Ayumi is a character from the special Cilan and Brock! Gyarados' Outrage!!
Ayumi was a trainer, who received Pikachu. However, due to not being trained very well, Pikachu felt ill. Cilan and Brock examined Pikachu, so Cilan sent Stunfisk to let Pikachu train a bit. Ayumi had Pikachu learn Thunderbolt and execute it. Later, Ayumi went home, but saw a Gyarados on a rampage and came back to the Pokémon Center to tell Brock about it.
