I'll start with classic Dragon Ball, then DBZ, and finally DBS. This is my opinion after reading the entire manga and watching all the classic and current anime. I came to a conclusion about how many seasons each arc could be adapted into. Some are long, so I had to divide them into 2 or 3 seasons. Classic DB:
Pilaf arc, season 1 (10 episodes)
21st tournament arc, season 2 (14 episodes)
Red Ribbon Army arc (this is divided into 3 seasons due to its length)
Muscle Tower and General Blue arc, season 3 (14 episodes)
Tao Pai Pai and HQ arc, season 4 (8 episodes)
Baba tournament, season 5 (8 episodes) 22nd tournament arc, season 6 (12 episodes)
Piccolo Daimaō arc, season 7 (16 episodes) 23rd tournament arc, season 8 (16 episodes).
In total, all of classic DB could be adapted into 6 or 7 seasons.
Now let's talk about DBZ.
Saiyan Saga Season 1 (26 episodes)
Frieza Saga (divided into 3 seasons)
Namek Saga Season 2 (18 episodes)
Ginyu Force Saga Season 3 (8 episodes) Final Battle Against Frieza Saga Season 4 (20 episodes)
Cell Saga (also divided into 3 seasons) Android Saga Season 5 (14 episodes)
Cell Development Saga Season 6 (16 episodes)
Cell Games Saga Season 7 (18 episodes) Majin Buu Saga (can also be divided into 3 seasons)
25th Tournament Saga Season 8 (20 episodes)
Fat Majin Buu Saga Season 9 (14 episodes) Super Buu and Kid Buu Saga Season 10 (20 episodes)
In total, all of DBZ could easily be 10 seasons. And now we go with Super DBS: DBS Beerus Season 1 (6 episodes)
DBS Resurrection of Frieza Season 2 (7 episodes)
Champa Tournament Arc Season 3 (12 episodes)
Black Arc Season 4 (20 episodes) Tournament of Power Arc (would be divided into 2 parts)
Part 1 Season 5 (22 episodes)
Part 2 and Tournament Finale Season 6 (22 episodes)
DBS Broly Season 7 (10 episodes)
Moro Saga (the Moro Saga could easily be divided into 3 arcs)
Galactic Patrol Arc and Namek Fight Season 8 (14 episodes)
Training and Earth Invasion Arc Season 9 (14 episodes)
Final Battle Against Moro and the Prisoners Season 10 (16 episodes)
Granola Saga (this one would only be divided into 2 seasons)
Granola Arc Season 11 (22 episodes)
Gas Arc Season 12 (14 episodes)
And finally the Superhero arc season 13 (26 episodes)
This is my format. Each season could have exclusive music with lyrics, or even an OVA or spinoff from the past. I'd also like them to have their own covers and a custom logo for each season, depending on the theme. What changes would you make? Would you add or remove episodes, and from which arcs? Would you combine any seasons or add more? Let me know in the comments.
