Marcellus is a trainer that wanted to compete for the Whirl Cup, which is why he asked help to get his Remoraid trained. Misty battled using her Corsola, enough to get Remoraid evolved into Octillery. Though he lost, Marcellus was surprised that the other Remoraid at his house did not accept Octillery. Team Rocket stole Remoraid, though Octillery tried to free them, proving it is their friend. After the heroes intervened, the Remoraid were freed and evolved into Octillery as well.
