Twenty-Fifth Baam/Appearance and Personality

Appearance
In Part I, Baam is a young boy with dark brown hair (often called black) and amber/gold eyes. He wears a brown long sleeved shirt, a red vest and beige pants. After the Crown Game test he received a lowest tier Regular uniform and a headband from Koon. He is described as good-looking and cute by the Black March, Ha Yuri Zahard, and Androssi Zahard. Yuri also calls him a "hotty" in Part II as a semi-joke.

In Part II, Viole (Baam's alias) is taller and he has grown out his hair, with the bangs covering part of his face, more specifically his eyes. One of his new outfits consists of a black robe, beige pants and clothes with the mark of FUG. Another new suit, however, is a more formal dress, wearing a purple and black-striped shirt and black pants. He is described to be handsome by Yeon Yihwa.

Personality
In Part I, he is a caring young boy who has high empathy, and understands the true meaning of life, due to his life before The Tower being spent in almost complete solitude. He hates loneliness and other people's loneliness, seen when he urges Androssi not to be lonely and even more so when he comments on Rachel's story. He's very naive and unknowledgeable about the Tower. During Part I, he only climbs the Tower to be with Rachel.

In Part II, Viole is far more violent, and now completely understands that to climb The Tower, he must be pre-emptive and prepared to both engage in combat, and eradicate all opposition. He's become more introverted, rarely ever speaking, or displaying any signs of emotion. He's also quite cold and calculating, interacting with others only out of necessity, and will take advantage of a situation to defeat his opponents.

It's possible that Viole became cold and distant in order to protect himself from getting hurt again, and distances himself from others, opting to take tests as a solo even thought the tests are intended for groups. This is to avoid involving others in his dangerous quest.

He joined FUG at some point after leaving the Second Floor, sharing the same goal as FUG: to slay Zahard and his allies. Later however, it is revealed he was infact blackmailed into being part of FUG. Frankly, he was forced to become a Slayer by Yu Han Sung, as he had threatened to kill his friends if he refused or acted weak.

As of Chapter 91, he still likely retains high empathy for others but has closed himself off. However, that doesn't mean his heart has changed. As an empath, he is likely connected to others' emotional states and can feel and relate to their joy, sadness, hatred, suffering, etc; in a way, he likely feels very guilty or even depressed for eliminating the test takers because he can feel their emotions from failing the test and is the very cause of them. It would not be wrong to assume he's punishing himself or feels deserving of punishment because of the tremendous guilt he feels, yet at the same time, he also seems to recognize in the current testing system, "there is no way that everyone can be happy. It's only possible someone will be happy." In other words, he probably feels extremely miserable over the decisions he is making, even though he doesn't need to be responsible for everyone. It should be noted that he still retains his childish side, despite his cold demeanor, as shown by his amazement at the sea.
