Tarren wears a blue sleeved top, dungarees with pink patches, and a brown hat with a white bobble. His cheeks contain two oval-shaped freckles, similar to Tombo Tillbitty of Yu-Gi-Oh! ZEXAL. He is shorter than fellow orphaned children Amanda and Frank.
Tarren is a better navigator than Amanda and Frank, offering this skill to help Yuya Sakaki get to the Duel Palace through the Commons alleyways without running into mobs. Tarren is also somewhat curious. This leads him into trouble twice; first when the orphans tried to sneak into the Duel Palace in a disguise, and second when, while watching the Friendship Cup Turbo Duel between Crow Hogan and Shay Obsidian, he ends up clinging onto Crow's Duel Monsters and had to be rescued by Shay.
Tarren first appeared with Frank at a Topsiders' square witnessing Dennis McField's magic show. Tarren was awed, but Frank told him to hurry along. They were then seen hiding behind a bush, and witnessed Yugo and Zuzu Boyle outside of a restaurant trying to warn passers-by of an invasion. Frank and Tarren popped out to steal food from a tray at the restaurant. When they returned to Crow's house, they were promptly scolded by Crow. Tarren then saw Yuya Sakaki and Celina, mistaking them for Yugo and Zuzu. Later on, Frank and Tarren had a practice duel when they learned that Sylvio Sawatari and Celina went out on their own. While the kids enjoyed their meal with Riley Akaba, the kids witnessed Crow and Yuya arguing over whether a smile or a full stomach was more important. Crow tried to drag them into the argument, but the kids refused to comment, and they later watched Crow and Yuya Duel. Tarren appeared to be impressed at Yuya's Pendulum Summon. Unfortunately, Sector Security arrived, having followed Celina and Sylvio back to Crow's house, and they arrested Yuya, Sylvio, Crow, Shinji, and Celina, but let the kids off.
The kids snuck into the Duel Palace in order to watch Crow's Duel in the Friendship Cup against Gong Strong, but the disguise that they used fell apart as soon as they got in, forcing them to evade Palace security the entire time and causing Crow to worry about them during the Duel. They cheered Crow on as he defeated Gong, and quickly fled the palace. At some point, he, Amanda and Tarren watched the Duel between Shay Obsidian and Dennis, where he developed a dislike for Shay due to his brutal tactics.
Friendship Cup Finals
The kids later found Zuzu in the Commons after her brutal loss to Sergey Volkov. They brought her to an overpass to see Crow and Shay's Duel, as they couldn't sneak into the Duel Palace again and the matches were now taking place on the duel lanes around New Domino City.  During the duel, Tarren went missing, only to be spotted hanging off "Raikiri's" back. Tarren could not hang on for too long, and was sent flying; Shay flew on his "Raidraptor - Revolution Falcon" to catch him and bring him back to where Frank, Amanda and Zuzu were.  After the duel, the kids and Zuzu were cornered by Sector Security officers tasked to capture Zuzu; fortunately they were rescued by Sora Perse, and the three children were awed by Sora and Zuzu's Tag Duel and impressed when they learned Sora had saved her. The three children learned about the invasion of the Obelisk Force when Moon Shadow arrived. Amanda, Frank, and Tarren were dismayed to learn from Moon that they also had to go with Zuzu and hide in the Underground Labor Facility.
During their time in the Underground, they learned about the strange abilities of Zuzu's bracelet, which they found strange and fascinating. The three children had to tirelessly dissuade and physically prevent Zuzu from leaving the Underground several times because of her concern for Yuya. Zuzu eventually slipped away after Shay and Shinji started rioting, and the kids frantically began to search for her after they realized she escaped, and quickly alerted Gong, Chojiro Tokumatsu, and Crow.
After escaping the Underground, the three children convened with Crow in an alleyway. Amanda had to talk Tarren and Frank down a few times, as Crow warned them to beware of anyone suspicious, and Amanda reminded them that they didn't have Duel Disks, so they wouldn't be able to take on their enemies. They split up from Crow to begin searching for Yuya, Zuzu, Celina, and Sora. They reunited with Yuya, Gong, and Sam during Yuya's attempt to get back to the Duel Palace. Amanda, Frank and Tarren were shocked and saddened to hear of Celina's recapture by the Obelisk Force and, with Tarren leading, led Yuya to another pathway to the Duel Palace. He, Amanda, Frank and Sam also ended up traveling on Shay's two "Raidraptor - Force Strix", flying over New Domino City for the first time in their lives.. They stayed behind to watch the Friendship Cup Final between Yuya Sakaki and Jack Atlas..
Amanda, Frank, Tarren, Sam, and Chojiro witnessed the appearance of a massive dragon in a dimensional rift. They later witnessed Jack and Crow each take on Z-ARC, the Duelist controlling the dragon, and their subsequent defeats and that of Declan Akaba, before Z-ARC was finally defeated by Riley Akaba.
After Z-ARC's defeat, Tarren is seen watching Yuya's Duel against Jack with Shinji, Damon, Tony, Frank, Amanda, Sam, Chojiro, and his lackeys. He cheered with Frank when Yuya won and watched Yuya and Declan's Action Duel. Tarren watched Yuya and Declan gather Action Cards to in order for one of them to win the Duel first due to the effect of "Performapal Five-Rainbow Magician". He was happy when Yuya won and was sent to the Pendulum Dimension by Ray Akaba to witness her revival as Zuzu and was surprised by Rin's spirit reviving as well.
