Create an image of a warrior eagle with black and purple plumage

Create an image of a warrior eagle with black and purple plumage. The eagle must be in a majestic and imposing pose, with wings partially open and claws ready to strike, conveying a sense of power and determination. The background of the image should be a contrast that highlights the colors of the eagle.. It can be a dramatic sky at dawn or dusk, with dark tones and clouds that accentuate the brightness of the eagle's black and purple plumage. Lighting should focus on the eagle, highlighting its details and vibrant colors, while the background is more subtle, but complements the eagle's dominant presence.
