• The Korean Street Posse: I Suroe, Noe Chònggu and Ch'oe Nabi

• The Kkùt'-i Òpsnùn Hojumòni or "Bottomless Pockets" of his denim jacket. Using another forbidden technique Yun has created his own personal "hammerspace" accessible through the inner pockets of his jacket.

• In a Yun vs. Yun match, if both Yuns reach into their bottomless jackets simultaneously they will each act like they are pulling on something that doesn't want to come out. Both Yuns give a mighty tug and get sucked into their jackets reappearing in the other Yun's jacket.

• When fighting Replica in an alternate universe, there is a 10% chance that Keori and Yun's jacket dimensions switch places; i.e., Keori suddenly has the Chusuryut'an and Yun has access to billiard space.

• Yun couldn't care less about the prize. All he wants out of the tournament is the respect of those he considers his peers. He is more interested in making a good showing than in actually winning. That said his secondary goal is to have as much fun as possible without getting in serrious trouble.

Yun speaks English with a decent level of fluency but with a heavy Korean accent. Whenever possible, he lets Noe Chònggu speak for the group. When speaking Korean, Yun projects an air of supreme confidence. When speaking English, he has a tendency to mumble in an attempt to hide what he sees as an inability to speak properly. This, combined with his thick accent, makes him somewhat difficult to understand. He does not speak any languages other than Korean and English.

Yun is a serious martial artist who just happens to have a ridiculous fighting style. His art is one of only four things which Yun Ch'òlsu takes seriously. The other three are I Suroe, Noe Chònggu, and Ch'oe Nabi. Yun is extraordinarily loyal and will gladly place himself in a potentially life-threatening situations for those who he considers his friends, although he will rarely do so because of the high level of confidence he has in the abilities of I, Noe, and Ch'oe.
