic on the left chest. This could be the Straw Hat Pirates Jolly Roger in a distressed, minimalist white print, or just the word "Wanted" above a bounty value like $3,000,000,000.

• Back: A detailed, dynamic illustration of Luffy in his Gear 5 form, mid-attack. The design should capture the surreal, cartoon-like aesthetic of this transformation. Think wavy lines, a stylized thundercloud, and a flash of white lightning that splits the composition. The lightning bolt could be a vibrant, stark white, while Luffy is depicted in a monochromatic or limited color palette (shades of grey and white) to make the white pop. The sheer size of the graphic on the back of an oversized shirt will make it feel powerful and significant.
