Although it is not known when exactly the first Decapathon game released, the series has been around since at least the mid-2000s, as Todd Chavez became addicted to the game while he was in high school.
As of 2014, the most recent game in the series is Decapathon VII, which was released shortly before the events of Zoës and Zeldas.
- In Zoës and Zeldas it was revealed at one point a movie adaptation of Decapathon was planned.
- BoJack Horseman was considered for the role of Dr. Decapitator, but the part ended up going to Robert Downy Sr. It is not clear whether the movie was finished and released, or if the project fell apart somewhere mid-production.
- It is not known whether the character of "Dr. Decapitator" exists in the Decapathon games or if the character was made up for the movie, as the games themselves seem to have very little plot to base a movie off of.
