Judge O is a bit shorter than the rest of the Judges, and has a wiry frame and is mainly seen wearing the Judge's uniform. He has white, shoulder length hair and dark colored skin. O states that his skin color is the result of being burnt and his hair color being bleached by Chang-Sik's flames. His original complexion and hair color has yet to be known.
Seventeen years after the events of RagnarÖk, O has cut his fringe diagonally. Other than this, he appears much like he did before.
Judge O has a very calm and composed personality and can be happily perky, as opposed to Judge Q's rash behavior or Judge R's irritability. He is often the one who must step between the two Judges from fighting at the wrong time.
He seems to be prideful of being a Judge and was very angry on hearing about Announcer Shim being killed by Drake McDonald, going as far to swear revenge. He is also somewhat afraid/ traumatized of Yu Mi-Ra after seeing her mercilessly dislocate the necks of all the thugs attacking her.
Judge O later went to Yu Mi-Ra school and found her beating up thugs ruthless, O invite Mi-Ra to the God Of High School Tournament but refuse to make eye contact due to his fear of her. When all the Judges were at the tournament to oversee the fight, Judge Q and Judge R end up almost having a fight, but 0 got between them and told them if they don't act nice, he will not be quite which got both Judge to stay cool while 0 mention that Mi-Ra is the true monster. O later followed Q and R were they about to have a fight.
O report this to their boss Park Mu-Bong to which his boss order him to stop the fight to which O respond that he wouldn't do it since his duty is off unless he pay him more. Mu-Bong later came and punish the Judge, even O for disrespecting him.
Judge O has the ability to control fire and use it for combat in various ways. According to Q, he is the strongest Judge and despite having his ups and downs if he fights seriously no other Judge can defeat him. As part of his charyeok he is usually seen manipulating fire.
Superhuman Stamina: Judge O recall fighting Changsik for Seven days and nights straight, resulting in his hair and skin burnt by Changsik's flames, exhibiting incredible stamina and Endurance.
swordsmanship: In a fight with Jang Ho-Sik he recall fighting Changsik. In the flashback He's shown with medieval armor and a large broadsword, hinting a skill in swordsmanship before he become a charyeok user. He also used Dragon Slayer Sword whenever he is not directly using Red Dragon.
Judge O's charyeok manifest in ability to summons and commands Dragons. Usually he fought the Dragons to submission first, earning the Dragon's respect.
Red Dragon: Judge O's first Dragon. she's a large dragon with its size as close to a large multistory building. Even powerful NOX bishops such as Romario and Excaliose pay close attention to this dragon when engaging in battle.
In addition, he has several little dragons as well, likely offsprings of the two.
- Fire Manipulation: The dragons gives O the ability to create and manipulate fire at will.
- Regeneration: The most mature dragon, Red Dragon and Black Dragon, has a very high regenerative ability
- Polymorph: Two of his most mature dragons has the ability to transform into a humanoid form or a hybrid between humanoid and true dragon form.
- Dragon Slayer Sword: After summoning the Dragon, O punches it and breaks one of its fangs. He uses this fang to form a blade made of flames. The flame is strong enough to shield himself from an energy blast made by priest Saturn using her National Treasure gun.
- Protective Barrier: O can put up a protective barrier to limit damage to his surroundings.
- Breath Attack: A very powerful attack; O has stated that its damage is too great and that his own barrier cannot withstand it.
- Judge O's charyeok, Changsik, is a reference to the main character from an older manhwa, Dragon's Son Changsik. Youngje is known to be good friends with the author.
