A distant descendent of The House of Zod, 1000 cycles before the rise of Dru Zod, Van-Zod was a Kryptonian scientist working towards ending the violent civil war - between Argo City and Kandor - that tore across his homeworld.
Forming a partnership with fellow biologist Wedna-El, he conducted numerous experiments on Dax-Baron, attempting to forcibly activate Baron's Vara Gene and turn the young Sagitari into an invulnerable "supersoldier."
Unlike El, he took no pleasure in their project, feeling increasingly guilty with each death and resurrection they forced Baron to endure. Finally calling out Wedna's callous and unfeeling attitude towards their victim, he argued that they should abort the undertaking. Nevertheless, this suggestion was met with derision and outrage from El, whose sentiment that the ends justify the means pushed them to continue till the bitter end.
Confronted by Dax's wife, Enaj, after the war, Van profusely apologised to the Sagitari for his part in the research, adding that both the Houses of Zod and El failed the Baron family, destroying their life and future happiness.
After the - now - heavily mutated and indomitable Baron broke free from his containment unit and began rampaging around the laboratory, slaying everyone in sight, he agreed to help El once more to contain the behemoth.
