Generate an image of Odin, the Thunder God from the "Final Fantasy" series, standing in front of a mottled city wall. He is clad in golden armor, wearing a winged helmet, and wielding a massive sword of thunder and lightning. Beside him is his loyal companion, the eight-legged black horse Sleipnir. The background is filled with tumultuous dark clouds and flashes of lightning, signifying the impending wrath of thunder.
