Dragon Ball Super is the latest installment in Akira Toriyama's signature shonen series. DBS is nearly a decade old, while the grander franchise is nearly four times as old. Each Dragon Ball series chronicles Goku's adventures as he grows stronger, defends the planet, and accomplishes incredible goals with other courageous heroes. Four decades of content means that Dragon Ball has a lot of lore to work through, which is largely consistent but still subject to scrutiny.
