Parky's MMA debut was at Japan's MARS 5. Both he and Team MAD teammate Bae MyoungHo suffered losses that outing, but then launched into winning streaks securing spots in M-1. And that's where the similarity in the Legend FC Welterweight champion's and Parky's careers diverged.
Parky was given the opportunity to fight in DEEP, and he went on a tear. At DEEP 41st Impact, he shared the card with Tomoya Miyashita, Joe Taimanglo, Hiromitsu Kanehara, Kazuyuki Miyata, and Kazunori Kikuno who won the grand prix and captured the DEEP Lightweight belt. Parky faced Naoki Matsushita - an 8-year veteran of the JMMA scene with an impressive list of past opponents - and handed him his first 1st round loss in three years. In his next six fights, he continued the carnage and never saw a fight go to decision, or even out of the 1st round.
