Megamorphs is a series of books within the Animorphs franchise, created by K.A. Applegate. These stories feature the same group of characters who can transform into animals, but each book is told from the perspective of a different character. This allows readers to experience the adventures and challenges faced by the Animorphs from various viewpoints. The Megamorphs books are unique because they often explore larger themes and more complex plots than the main series. They provide deeper insights into the characters' thoughts and feelings, making them a popular choice for fans of the Animorphs universe.
