A highly detailed realistic tattoo design for the shoulder to elbow, depicting a virile and powerful Templar knight in full medieval armor, wearing a classic Templar helmet (grand heaume with a cross motif), dynamically lunging forward with sword raised to strike a menacing evil dragon embodying omnipresent malice. The dragon rears up aggressively, breathing fire or clawing back, in a fierce combat scene full of tension and opposition between good and evil. The knight is bathed in a resplendissant spiritual aura with a glowing Templar cross, incorporating subtle fleur-de-lis symbols on the armor or swirling in the background. Style: realistic with dark medieval influences and trash polka elements like bold ink splatters in black and red, high contrast, intricate textures on armor and dragon scales. Color palette: black, gray, deep red for accents and fire, gold or white for the aura. Emphasize dynamic movement, dramatic poses, and intense confrontat See more
