Marvin (Japanese: マナブ Manabu) is a character in the Pokémon Adventures manga.

In the manga

Pokémon Adventures

Marvin debuted in Wow!! That's One Big Pokémon. He had recently moved to Galar and noted how different the local Zigzagoon looked compared to where he was from. He was surprised by a giant Pangoro and wandered into a campsite, where he encountered Henry Sword, Casey Shield, and Professor Magnolia, learning that the giant Pangoro had just been a simulation used by Casey to research Dynamax.

Wanting to teach Marvin about what Dynamaxing is, Henry and Casey allowed the boy to participate in another simulation. Henry lent his Sirfetch'd to use since Marvin had no Pokémon of his own. Together, the trio fought the Dynamax Pangoro hologram, eventually defeating it. Having experienced a Pokémon battle for the first time, Marvin gained the confidence to set out on his own Pokémon journey. After asking and receiving approval from his parents, Marvin joined Henry and others on their quest to study Dynamax.

In Chomp!! Defeat Drednaw, the trailer house was attacked by a trio of wild Drednaw. In order to battle the Bite Pokémon, Henry and Casey each received a Rotom Phone with a Pokédex function installed, officially making them both Pokédex holders. With some assistance from Sobble, the Drednaw were defeated. Afterward, Professor Magnolia suggested Marvin keep Sobble, which he happily accepted and later nicknamed Sniffler.

In Toasty!! Battle Against Toxapex, Marvin helped Henry train for his upcoming Gym battle with Nessa. Marvin eventually called off the battle, but Henry's Twiggy gained enough experience to evolve into a Thwackey. Afterward, Marvin and Casey went to Hulbury Stadium, where they watched Henry's battle with Nessa.

In PASS16, Marvin and Henry trained together in preparation for the latter's Gym battle with Opal. While they sparred, Sniffler evolved into a Drizzile, giving Henry the idea to use its water bombs and devise a strategy for avoiding Opal's Gigantamax Alcremie's attacks. The training proved to be a success, allowing Henry to win the battle.

In PASS18, the group traveled to Route 9 Tunnel, where several people had reported seeing Pokémon Dynamaxing despite it not being a Power Spot. There, they found a wild Dracovish under attack by several Trainers under orders to either catch or get rid of it. With quick thinking and Sniffler's tears, Marvin kept the Trainers distracted long enough for him to catch Dracovish and escape. At Henry and Casey's suggestion, he decided to keep Dracovish and nicknamed it Uonon.

Sniffler (Japanese: ナミダくん Namida-kun) is Marvin's first known Pokémon. As a Sobble, it took a liking to Marvin as they traveled together and happily accepted when he asked it to join his team. It later evolved into a Drizzile while helping Henry prepare for his fifth Gym battle.

Debut Wow!! That's One Big Pokémon
Uonon (Japanese: ウオのん Uonon) is Marvin's second known Pokémon. Something caused it to Dynamax at the Route 9 Tunnel, sending it into a berserk rampage from shock. Several Macro Cosmos employees were sent to cover up the mess by either catching or getting rid of Dracovish, but it was saved at the last second by Marvin and Sniffler.

None of Uonon's moves are known.
