Real Master Martial Artist (Black Heaven and Earth Style and Nine Arts): As the holder of the title Goomoonryong and the head practitioner of the Black Heaven and Earth Technique, Chun-Woo is one of the most powerful martial artists of his time. His power is known and revered by many people both outside and inside the Murim-in, including all but one master shown so far. He can kick a motorcycle moving at high speed, causing the rider to loose control and crash. He is effortlessly capable of taking on 10+ bikers on their motorcycles. He is capable of containing all of his Simgichehon in his movements. In doing so he can destroy all of his opponents determination. Such a blow can break large boulder with ease. He has proven himself able to do battle with the Martial Arts Alliance alone, single-handedly killing and maiming many masters and elites, one after the other. After fighting four Munjus and numerous elites, suffering from Ki depletion, a broken arm, and being shot, Chun-Woo fought and killed two more Munjus, fought and subdued So-Chun Hyuk and his three protectors, dispatched the Alliance Chief, and did battle with Kang-Sung. Later on in the New Waves Chun-Woo was able to easily overpowered Kang-Sung once he rendered the former's Tai Chi Reflection Technique useless by sending him off the ground. Chun-Woo also held his own and nearly killed Jae-Kyu Kwon of the Ten Grandmasters of Murim, who admitted that his skills and the rumor, about him were true, if it weren't for Shi-Woon's intervention (albeit the elder was severely injured from his fight with Jae-gal thus had the use of only his left arm and his ki network was ruptured by the S.U.C.'s bomb). After that Chun-Woo fought both another one of the Ten Grand Masters, Ju Sang-Sik and Kang-Sung and manged to hold himself against them, thought it should be noted that the Grand Master was weakened from using too much Ki to heal Kang-Sung who was still recovering from his critical injuries. Even when it was seemed he was being pushed back by his former disciple, Shi-Woon who went through the Overhaul Rebirth, which was said would make him reach a level beyond Chun-Woo and became the strongest in the Murim, while using the Black Origin Threshold, though it should be noted that he was not fighting seriously, he easily managed to subdue him by breaking both arms and legs. According to Kang-Sung Chun-Woo reached the level of the Ghostly Doctor which mean that his level is that of one of the Ten Grand Masters of the Murim.
Immense Agility: Due to the natural strengthening of his body from years of Ki circulation Chun-Woo has supernatural Agility. He is agile enough to fall from a height of 4-5 stories while holding Shi-Woon and still land on the ground safely. While he and Shi-Woon were safe the car they landed on was destroyed. He has also shown a superman-esque ability to leap tall buildings in a single bound and doing so while one of his legs is hurt. Lastly, he has also show the ability to effortlessly flip and jump around a fight using most surfaces. He is able to dodge three bullet from Jung Lae Won and attack without him noticings him coming.

Black Origin Threshold: This technique is the height of skill for the Black Heaven and Earth Technique. Chun-Woo used it against the entire Martial Arts Federation once he was backed into a corner and saw Shi-Ho killed. Its not known exactly if Chun-Woo purposefully initiated this technique or if it is a result of getting lost in rage, but either way Chun-Woo was essentially invincible while using it as he had already been thoroughly beaten and tired out not to mention being shot. Even with these injuries he managed to take on some of the most powerful fighters the Murim had to offer including the genius So-Chun Hyuk and Sammoonryong. The only thing that eventually stopped him was his beloved disciple pleading with him to stop. It was said that while using the Black Origin Threshold he lost all of his martial form and attacked more like a wild animal
