Cobra's past self emerged from an incident where he traveled to the Spring of Time to investigate the fading existence of his companion, the cyborg Armaroid Lady. During this investigation, an accidental temporal displacement sent him into the past. There, he encountered Princess Emeralda before her transformation into a cyborg—the very woman who would become the Armaroid Lady.

In this past timeline, Cobra became entangled in political conflicts and assassination plots orchestrated by Emeralda's adversaries. He fought these enemies relentlessly while striving to ensure Emeralda’s survival and safety, driven by the urgent need to prevent her erasure from existence.

This period unveiled a deeper emotional connection between Cobra and Emeralda, casting them as romantic partners—contrasting their typically professional or platonic dynamic elsewhere. Cobra displayed visible frustration and anguish over repeatedly losing women close to him, including witnessing the deaths of two innocent women. His fierce determination to protect Emeralda underscored profound emotional stakes rarely seen in his character.

Cobra's actions directly influenced Emeralda’s eventual transformation into the Armaroid Lady. He played a crucial role in events leading to her receiving her cybernetic body, thereby cementing their future partnership. This era also exposed Cobra’s vulnerability as he confronted the potential loss of his most enduring companion and grappled with the weight of his personal history.
