Darkest Day

The Darkest Day (Japanese: ブラックナイト Black Night) is a black storm that covered the Galar region 3,000 years prior to the events of Pokémon Sword and Shield. During the course of the story, Rose deliberately causes another occurrence in an ill-advised effort to replenish Galar's Dynamax energy.
==History==
3,000 years ago, when attempted to stay alive by absorbing Galar's energy, it caused a red light to appear. This resulted in the Darkest Day. This phenomenon, in the form of a black storm, caused Pokémon to Dynamax and Gigantamax. However, they went berserk in the process, almost destroying the region. The event ended when Eternatus was defeated by , , and two youths.
In the present day, Rose aims to use Eternatus to bring about a second Darkest Day above Hammerlocke Stadium to avert the Dynamax energy shortage predicted to happen after a thousand years. Sonia has also conducted research into the Darkest Day. She learns that the event was connected to one Pokémon and that the two heroes of Galar were not humans, but rather Pokémon.
Rose awakens Eternatus during the time the and Leon are about to have their Championship Match. However, he could not control it, so Eternatus caused the Darkest Day to happen again, affecting all the in the region. When the player defeats Eternatus for the first time, it absorbs all of the energy in Galar to achieve its Eternamax state, further speeding up the Darkest Day. The player and Hop then bring out the Rusted Sword and Rusted Shield with the hopes of stopping Eternatus. This results in Zacian and Zamazenta awakening and coming to their aid. The four work together to defeat Eternatus in a Max Raid Battle before the player it, thus putting an end to the second Darkest Day.

========
The Darkest Day was first mentioned in Watch Out!! Strong Rivals, where Sonia told and about it.
In Glittering!! The Tapestry in the Vault, Sonia and Henry examined the tapestries in the Hammerlocke vault, depicting the events of the Darkest Day.
In Unbelievable!! The Shocking Truth, Sonia told Leon how she had found out that Chairman Rose had teamed up with Sordward and Shielbert, their intention being to start a new Darkest Day.
In Rumble!! The Horrific Darkest Day, once Leon had relayed Sonia's discoveries to the Galar Gym Leaders, they, along with Henry, Casey, Hop, Marnie, and Bede, decided to confront Chairman Rose at Rose Tower regarding this information. However, Rose wasn't at the tower, instead contacting the s through a giant screen from the Hammerlocke Stadium Energy Plant. He had originally intended to wait for the Champion Cup to begin before starting the Darkest Day, so that he'd have all of Galar's attention, but due to the circumstances having unexpectedly changed, he chose to start the cataclysm immediately. As such, around the region started to react, and multiple Pokémon around Galar began to Dynamax uncontrollably. Soon afterwards, was sighted in Hammerlocke, as it perched itself atop the Hammerlocke Stadium's tallest tower. Meanwhile, stationed around Galar started fighting against the rampaging Dynamax Pokémon to keep them in check.
In Shock!! Chairman Rose's Plan, Sordward and Shielbert confronted Eternatus atop Hammerlocke Stadium, but their Pokémon failed to defeat it, and the Rusted Sword and Shield they had stolen from Slumbering Weald a year earlier didn't do anything, forcing Rose to battle Eternatus himself, only to be defeated as well. In Splash!! The Return of the Two Pokémon, the Gym Leaders who had come to Hammerlocke started fighting Eternatus. Meanwhile, the Rusted Sword and Shield were retrieved by Casey's and and given to Henry to be repaired. While the Gym Leaders seemed to be able to defeat Eternatus, the pressure it exuded didn't lessen, and moments later, it transformed into its more powerful form. At the same time, Henry realized, to his horror, that he was unable to repair the artifacts.
Eternamax Eternatus proceeded to defeat the Gym Leaders, but the tide of the battle changed when and appeared, having woken up in Slumbering Weald in response of the start of the Darkest Day. His mind warped by Eternatus's poison, Henry refused to give the artifacts to the legendary heroes, even as they started to be pulled towards Eternatus. In Oh My!! The Disappearance of Henry, Zacian and Zamazenta attacked Eternatus with , resulting in a bright burst of light. When it faded, the Legendary Pokémon, the artifacts, and Henry had all disappeared. Following this, Rose turned himself in and resigned as the Chairman of the Galar League.
In PASS39, while on , Marnie spotted the sky darkening again, indicating that Eternatus had reappeared and the Darkest Day had restarted. This time, however, the cataclysm was more widespread than before, causing Dynamax Pokémon to also appear on the Isle of Armor and at the Crown Tundra. In the next chapter, at the Crown Shrine, the appearance of a Gigantamax and a Gigantamax temporarily interrupted 's reunion with its steed, , but both of them were eventually defeated by Peony, while Calyrex defeated a group of Dynamax Pokémon at Freezington. Elsewhere in Galar, Leon and the Galar Gym Leaders set out to protect the people of Galar from the cataclysm once more.
In PASS41, the heroes returned to the Galar mainland and returned the Rusted Sword and Shield to Zacian and Zamazenta, allowing the two to transform into their . In the next chapter, three Gigantamax Pokémon were revealed to have gathered at Hammerlocke to protect Eternatus, forcing Henry, Casey, and Marvin to defeat them first with their own Gigantamax Pokémon. Afterwards, Bede's Gigantamax forced Eternatus down from the clouds, allowing Zacian and Zamazenta to confront it once more. They ultimately succeeded in defeating it by following Henry's advice and striking it at its blind spot with and , reverting Eternatus to its usual form and ending the Darkest Day once and for all.
