Lewis's Gothorita lives with
Lewis on Milos Island in the Unova region and is one of his partners.
Lewis explained to
Ash Ketchum and his friends that according to the Milos Island legend, the Pokémon which helped Landlos was a Gothimiru.
Lewis's Gothorita was out looking for a Revival Herb for
Lewis as normally
Lewis's Lilligant would do the searching but it was ill at the time.
Lewis introduced
Ash Ketchum and his friends and
Lewis's Gothorita grew fond of
Iris' Axew.
Rainmaking Ritual
Lewis knew the rainmaking ritual that was supposed to produce rain on Milos Island. He took bundles of grass to Landlos' shrine and lined them up. He lit the grass with two rocks and he explained to everyone that once the grass was burning, they'd tell Landlos their feelings through
Lewis's Gothorita so Landlos would bless them with rain on Milos Island so the land would be fertile again and the Revival Herbs would grow. The ritual that
Lewis's Gothorita helped performed seemed to work until Tornelos interfered with it.
Medium Ritual
Lewis's Gothorita also played a large role in the Medium Ritual as it was able to use its powers to convey
Iris' feelings to Landlos to summon it.
It tried to help out battling against the legendary Pokémon Tornelos and Voltolos but its attacks weren't powerful enough to do any damage to them. It was able to give the Revival Herb to Landlos to heal it just like the legend of Milos Island said and
Lewis's Gothorita was the one who lent power to it.
