- Jörmungandr was a prolific warlord and tactician 1,000 - 4,000 years ago, causing him to be at war with his Kyogre and Groudon for control of the Hoenn region of the time. This was called the Weather Wars. Jörmungandr eventually won the war, forcing the Kyogre and Groudon to seclude themselves under the sea and inside the volcano for hundreds of years.
- After winning the war, Jörmungandr became a pacifist and became a professor and a scholar, focusing his research on the concepts of Infinity energy and alternate dimensions. He did this in hopes to find Heidi after her disappearance.
- When Ragnarök came, Jörmungandr (and Leifi) were successfully able to escape Freya’s wrath with the help of Palkia’s portals and the sacrifice of half of Leifi’s cores; however, Loki and Jörmungandr were separated during the escape, leading them to completely different dimensions. In Jörmungandr’s case, he landed and took refuge in Gaia, offering his assistance in return for a place to stay.
- Jörmungandr spent the past 100 years since Ragnarök researching Friede and her movements, while also attempting to find a backup plan to escape in case she ever found him. Thus, whenever he wasn’t needed, he spent time hidden from the rest of Morrigan’s pantheon, only befriending those he had to such as Lauren. However, Morrigan changed, and eventually committed herself to Freya’s cause. This put Jörmungandr’s status in jeopardy, as, if discovered, he would surely be destroyed before doing anything.
- Izanami eventually found Gaia and, in turn, was challenged by Morrigan herself. Her defiance against the Alpha piqued his interest, and, after they fought, Jörmungandr approached Izanami, requesting for her to take him with her. She agreed, luring him to Elysium and informing him about Heidi. He now lives in the Kanto region as a teacher to the local children and young adults.
