"The Universe was almost destroyed once. The one who saved it was an old guy named Ultraman King. The Universe was like your body, on the verge of death. We Ultramen can fuse our bodies with someone to heal them. But the whole Universe... It was just too big. It wasn't destroyed, but Old Man King is now dispersed throughout the entire cosmos. You can call out to him, but there's no response."
- ―Zero as he recounted the events of Crisis Impact.
The Crisis Impact (クライシス・インパクト Kuraishisu Inpakuto) was an apocalyptic incident that happened nineteen years before the start of Ultraman Geed.
- Main article: Omega Armageddon
After Belial defeats Zero during the Omega Armageddon, Belial detonated the Super-dimensional Eradication Bomb with his Giga Battle Nizer, destroying Earth in the process. The great explosion created a black hole that consumed the entire universe. At the verge of getting destroyed, Ultraman King arrived and reversed the damage caused by Belial earlier on. King merged with the universe ever since but was left unresponsive. What happened to Belial and the Ultra Warriors were unknown but this event was remembered by the people of revived Planet Earth and was called the Crisis Impact.
Absent from Earth for many years, the Ultra Warriors became a popular legend, with records of their existence being mysteriously lost and the memories of them slowly fading from the collective consciousness of humanity. It is also known that many of Earth's inhabitants were led to believe Crisis Impact as a meteor shower until a recent discovery of Belial's caricature within an unearthed record.
Other races across the universe appeared to have knowledge of Crisis Impact despite the efforts of Ultraman King. In hopes of restoring the order that Belial destroyed, aliens of multiple races had founded AIB and station themselves on Earth. Kuruto, an Alien Shadow, revealed that his kind had started to explore the universe in search of a replacement planet, as the damage that Planet Shadow suffered during Crisis Impact terrified the Alien Shadow, who feared that the event would happen again.
Despite humanity largely forgetting about them, the Ultras had also survived the destruction and reconstruction of the Universe. On the Land of Light, Hikari's Ultra Capsules were stolen, forcing Zero to visit Earth and investigate the matters. Meanwhile, on Earth, another Ultraman had been already living on the planet for several years. Unaware of his actual self, the disguised Ultra would soon become the Earth's latest defender.
After the death of Belial by the hands of Geed, the wounds of the universe caused by the Crisis Impact had healed and Ultraman King's body has been restored as well.
- The Crisis Impact is based on the Unicron Singularity (ja:Grand Black Hole) from Transformers Cybertron (ja:Transformers Galaxy Force), most tellingly from its English adaptation. As shown, the destruction of a celestial body (Unicron's sun prison and Earth) caused the creation of a black hole that consumed other planets in existence before they were erased by godlike figures (Primus and Ultraman King).
