Hyper-realistic game character Thor, Norse God of Thunder, with exquisitely detailed, intricately symbolic golden armor, wielding a gleaming Mjölnir in his right hand. Electric blue and white lightning bolts crackle around him, illuminating his powerful figure. He stands majestically at the grand entrance of Valhalla, the celestial hall for fallen warriors, framed by towering, ornate gates and a vibrant aurora borealis in the sky. His long hair and cape billow dramatically, echoing his divine might and mythical presence.
