Alfred Zerdan commands the Kilna, Mars colonists driven from their world by catastrophic atmospheric loss. He spearheads their aggressive campaign to retake a recovered Earth, seizing the space station Atlantis as his invasion base. Strategically, Alfred equips his forces with scaled-down technology derived from the forbidden Titan project. His tactical operations feature deploying the prototype weapon Marine Kaizer against Earth's Northern Knights, aiming to crush resistance while field-testing its power. This deployment inadvertently reawakens the dormant titan Z-Knight, altering the conflict. Alfred harbors complex political motives; knowing Kilna's nobles intend to discard him after conquering Earth, he secretly develops Marine Kaizer as his personal safeguard against their planned betrayal. His command choices directly trigger ancient war machines' resurgence and escalate hostilities between Kilna and Earth's defenders.
