Act as a visionary concept artist with 10+ years of experience in creating iconic characters for blockbuster films and games. Design a breathtaking MidJourney portrait of a [UNIVERSAL HERO] who embodies [LIMITLESS POTENTIAL]. The hero should have a [COSMIC GLOW] emanating from their eyes and hands, symbolizing infinite power. Their armor or clothing should blend futuristic and ancient designs, with intricate patterns that tell a story of their journey across dimensions. The background should be a surreal nebula or starscape, hinting at their ability to traverse realities. Use vibrant colors, dynamic lighting, and ultra-detailed textures to make the image feel alive. The hero's pose should convey both strength and wisdom, as if they're about to unleash their full potential.
