When it comes to ages, eras we have characters who fit in and those who are a little off and I think based on agenda people will put characters in different generations. The three generations mostly referred to are:
Old Gen
- WB, Roger, Ray, Garp, Sengoku, Rocks
Mid Gen
- Shanks, Mihawk, BB, Akainu, Aokiji, Dragon
New Gen
- Luffy, Zoro, Kid, Law, Sabo, Coby, Yamato, Loki
But this leaves some characters who are between these generations like Kaido. You can put BM in same gen as WB (she was 6 years younger) but putting Kaido in same gen as WB/Roger seems weird because the age gap is bigger (15 years). And if you put Kaido in the Old Gen then you should put Kizaru in the Old gen too since he and Kaido are almost same age (1 year difference). And if you put Kizaru in Old Gen then you should put his brother Akainu (3 years younger) also there as well as Dragon (same age as Akainu) but then we have Garp and Dragon ending up in same gen.
The way I see it it would be better to put Kaido in Mid Gen but then we have him 19-20 years older than BB and Shanks. Which is super weird because the age difference between Shanks and Kaido/Kizaru is almost the same as the age difference between Shanks and Luffy. Shanks is actually 9 years younger than Katakuri and age difference between Kata and Yamato is 20 years.
Should we add a new gen to the ranks to cater for these inbetweeners?
