iron_man, hulkbuster, character: hulk. A full dynamic full body shot of an epic battle between Iron Man in the Hulkbuster armor and the Hulk. Iron Man in the massive red and gold Hulkbuster power armor stands facing the viewer at a low angle, arms braced. The suit is bulky with oversized hydraulic arms, heavy reinforced plating, and multiple glowing arc reactors on the chest and limbs. The helmet's visor reveals Tony Stark's face with a focused yet strained expression. The Hulk is locked in a contest of strength directly in front of the mech, towering and savage with intense yellow-green eyes and gritted teeth, his green skin and huge muscles straining powerfully. His torn purple pants show the power of his transformation, with bulging veins visible. Both of their massive fists slam together, with shockwaves, sparks, and flying debris emanating from the impact as cracks spiral across the ground. In the distance are the ruined remains of a military base, dark smoking wreckage, massive craters, and a stormy, cloudy sky streaked with lightning and red emergency lights. During the ultimate test of strength, sparks fly between the adversaries.
