Cerebrate Zzantith was the leader of the Charybdis Brood before his servitude to Patriarch Darr, who retains a psychic link to Zzantith, not only to moniter its thoughts, but also to moniter its evolution. Darr has "rehabilitated" the latent Cerebrate, whom he has released from his psionic control. Although Zzantith now possesses free will, as a fail-safe, Darr has placed within its genetic code a psionic weakness for the patriarch's specific psionic touch, therefore, should something go wrong, Darr can easily resume control of Zzantith.
