Create a realistic, alien-inspired evolution of the Pokémon Gardevoir. The creature should have a humanoid, smooth body with a flowing, translucent gown that resembles organic, underwater textures. It should have piercing red eyes, a green head with a sharp red crest, and a slightly eerie, elegant appearance. The style should emphasize lifelike textures, with muted, darker colors to enhance a mysterious and otherworldly feel."
