Very little is known about the being Pn'zo, as a matter of fact is unclear if the name Pn'zo referrers to the being or its race. It appears to be an android being of some kind. Pn'zo was captured by the
Shi'ar while attempting to rob a bank, he was imprisoned on Kr'kn. After taking control of the mighty Shi'ar, the maniacal autocrat
Vulcan sought to create an Imperial Guard of killers that were loyal to him only. He informed the Guardsmen
Nightside and
Oracle to bring him a list of prisoners imprisoned on Kr'kn. Pn'zo was one of the five beings to be offered freedom from prison to serve on the new Guard. Pn'zo would be joined in its mission by
ZZZXX a member of an unknown
symbiote race. A nameless survivor of the
Uncreated invasion and
Xenith, a once heroic warrior now sought to bring vengeance down upon the head of her cousin Kallark. Last but certainly not least is
Hodinn, who once served on the Guard before
Cassandra Nova, although it seems that now it only wants to burn. Their first mission was to kill Vulcan's brother
Havok and the
Starjammers.
