Gammamon (Ghost Game)

Gammamon is the partner Digimon of Hiro Amanokawa in Digimon Ghost Game.

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.
