A Turtle of massive size with an ancient appearance, Maturin existed long before the creation of the mainstream universe in Stephen King's novels. By nature, Maturin was kind, wise, loving, gentle, compassionate, benevolent, and had a very grandfather-like demeanor when he spoke to humans. Maturin was said to be constantly withdrawn into his shell, sleeping and rarely ever coming out for anything. One of the occasions that Maturin did come out of his shell was when he had a stomachache which caused him to vomit out the mainstream universe, after which he promptly retreated back into his shell. Because of that, It considered the Turtle to be old, lazy, and stupid. However, given his vast amount of wisdom, power, and the aid, Maturin provided to those in need of it, It's perceptions of him seemed to be false.
