The following section contains information from StarCraft: Retribution.

Thakras is a powerful defiler.


It served or led a Brood whose name is unknown, attacking Jenson Archimedes's science facility in an effort to acquire the Argus Stone. The assault failed. Thakras and many minions were captured by the terrans, and many were used in scientific experiments.

Another zerg force entered the same installation, intent on rescuing the stone. Cerebrate Zargil instructed them to rescue Thakras, as it had powers which would help in acquiring the Stone.

Thakras was rescued, and used its Plague powers to reveal and sicken ghosts who were the Stone's final defenders. The ghosts were slain, and the Stone was acquired for the Swarm.[1]
