Inclusion of the Original Dragon in future Pokemon titles
Ever since Pokemon BW, there's been talk about the Original Dragon, the one before the split into Reshiram, Zekrom and Kyurem occurred. This has been expanded in BW2, but it remained an empty plot point.
We believe that needs to be changed, which is why we want to ask GameFreak to include it into future installments. It could be used to continue Primal Pokemon or implement an upgrade to the DNA Splicers, which were introduced in BW2.
