On October 31, Gatchmon wears a pumpkin outfit.
- Deep Search: Launches one of its claws into a search engine to find the results of a search.
- Gatch Claw: Coats one of its claws in energy, then slashes the opponent.
Gatchmon is investigating Leviathan's actions when he is discovered and has to flee. Desperate to escape, he performs a search and finds Haru Shinkai, emerging from his smartphone. After explaining the concept of Appmon, Gatchmon declares Haru to be his Buddy, though Haru refuses. He begins to fade, however, having exhausted his personal power in the Real World. Haru's attention is then drawn by his mother, whose messaging app is on the fritz. Gatchmon reveals that a virus-infected Messemon is the cause. Messemon proceeds to reveal embarrassing images to world before fleeing into an AR-Field; Gatchmon and Haru give chase. Messemon attacks the pair, and Gatchmon calls on Haru to appliarise him, but Haru is too scared. Despite being in his weak chip form, Gatchmon defends Haru, telling him that he has confidence in him. Haru eventually decides that he does want to be a main character, unlocks his Appli Driver, and appliarises him.
Now at full strength, Gatchmon attempts to scan Messemon for a weakness, but the relentless attacks prevent him. Haru aids him with a keyword, allowing Gatchmon to perform a search and realize Messemon's weakness: that words can only do damage if you let them. Gatchmon uses this idea to simply ignore Messemon's attacks, allowing him to get close enough to attack and purge Messemon of the virus. The partnership cemented, the pair exit the AR-Field.
On October 8, Gatchmon joins Haru in searching for Ai Kashiki after navigation apps go on the fritz. During the search, Gatchmon tells Haru about his investigation into Leviathan and the L-Virus that causes Appmon to go out of control while also discovering that saying Leviathan's name causes him to freeze up. They come across a virus-infected Navimon, the cause of the problem, and chase him into an AR-Field. Navimon proves to be difficult and tricky, using his arrows as a basis for homing attacks. Haru's search allows Gatchmon to realize that rotation confounds the Navimon's location capabilities, and then Gatchmon teaches Haru how to perform an Applink. Haru applinks Messemon with Gatchmon, which allows him to use Messemon's trailing body to stymie Navimon. Gatchmon then defeats and purifies Navimon. They are attacked by Cameramon not long after, and Cameramon manages to blind Gatchmon. Haru gets the idea to applink Gatchmon with Navimon but accidentally perform an App Fusion, creating DoGatchmon. DoGatchmon forces Cameramon to flee with one attack.
On October 15 at school, Gatchmon tells Haru more about DoGatchmon, teaching him that, while most Appmon can Applink with each other, certain pairs of Appmon instead perform a fusion, combining and increasing in grade. He also mentions that it will take a while for DoGatchmon to be able to be appliarised, and he gets into an argument with Navimon over who contributed mroe to DoGatchmon. Yuujin calls for Haru afterward, and Gatchmon and Navimon hide while they leave. Gatchmon is present at Kashinoki Books when Ropuremon begins wrecking havoc on Fantasy Saga players at first and then the whole city later. He and Haru give chase, ending up back at school. An AR-Field exists, which has turned the school into a recreation of the Amusing! Exciting Dungeon video game. Gatchmon is frustrated with the subsequent dungeon crawl as he is the subject of its unfairness, though Haru greatly enjoys. At the end, they find a despondent Ropuremon who is angry that they used a walkthrough to make it to the end. Gatchmon tells him that it's impossible to clear the game without one, reading out forum states that call the game boring. This pushes Ropuremon's berserk button, and he grows into a huge size befitting a final boss. Haru attempts to appfuse DoGatchmon once more, but the fusion fails, forming the ineffectual Sukasimon instead; Haru attributes this to Gatchmon's and Navimon's discord. Sukasimon is easily defeated and unfuses, taking with him Gatchmon's energy. Right before Ropuremon can strike down Gatchmon, Haru tells Ropuremon that he honestly enjoyed his adventure. Seeing Haru's sincerity allows Ropuremon to purify himself of the L-Virus, and he surrenders his Appmon Chip while revealing himself to be a 7code Appmon. Haru obtains the Appmon 7code PAD in the process. Gatchmon believes that gathering all the 7code Appmon will unlock a power that will allow them to face Leviathan, so they make it their goal to obtain all seven.
On October 31, Gatchmon wants to partake in Halloween's bounty, namely sweets. Haru is absorbed in a book about artificial intelligence and refuses to leave despite Gatchmon's nagging. Eventually, Haru snaps that Gatchmon can head out alone, and so Gatchmon does so. Dressing up as a pumpkin, he goes trick-or-treating. A pair of girls finds him creepy-cute and happily give him sweets, which he greatly enjoys. Gatchmon eventually comes across Haru being harassed by Cameramon's Men in Black and rescues Haru's Appli Drive before he can be stolen. Haru flees with Gatchmon in hand and apologizes for his earlier behavior. Gatchmon waves it off, as their bond as Buddies is too strong for something small like that. They take the fight to Cameramon in an AR-Field, but Gatchmon admits surprise when Cameramon proves to be able to appfuse into Scorpmon, as he believed Haru's Appli Drive was unique. Scorpmon's strength requires DoGatchmon, and though Haru is initially hesitant due to Sukasimon's previous appearance, they manage to bring DoGatchmon forth. Scorpmon's power is strong and accurate, and he is able to snipe them unerringly no matter where they hid. Realiizing that Scorpmon is using the surveillance system to track then, Haru searches for the cameras' blindspots, which allows DoGatchmon to plot a path and sneak up on Scorpmon. DoGatchmon defeats Scorpmon in melee range, though Scorpmon's Appmon Chip is rescued by Mienumon. Gatchmon and Haru completely make up in the aftermath over sweets.
