Noa's Raichu works as a waiter on Melemele Island with its partner Noa where they serve Alola Pancakes as the specialty. It won the annual Pokémon Pancake Race the year before Ash arrived on the island. Raichu is an Alola Form and is an Electric/Psychic type. It is able to hop aboard its own tail, use psychic power to lift the tail and move about while riding it.
Noa spent some time after lunch helping
Ash Ketchum and
Ash's Pikachu learn the rules to the race. Raichu got competitive with Pikachu and they became rivals during the practicing. Noa and Riachu then entered the race and ended up tying for second with Ash and Pikachu. Noa told her Raichu that they could enter the race again next year which cheered it up.
None of Raichu's moves were revealed in the episode.
