Blue Merevy is the deuteragonist of the Menagerie trilogy.
Blue was first introduced in book one while he and Zoe were looking for the missing griffin cubs. He lied to Logan about what he and Zoe were looking for. Later, when Logan shows up at the Mengerie, Blue does not seemed surprised to find him there or by his ability to speak to griffin cubs. Blue was one of the people who helped Zoe and Logan track down the griffin cubs who were missing. He also helped get them out of the Sterlings' Mansion. He does not seem too admit that his dad is the king of the mermaid kingdom, making him a prince.
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 mermaid 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 afriad of Pyrosalamanders.
