Zeromaru is the Partner Digimon of Yagami Taichi in Digimon Adventure V-Tamer 01.
Zeromaru is Taichi's first digimon, originating from his Digital Monster Ver. 1 v-pet. Taichi originally tried to enter the D-1 tournament with Zero, but found that his adult level wasn't a digimon programmed into the game and was disqualified. (under construction)
- ↑ Although never appeared in the manga, Koromon is the only evolution that Botamon has in the Digital Monster Ver. 1 v-pet.
