They have recently come out of hiding during the last two decades with the reemergence of their kingdom and the NEW Crystal Princess "Cadence". - Dragons dont have much care for pony magic, but due to their overlap in the hidden Crystal pony settlements, some did mix with the Crystal pony population.

Rainbow Dash Jr

Full bred Pegasus - There are some Pegasus families that take their lineage VERY seriously, and seek to make even faster, stronger children. Rainbow Dash is from a "legacy family", from which they had the original pony to complete the "rainboom". Rainbow Dash is the first in CENTURIES to successfully complete the rainboom. - Pegasi have to have A LOT of magic to complete a rainboom, and thus Rainbow Dash is an extremely powerful magic user, but without any way to conduct said magic, this leads to a lot of accidents and misfires.
