Barret's Rebellion in Midgar

Create a dynamic RPG scene inspired by Final Fantasy VII, featuring Barret Wallace as the central figure. Depict him as a muscular man with a rugged demeanor, sporting a mechanical gun-arm that gleams under the neon lights of Midgar. His signature green tank top and cargo pants contrast with his dark skin, while his wild, spiky hair adds to his fierce appearance. Surround him with the gritty, industrial backdrop of Midgar’s slums, showcasing crumbling buildings and flickering holographic advertisements. Infuse the atmosphere with a sense of rebellion and urgency, capturing the essence of a world on the brink of chaos. Incorporate elements like a glowing Materia orb floating nearby and the distant silhouette of the Shinra Tower looming ominously. The mood should be intense and gritty, reflecting Barret's determination to fight against oppression.
