Known Sphere Builders

Sphere Builder Test Subject

File:Sphere Builder Test Subject.jpg

A test subject found by Enterprise.

The Test Subject Alien was a being from another dimension. The Sphere Builders sent him as an experiment to determine what effects the Alpha Quardant would have on him.

The Enterprise retrieves a pod inside a spatial anomaly. Inside an alien is dying. After being beamed to sickbay, the alien claims that he was a prisoner who was forced to volunteer for the experiment. Captain Jonathan Archer refuses to let him return to his ship, and when Phlox is distracted in sickbay, the alien attacks him and escapes by moving through the ship. After he is recaptured by Lieutenant Malcolm Reed and Major Hayes, the alien informs Archer that when the Xindi destroy Earth, his people will take over our universe. (ENT: "Harbinger")

Sphere Builder "Woman"

A Sphere Builder "woman" as she appeared aboard Degra's ship in 2154.

This Sphere Builder Woman appeared on Dolim's ship to urge the Reptillians to press their attack on Earth and release the superweapon. The Builders promised the Reptilians that they would rule as the dominant species of a new Xindi empire, if they hijacked the superweapon and attacked Earth.

Sphere Builder Presage

Sphere Builder Presage.

The Sphere Builder Presage would assist the reptillians in their attempt to deploy the superweapon in order to destroy Earth. Archer with the assistance of the other Xindi species were closing in on the reptillian vessel and the superweapon in an attempt to destroy it. The presage along with the other sphere builders would create spatial anomalies to allow the reptillians to escape.

Sphere Builder Primary

Sphere Builder Primary.

The Sphere Builder Primary coordinated the effort to assistance the reptillian in deploying the superweapon against earth, so her species could reconfigure space so they could take over the Alpha Quadrant. The Builders possessed technology which allows them to examine alternate timelines and therefore see possible futures. She knew that her species could be stopped by the humans. That why her and her kind informed the Xindi that they would be the victims of a genocidal attack from Humans in the 26th century, and should attack Earth with a prototype superweapon. However, the crew of Enterprise succeeded stopping their plan by disabling the main sphere and destroying the superweapon. The Sphere Builder Primary along with other of her species who were still on Enterprise when the sphere and anomaly collapsed appeared to die, screaming as they disintegrated back into their own realm.

Interestingly, all the leadership and military roles by the Sphere Builders to date were portrayed by the females only (aside from the one apparently male test subject), a move intended to highlight the "alienness" of the Builders by suggesting an androgynous appearance. A similar trick had already been used with the Talosians from Star Trek: The Original Series, along with the female changeling from DS9.
