Thardus, AKA Project Titan, was a failed Space Pirate bioweapon created by their research teams on Tallon IV. It is a being of animated Phazon-bearing rocks, though how it gained basic intelligence or how it was brought to life is a mystery. Physically, it is similar to the Gerignak presumably due to convergent evolution.

Thardus was created early in the Space Pirate operations on Tallon by the research teams at the Phendrana Drifts. As the pirate reports would indicate, Thardus had broken free of their control and was deemed a failure, leading to its imprisonment in a reinforced containment area near the research station. It was later found by Samus Aran, who confronted the monster and acquired the Spider Ball from its remains.

  • According to interviews with one of the modelers for Metroid Prime, Thardus' concept was directly inspired by a movie monster; most likely the Gerignak.
