Greystone wears a NAVY BLUE COLOR WITH YELLOW DETAILS, a combat uniform with the traditional X-Men symbol on the belt, and a tight-fitting suit with TWO PAIRS OF yellow stripes in a VERTICAL pattern, PARALLEL TO EACH OTHER IN THE TORSO AREA. His arms are large and defined, and he holds enormous steel chains or technological weapons in the midst of a scene of destruction. The background is a burning urban environment, with buildings collapsing, flames burning all around, smoke in the sky and metallic lightning bolts flying. REALISTIC digital painting art style stylized with oil or acrylic paint texture, inspired by Marvel Masterpieces / Upper Deck trading cards, with dramatic lighting, vibrant colors, deep shadows and energetic effects. 3:4 format, with the character highlighted in the center of the composition, in a combat pose, conveying raw power and chaos.
