Create a full-length photorealistic image of a hybrid character combining Emma Frost's head, hairstyle, and facial features, while substituting her body for Marcus Fenix's physique. Modify Emma's iconic costume to fit this new muscular body. The background should blend elements representing both characters, incorporating a futuristic cityscape and a barren battlefield, fusing their distinct environments. The lighting should highlight the character's strong presence, emphasizing her confident stance. Aim for a dynamic composition that showcases the unique attributes of both characters while maintaining a cohesive look.
