AG160: Harley Rides Again
Prior to Harley Rides Again
Harley's Octillery was the first member of Harley's team that managed to defeat May in a Pokemon Contest.
Octillery appeared in
Harley Rides Again, where Harley used it to win the Wisteria Town Contest. Octillery battled May's Munchlax and had the advantage until Munchlax used Metronome to summon a Thunder attack which caused severe damage to the Water type. However Octillery healed itself with Rest and defeated Munchlax with Octazooka.
Octillery also appeared in
AG160: Harley Rides Again, where it was used in Harley's appeal. During the appeal it was revealed to have learned Fire Blast, an attack that could not normally be used by Water types.
