James's Mareanie (Japanese: コジロウのヒドイデ Kojirō's Hidoide) is the first Pokémon that James caught in the Alola region, and his thirteenth overall.


Mareanie and James
Mareanie and her former crush

Prior to being caught by James, she had a crush on a differently colored Mareanie after he saved her from a Tentacruel.

Mareanie first appeared in The Sun, the Scare, the Secret Lair!, in which she encountered James when he was wearing a scuba diving helmet resembling a Corsola. She latched onto his helmet, mistaking it for a real Corsola, causing it to crack and flood with water. After James reunited with Team Rocket, Mareanie latched onto his head and injected him with poison which caused him to resemble a Mareanie, causing Mareanie to become smitten with James. Later, during a battle with Ash, Mareanie jumped in to help Team Rocket and launched a Spike Cannon towards Pikachu. With Mareanie's help, Team Rocket gained the upperhand against Ash, poisoning his Rowlet and dealing serious damage to Pikachu. As Jessie's Mimikyu was about to launch one final attack, Bewear suddenly appeared from the water and took Team Rocket away with her. After being dropped off at Bewear's den, James asked Mareanie to join his team, which she accepted. After catching her, James called her back out, and Mareanie affectionately latched onto his head, making him look like a Mareanie once more.

In A Team-on-Team Tussle!, Mareanie assisted Team Rocket in their quest to obtain a Darkinium Z. She battled a Totem Alolan Raticate, which protected the Z-Crystal. Mareanie attacked with Spike Cannon, agitating it to follow them away from the Darkinium Z. She was then quickly defeated by Raticate's powerful attacks.

In SM058, Mareanie was reunited with her former crush, which fought James for her affections. She ran away from Team Rocket and found sanctuary with Ash at Professor Kukui's house. The next morning, while walking along the beach, she was attacked by another Tentacruel, but she was saved by James.

Personality and characteristics

Mareanie fantasizing marrying James

Similar to a number of other Pokémon James has owned, such as Victreebel, Cacnea, and Carnivine, Mareanie is very fond of James and occasionally engulfs her Trainer's head in her ten spiked tentacles. The resulting poisoning causes James to look like a Mareanie. Mareanie has an attraction to James's appearance in this state, one of the reasons she decided to join him. In addition, Mareanie is shown to be a romantic, as seen in SM055 where she was drawn to the sound of Professor Kukui and Burnet's wedding, causing her to fantasize about marrying James, only to be snapped out of her delusion by her Trainer calling out to her. However, prior to the moment when she first poisoned James, she was shown to be quite grumpy, as shown when she slapped Jessie's hand away when Jessie first stroked her.

When James attempted to capture a female Frillish in SM058, Mareanie saw her as a rival for his affections and scared her away with Spike Cannon to prevent this capture. She then cried when James scolded her for doing so.
