Seeker (The Fountains of Forever)

The Seeker was an an artificial intelligence serving Anubis. She controlled a pyramid-shaped spaceship and could create a mummy-like body for herself. The Seeker called herself and Dorothy Bell the sisters of Osiris, the last two of many.

During Anubis's millennia-long sleep, the Seeker has been tasked with seeking all remaining Osiran devices. The non-sentient devices were to be destroyed. Her last assignment before waking Anubis was to find the last sentient Osiran device, the Architect's great key and deliver her to Anubis. When the Seeker detected the energy signatures of Dorothy, who had merged with the key, she left Anubis's ship the Shining Horizon, travelled to Earth and tried to find the key. By mistake she transmatted to her ship Hanif, Erik Ulfriksson, the Tenth Doctor, Cleopatra Hunsicker and Cindy Wu instead of Dorothy, who camouflaged herself from the Seeker. She then transmitted an ultimatum to all Earth primates. She would destroy the planet, unless the Architect's great key was delivered to her. Dorothy saved the planet by voluntarily uncloaking herself and agreeing to surrender. The Seeker transported her and Gabby Gonzalez to her ship. Deeming all but the Doctor and Cindy to be potentially of value to the historical records, the Seeker transmatted the two back to Earth and, with the rest departed to Anubis's ship, Shining Horizon, where she woke Anubis from hibernation. From that time on, she followed Anubis's orders. (COMIC: Spiral Staircase)
