Unnamed Trainer(M01)

Other than Corey, Fergus, and Neesha, a female fourth Trainer takes off from the pier on the back of a Fearow. She is seen flying Fearow while Fergus and Neesha ride their Gyarados and Dewgong. She likely never made it to New Island, unlike the others.
 * This Trainer and her Fearow are often mistaken as a continuity error involving Corey and his Pidgeot.
 * She is the only character who leaves for New Island but never appears again. Mewtwo wipes the memories of everyone on New Island and transports them back to the mainland (except for Team Rocket), but this Trainer completely disappears.
