Ancient hero

The ancient hero (Japanese: 古代の英雄 Ancient Hero) is a character from the backstory of Pokémon Legends: Arceus.

In the core series games

Pokémon Legends: Arceus

The ancient hero, long before the Diamond and Pearl Clans ever arrived, had befriend a group of ten Pokémon, who were the ancestors of the Noble Pokémon: Kleavor, Lilligant, Arcanine, Electrode, and Avalugg, and of Hisui's Ride Pokémon: Wyrdeer, Ursaluna, Basculegion, Sneasler, and Braviary.

In the Old Verses, it is implied that the hero was part of the Celestica people. Legends say that he, along with his ten companions, soon started to seek out all of Arceus's Plates to meet the deity himself. After finally finding them all, he managed to meet and battle Arceus, defeating it and receiving not only the being's respect, but a blessing given to all of the hero's Pokémon: that not only them but their descendants would keep Arceus' blessing and would be worshipped by the people of Hisui as the hero himself, would be remembered as the greatest Pokémon wielder of all.

Statues of all of his partners were built at the Temple of Sinnoh, until during the battle between Dialga and Palkia, where all the statues, along with a majority of the temple was destroyed. The remains of the ruined temple later became Spear Pillar
