A gritty, muscular Santa Claus stands tall in the snowy wilderness, his thick white beard braided into viking-style twists and his hair flowing, his piercing eyes locked in fierce determination. He wears a sleeveless, battle-worn red jacket with fur trim, showcasing his powerful arms, and a heavy leather belt filled with pouches for action. On the opposite side, a monstrous version of the Grinch, with sharp teeth, glowing yellow eyes, and a twisted, menacing grin, prepares to strike. His green fur is matted and wild, his claws ready for combat. The air crackles with tension, like a showdown in a fighting game. The snow glows softly under the moonlight, framing this epic battle between strength and darkness, as Santa stands resolute, ready to protect the spirit of Christmas.
