Welcome to the SDG Timelines, the site all about BB Senshi. As I don't really know how to read japanese there may be not much info here but I will try my best to provide pictures and as much info from other sources.
I had divided the SD Gundams into their respective teams and stories, in each of the team pages you will find pictures and text about the stories and characters.
It is really diffucult to set the foundation so there is still much time to wait before the site is complete.
This site does not cover the early knight series and the Genzo series.
