Zell-Ex
From superman.nu: Supermanica
Zell-Ex
Father of Kull-Ex and a gifted inventor from Kandor on the planet Krypton. Zell-Ex develops designs for a multi-purpose transportation device, but his plans and blueprints are literally blown away by a strong gale. When Jor-El patents a similar vehicle at a later date, Zell-Ex believes it is theft, and his anger over the act is passed on to his son, even after Kandor resides in the Fortress of Solitude. (S No. 134/I-III, Jan 1960: "The Super Menace of Metroplis!"; "The Revenge Against Jor-El!"; "The Duel of the Supermen!")
