One of the notable aspects of Guardians of the Galaxy Vol. 2 is its character development. The film delves deeper into the backstories of the characters, particularly Star-Lord, Gamora, and Drax, providing a more nuanced understanding of their motivations and emotional arcs. The introduction of new characters, such as Ego and Mantis (Pom Klementieff), adds depth to the narrative, exploring themes of identity, family, and belonging.
