"Design a character living in a zombie apocalypse, wearing old, battered military armor and a weathered helmet. His armor, once protective, is now scratched, dented, and covered in dirt, with some plates missing or loosely held together with straps and makeshift repairs. His military helmet is dented and scuffed, with a cracked visor or exposed lining. His clothes beneath the armor are torn, grimy, and patched, showing signs of long- term survival in harsh conditions. He stands in a simple, neutral pose, looking forward with a tough, determined expression. The color scheme should include muted, earthy tones of browns, dark greens, and grays, emphasizing his worn, post- apocalyptic look. No background to keep the focus on the character. "
