Create a detailed, human-sized ocean guardian mech standing powerfully in an underwater setting. The mech should have a sleek, streamlined design, primarily in shades of blue, with intricate armor details inspired by oceanic motifs like waves and coral patterns. It holds a large, ornate trident, symbolizing its role as a protector of the seas. Incorporate glowing aqua accents to highlight its power and make it blend naturally with the ocean background. The lighting should feel like it's underwater, with soft rays filtering through the water, giving the mech a mystical and ethereal presence.
