Hyper-realistic game character Thor, the God of Thunder, depicted with incredibly detailed, symbolically intricate armor in vibrant hues, holding Mjölnir in his right hand. Lightning crackles and dances around him, highlighting his fierce expression and powerful stance. He stands majestically at the grand entrance of Valhalla, the sky swirling with storm clouds above, casting a mythic aura over the scene. The ancient doors of Valhalla, engraved with Norse runes and adorned with legendary motifs, frame Thor, as a soft glow emanates from within, suggesting a realm of gods beyond.
