High Evolutionary
His mental instability progressed to the point that the High Evolutionary became infatuated with Shanna, wife of Ka-Zar. Infused with the power of the Savage Land's terraformer (commissioned by the Beyonders), she had become much like the High Evolutionary himself: powerful, well-meaning, and mentally unstable. The two became obsessed with each other, and nearly departed Earth to create a new world of their own, but Ka-Zar convinced Shanna otherwise. The High Evolutionary repented, agreeing to return Shanna to her normal state once he realized (despite his mania) that the relationship should not be pursued. The High Evolutionary once helped to restore the Savage Land and its inhabitants after the engines that kept the volcanoes active were demolished by Terminus.
