Gammamon (Ghost Game)

Gammamon is the partner Digimon of Hiro Amanokawa in Digimon Ghost Game, and his form is its main antagonist.

Description
Gammamon is a Digimon that ended up with Hiro Amanokawa through his father, Hokuto Amanokawa. Brimming with curiosity, he has a habit of trying to bite everything. Despite being mischievous, he obediently listens to what Hiro and the others say. His favorite food is chocolate, going as far as calling it "Champion".

Compared to Angoramon and Jellymon, Gammamon's nature is more like that of a young child. He often uses descriptive words for food and often mispronounced certain phrases such as Trick and Treat as "Turkey and Treatment". This goes in line with him taking on the role of Hiro's younger brother. Despite his young demeanor, Gammamon can muster up the courage to confront challenges and think on the same level as his friends.

Gammamon's past is shrouded in mystery, when attempted to erase his existence from the past, the little traveler was shown to be confused as to what BetelGammamon was.

Except for Hokuto Amanokawa, Gammamon refers to any human by simply the first two in their names, like "Kiyo" for Kiyoshiro Higashimitarai or "Kota" for Kotaro Nomura.

is a Digimon known as the "Dark Conqueror" and is the source of Gulus Realm Burst. At some point he became Gammamon, a child-like Digimon that doesn't remember being GulusGammamon, through unspecified means. Gammamon eventually met Hokuto Amanokawa, who made him a scarf from his jacket's sleeve. During his time with Hokuto, GulusGammamon left some GRB through the in order to contaminate the world and create an army, with both Gammamon and Hokuto unaware of this..

On October 8 of Hiro Amanokawa's first year at Hazakura Private Academy, Gammamon is delivered to Hiro by, surprising the boy. A recorded hologram message from Hokuto explains to Hiro about and the, and asks Hiro to take care of Gammamon as a little brother. After Hiro manages to materialize Gammamon with the Digivice -V-, the two are attacked by, who wants to steal Hiro's time. Gammamon fights Clockmon, guiding him to a nearby park. Clockmon tries to steal Gammamon's time, causing a dark sillhouette to appear above him. Hiro figures out how to use Clockmon's power against himself and saves Gammamon. Hiro's determination to help his new brother causes them to synchronize through the Digivice, allowing the boy to call Gammamon's attacks. They defeat Clockmon, returning all the stolen time to its owners. Clockmon runs away, leaving Gammamon amazed by the power he received from Hiro.

The group confronts, who refuses to let them see his master. BetelGammamon digivolves to Siriusmon and fights BloomLordmon, who eventually detects GulusGammamon inside him. Overpowered, he reverts to Gammamon and is psychically terrorized by GulusGammamon, who takes over the body just as BloomLordmon is about to deal the final blow. GulusGammamon digivolves to and reveals the truth about Gulus Realm Burst, while also claiming Gammamon is gone. Regulusmon is able to fight back against BloomLordmon but is still not strong enough to defeat him. Hiro, realizing Gammamon can still be saved, tricks Regulusmon by pretending to synchronize with him, allowing Canoweissmon to fight him over control of the body. The conflict causes the group and BloomLordmon to be transported to Gammamon's inner world, where Canoweissmon and Regulusmon split.

Canoweissmon digivolves to Siriusmon and fights Regulusmon alongside Diarbbitmon and Amphimon. Enraged, Regulusmon fight back and nearly beat Siriusmon by using "Iphigenia Pierce". Siriusmon, however, came back and beat Regulusmon with his digivolution forms, de-digivolving him back into GulusGammamon due to Hiro. He then devours GulusGammamon because they are the same Digimon and makes peace with him. GulusGammamon briefly takes over control of Gammamon's body to reveal that he's originally from another planet that was destroyed by an evil entity that GulusGammamon identifies as The Endbringer. GulusGammamon had built his army to devour this entity which will be coming to devour Earth in roughly 2,000 years of human time.
