Protagonist

The Protagonist (also known as Sara) is the player character of Child of Eden. They are an antivirus program who is tasked with purifying the computer network Eden after it is infected (possibly by the Hacker) as part of a self-espionage mission, and rescuing Lumi, who has been held captive. They wield the Lock-On Laser and theTracer.

Appearance
The Protagonist is not seen physically in Child of Eden, except for their hands. However, they possibly appear on the cover art to the game. From there, we see the Protagonist is a blue humanoid figure with short dark blue or black hair and they are wearing a white shirt. They have broad shoulders.

Trivia

 * The Protagonist's true gender is unknown. Sara is a feminine name, but it is unofficial. The figure on the Child of Eden's cover art shows a masculine-like body, but it could be female.
 * The Protagonist's alternative name Sara is an unofficial name. The name was taken from the co-host of Toonami on Cartoon Network, who reviewed the original Rez in 2004. Since the review featured a cameo by Swayzak from Trapped in Hyperspace, who gave the protagonist of Rez his nickname, it's only natural that the protagonist of Child of Eden would be nicknamed after the other character in the review.
 * It is unknown what happens to the Protagonist and why they did not try to repel the Hacker's attack on the K-Project in the events of Rez. It's possible they forgot about Eden by that time.
