==In the core series games==
====Background====
In the past, Arceus created the Hisui region and possibly the world, and was worshiped as "almighty Sinnoh" by the ancient Sinnoh people, the Celestica, of whom Cogita and Volo claim to be descended from. At some point, it was said to have banished to the Distortion World for its violence.
After the Ancient hero of legend and his ten Pokémon companions successfully faced it in battle, Arceus gave its blessings to the hero's companions,Mai: "The Pokémon that graces Deertrack Heights is one of those honored few. It is directly descended from a Pokémon that was blessed with almighty Sinnoh’s protection." () which they used to protect the people and Pokémon of Hisui.Irida: "The ancestors of Kleavor, Wyrdeer, and their cohort drew on almighty Sinnoh’s own power to protect Pokémon and people alike—so it’s said. It’s by their grace that our clan—that any of us— still lives in vast Hisui today!" () These Pokémon's descendants would become the noble Pokémon and . Afterwards, Arceus returned to the Hall of Origin, and its Plates were scattered across Hisui.
Following the disappearance of the Celestica people from Hisui, a new group of settlers arrived from across the sea, who adopted the Celesticas' beliefs as their own. They would later become the rivaling Diamond Clan and Pearl Clan, who believed almighty Sinnoh to be either or respectively. The two clans came to believe that their counterparts worshiped a false god and went to war against each other, with the conflict only ending after both sides became too weak to continue fighting.
====Pokémon Legends: Arceus====
At the start of the game, Arceus calls out to the , from within a realm located outside both space and time. This realm is completely absent of anything other than golden rays of light. Arceus asks the player's appearance and name, and after they have done so, it will introduce the setting of the game, much like the opening intros made by professors from other titles. It then tells the player that they should seek out all Pokémon, and they will be able to find Arceus again.
The player character is then seen falling through empty space and loses their smartphone. Suddenly, Arceus, as a glowing white silhouette, appears before the player and transforms their smartphone into the Arc Phone. The player is later found unconscious on by Professor Laventon, having been sent back in time by Arceus. The player notices the Arc Phone on the ground nearby, and upon inspecting it, reads a message from Arceus: "Seek out all Pokémon." The Arc Phone will beep during certain points of the game, such as opening the caves to each of Hisui's three lakes, as a way for Arceus to help guide the player.
After the player has obtained all eighteen Plates, Arceus will transform the player's Celestica Flute into the Azure Flute at the Temple of Sinnoh. Upon playing it, if the player hasn't caught all Pokémon, they will be disappointed to see that nothing has happened. The Arc Phone then begins to beep, with Arceus again prompting the player to "Seek out all Pokémon."
Once the player has obtained at least one of every Pokémon in Hisui (except for Mythical Pokémon), the player can return to the Temple of Sinnoh and play the Azure Flute once more. This time, a glowing stairway appears, leading to the Hall of Origin. The player enters the area, seeing a large empty space. Arceus then appears and challenges the player to a battle. The Arc Phone becomes an infinite supply of Mysterious Balms. Like with the frenzied noble Pokémon, the player must hit Arceus with balms until the gauge fully depletes.
Once the player defeats Arceus, it will congratulate the player for successfully seeking out all Pokémon. Wishing to join the player on their journey, it will then grant them a part of itself that the player can use in their party, as well as giving the player the Legend Plate.
Later, when the player returns to the Temple of Sinnoh, the Arc Phone will beep. Arceus will allow the player to have a rematch with , (regardless of which one the player originally faced) or Arceus itself. 
After the player completes the Daybreak storyline and catching Arceus, it will call for the player's Arc Phone, requesting them to sleep in their home. In the player's dream, Arceus will reveal the Eternal Battle Reverie option for the player to test their skills and luck in a series of endless battles. The challenge ends when the player either loses or quits, and Arceus will leave behind various rewards based on the player's performance.
In all battles against Arceus, it will have the Legend Plate active, allowing it to change its type whenever it uses . During its first battle, it will have zero effort levels. In all other subsequent matches, it will have the full ten effort levels in all stats.
