Attack on Titan Eren wallpaper, dark epic style, with Eren Yeager at the center flanked by Mikasa and Armin on either side, the Founding Titan's skeleton looming above, surrounded by the Attack Titan and the War Hammer Titan on each side, a green energy column piercing through the body at the bottom, dominated by black and gray with accents of ghostly green eye light and energy effects, the splashed ink texture complemented by a flock of crows flying over a doomsday wasteland.
