Ja Wangnan

''"I will one day... be the king of this tower!" - ''Ja Wangnan assuring his resolve to climb The Tower

Ja Wangnan is the title and main protagonist of Tower of God: Part 2 - The Return of the Prince. He is an fairly unknown man, but aspires to be the next king, calling himself a prince, however whether or not Zahard is truly his father is unknown (based on his power he's likely only a self-proclaimed prince. It's still inconclusive if Repellista comment regarding the final return of the Prince of Zahard implied Ja Wangnan being the chosen one or if she meant Baam). He values his determination in life more than anyone else's desires. He plans to scale up The Tower's ranks and usurp his 'father's' position.

Part II
Ja Wangnan's first appearance has him being approved for the 20th Floor test, followed by him asking himself whether he should destroy everything, because he'll be king of the Tower. This was quickly followed by him failing due to being set on fire by a teammate. He then nurses his burns and claims revenge, until the loan shark, Kim Lurker comes to claim his money. Wangnan tries to flee but gets smacked into the ground and questioned about the test results. He gets offered one more chance at the 20th Floor test but this time if he fails the loan shark will harvest his organs. Then another Regular (Nya Nia) who failed the 20th Floor test at some point, comes to deliver his food, which the loan shark pays for claiming Wangnan will pay for it with his body later. Wangnan questions the Regular about why she's delivering food, before answering himself. He then states the difference between him and those up top, the Regular then leaves and gives him a coupon to use after the test, telling him it's a congratulations. Wangnan is very pleased by her and thinks to himself that he'll reward her with a restaurant. He then proceeds to retake the test only upon to find entrance an unknown figure standing in a room with filled with corpses.

Deciding that he didn't want to become a skeleton when he fails the test, he 'persuades' Baam to team up with him. He tries to make small talk but Baam stays quiet. 3 minutes later, Kang Horyang comes in and Wangnan rallys Baam to fight with him. He's intimidated by his size so he decides to team up with him as well. He knows that the next test will be harder with more competitors so he decides he must defeat the next person that comes in. The next one happens to be a young schoolgirl and Wangnan couldn't manage to kill her because she's wearing a uniform. The next person who comes in is a girl wearing glasses in which Wangnan is happy because she's not wearing a uniform. He was about to attack her until the schoolgirl yells out "Unni!". The schoolgirl calls her Goseng (meaning 'troubled') and the glasses girl calls the schoolgirl Miseng (meaning 'shorty'). With his life on the line and wondering if the competitors came here to play, Wangnan denounces everyone saying that it's a test and everyone should be fighting each other, much to the distress of the others. Hon Arkraptor enters and catches the attention of the large person and Ja Wangnan. Akraptor tells Wangnan it's useless to waste strength for nothing but he says that there are too many competitors. He has a vote to pick one off the team in where he chooses Miseng. Wangnan chooses the 'silver shithead' saying that the strongest one should be voted off first. Baam then rises and declares that he will drop everyone.

Baam begins fighting the stronger regulars., and Wangnan hopes that all three of them will kill each other at the same time. Goseng recognizes the symbol on Baam's clothing as the mark of the 'slayer' of FUG, much to everyone's distress. Wangnan wonders why a Regular on the 20th Floor is part of FUG. As the 10th person arrives, Wangnan warns him to be careful to no avail. After the Baam defeats everyone else, he turns his attention to Wangnan, who begins running away like a coward throwing "Super Strong Shinsoo Bombs". As none of the Bombs have any effect, and Baam pulls him to the ground. He uses a last resort cheap bomb hoping to get away. He realizes that it had an effect and throws another one. After the smoke dissipates, a giant lobster-like mass appears around Baam, who then stands up recovered. At that point the test ends.

Wangnan and the survivors proceed to a large room, where they share a little food. A massive Regular enters, on the verge of death, and Wangnan tells the others not to help him, as he would probably fight them if they did. Other teams begin to enter, and Wangnan recognizes the girl who set him on fire among them. Also to his shock, he finds the Kim Lurker is also in the test with the Lurker boss's son. Kim tells him about the Regulars who have come to participate in the test, including the mercenary "Devil of the Right Hand" who managed to beat Hatsu.

The Administrator for the next test, Love, introduces the next test which is a Shinsoo Strengthening Test in which the top 8 get to pass to do the final test. Unfortunately, Ja Wangnan was only able to get 10th in the test and mopes in the corner. After everyone has taken the test with Viole placing first, Ja Wangnan is placed 15th. Thinking that his dreams and life is forfeit, he begins to cry. GoSeng scolds him for not acting more manly, but gives up when he ignores her. When Love announces that Viole will be picking the remaining 7 team members, Wangnan jumps up and introduces himself to "Viole-nim." He advertises himself in a comedic fashion as "a man beyond his stats" and that he could sing and dance. After seeing how this has no affect on Viole, he drops to his knees and begs. This causes the other regulars to either look at him with pity or contempt. Arkraptor takes this chance to jump in with his own plea, followed by Horyand and MiSeng. Yeon also walks onto the stage, assuming she already had a spot on the team. Wangnan points out some of their bad points in order to make himself look better. Viole makes the bold statement that he would not pick any of them, since they were unqualified, and states that he is their enemy. This surprises everyone.

Powers and Abilities
Ja Wangnan is a fairly weak man, and is at a relatively normal standard for Regulars. He doesn't do particularly well in his tests, as he is bankrupt and in debt, and commonly runs away from the loansharks, if possible.

He places his trust in powerful Shinsoo Bombs, which he is quite accurate with. He will also use normal explosives as a last resort.

If his claim to be a "prince of Zahard" has any truth to it, he could have some powerful dormant ability, but if so, he has yet to show any signs of it.

Appearance
He usually wears jump-suit like clothing, with a slightly more intricate coat, but wears a formal suit underneath. He has red horns at the top of his neck, and wears a ring bearing the emblem of Zahard.

Personality
He is quite a haughty person, as shown by his confidence that he will one day conquer The Tower and rule over everyone. He has an unbreakable determination, no matter how many times he is beaten. He seems to be easily influenced by young girls such as Miseng. Possibly due to his repeated failures, he has a practical mindset for completing the tests such as when he says that it's better to drop the person who looks the strongest in a test during the voting.

Family Legacy
Wangnan has almost no family, and has no one to rely on. He is stated to be the Prince; the prince of what, unknown.

History
Ja Wangnan is a enigmatic man, he bears the crest of Zahard, but yet seems like the bottom class of Regulars. He may indeed be the crown prince of Zahard, but he shows no knowledge of this possibility. Not to mention that the ring could also be just a fanboy souvenir, self made, stolen, or even found by accident.

Trivia

 * It's seems pretty obvious, but the Shinsoo Bombs look like Pokéballs from the Pokémon series, Dive Balls in particular.
 * He's horrible at strength tests. He's 15th in the Shinsoo Strengthening Competition. Also interesting to note, he's worse than Nia when it comes to shinsoo strength.
