Chronologycal order of movies and TV episodes which can view as or at least not interfere with canon.
- Bardock stories as the first has mentioned in the main series and the other as it's sequel
- Dragon Ball obviously
- Dead Zone as it has been referenced in Z
- Dragon Ball Z and Kai with mixed order followed up Caleus's list on reddit. Shortened events from Kai, but filler episodes from Z. Caleus heavily recommends stopping halfway through episode 95 of Z if you want to save the SSJ transformation for Kai. Though Kai has somewhat censored pictures. Episodes 170 and 171 of Z are takes place halfway through episode 85 of Kai, that I can not indicate with this list. If you want to skip the fillers just go along with Kai. If you choose to watch fillers with Z prepare for repeated events. I am watching with Z episodes as create this list but personally think fillers rather annoying, so I'm with Kai.
