Spider’s dad in Avatar: The Way of Water is Colonel Miles Quaritch , the main human villain from the original Avatar movie.

Who Spider Is

Spider (Miles “Spider” Socorro) is a human boy who grows up among the Na’vi on Pandora instead of returning to Earth as an infant.

He is taken in and raised by Jake Sully and Neytiri’s family, making him part of the Sully household even though he is not Na’vi by blood.

His Biological Parents

In the films and tie‑in material, Spider’s biological father is Colonel Miles Quaritch , and his mother is an RDA pilot named Paz Socorro.

Paz dies during the human–Na’vi conflict, and Spider is too young to be sent back to Earth, which is why he ends up being raised on Pandora instead.

Quaritch and Spider’s Relationship

When Quaritch returns in an Avatar body in The Way of Water , he discovers Spider is his son and starts using that connection to track and pressure Jake Sully.

Their bond is tense and conflicted: Quaritch is responsible for terrible acts against the Na’vi, but Spider still ends up saving his life, hinting at a complicated future between them in later sequels.
