Tropica City is the location where series 2 of Yu-Gi-Oh! BAM is set.
Further down the line, you'll be able to visit Tropica City, a new setting that has yet to be unveiled. In Tropica City, you'll be able to learn more about the Organizer, a being that was briefly teased about in the previous chapters. You'll also be introduced to the Channelers, ancient beings of tremendous power.
