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 prince by title, but based on Repellista's reaction to him climbing he may indeed have dormant power). 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. Quickly followed by him failing because a woman dubbed 'Molotov Woman' defeated him, by burning him with fire, likely created with Shinsoo. He then nurses his burns and claims revenge, immediately after the loan shark, Kim Lurker comes to claim his money. Ja 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 that had failed the 20th Floor test at some point, comes to deliver his food, which the loan shark pays for claiming Ja Wangnan will pay for it with his body later. Ja questions the Regular about why she's delivering food, however he answers his own question in a slightly condescending fashion. 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. Ja is very pleased by her by so touched by just a few sentences, 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' the mysterious figure to team up with him, that seems to have worked. He tries to make small talk but the long-haired person stays quiet. 3 minutes later, another competitor comes in and Ja Wangnan rallys the long-haired person to fight with him. He's intimidated by the next competitor's 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 Ja 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 Ja 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, Ja Wangnan denounces everyone saying that it's a test and everyone should be fighting each other, much to the distress of the others. A grey-haired person who comes in catches the attention of the large person and Ja Wangnan. The grey-haired person tells Ja 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. Ja Wangnan chooses the 'silver shithead' (it's unknown if he did this to protect Miseng or not) saying that the strongest one should be voted off first. Before the large person chooses, the long-haired person says there's no need for voting because he can make everyone fall by his hand.

The mysterious long-haired person begins fighting the grey-haired person and the giant at the same time. During the fight, Ja Wangnan hopes that all three of them will kill each other at the same time until the long-haired person reveals that he's a Wave Controller. Goseng finally recognizes the symbol on his clothing as the mark of the 'slayer' of FUG. Ja Wangnan wonders why a Regular on the 20th Floor is part of FUG. As the 10th person arrives, Ja Wangnan warns him to be careful but the long-haired person quickly dispatches him as he enters. After the long-haired person knocks out the grey-haired person and the giant, he turns his attention to Ja Wangnan, who begins running away like a coward throwing "Super Strong Shinsoo Bombs". As none of the Bombs have any effect, the long-haired person pulls him to the ground. He uses a last resort cheap bomb hoping to get away. He realizes that it had an effect on the long-haired person and throws another one. After the smoke dissipates, a giant lobster-like mass appears around the long-haired person.

Powers and Abilities
Ja Mangnan 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 bank.

He places his trust in powerful Shinsoo Bombs, which he is quite accurate with.

He most likely has an incredibly powerful dormant power.

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 the delivery girl and 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.
