Going for a bit of a deep cut here! EvoL debuted in 2012 at the beginning of the 3rd gen with this absolute banger (which was unfortunately overshadowed bc of the amount of groups that debuted in this time period). It's iconic to me, though, and that's all that matters (well, that and SAAY managing to debut solo years later).
