Generate a hyper-realistic and powerful depiction of a fusion between Jack-8 from Tekken 8 and Raiden from Mortal Kombat in a dark, stormy setting. The character should be colossal, with Jack-8's metallic, armored build merged with Raiden's mystical elements, including lightning-infused details and glowing blue eyes. The fusion should have mechanical arms with embedded lightning emitters, and an aura of electric energy radiating from the body. The background should be a thunderous sky filled with dark clouds, lightning strikes, and silhouettes of shattered ruins, creating an ominous and electrifying atmosphere.
