Blue Merevy is the deuteragonist of the Menagerie trilogy.
He owns a pet kappa who lives in a fish tank in his room.
Blue has blond hair usually in his face, with a green tint, green eyes, and is very tall. Logan Wilde describes him as smelling like the sea, assuming that he surfed a lot. He has blueberry-colored scales when he is in merman form.
Blue is often portrayed as calm and collected. He is also said to be oblivious to the fact that many girls are crushing on him, including Jasmin Sterling. Blue is also deathly afraid of Pyrosalamanders.
