In one of the last story arcs of Thor vs Zarrko, Zarrko's plot was revealed to be a plan to save humanity. In his future, Thor, had separated from his human self, Jake Olson, and lost his ability to understand humanity. Because of this, Thor became more and more oppressive and imposing, and believed that ruling humanity was the only just thing to do. Zarrko knew that in his future, Thor would become a tyrant, so he had to travel back in time and stop him before the Odin Force made him invincible and near-omnipotent.
