Khun Aguero Agnis

"Whatever it takes... I will take you and Rachel to the top." - Koon to Baam

Koon Agero Agnis is a son of Koon Eduan, the current head of the Koon family, though he is referred to as Mr. Koon. He was expelled from the family because his older sister failed to become one of Zahard's Princesses. He teamed up with Baam and Rak and passed multiple tests with them. He was assigned the Light Bearer position and was awarded Best Seed. He is highly intellectual Regular, who has performed well on all of the tests so far. He is currently helping Rachel reach the Top.

Appearance & Personality
Agero has white hair and navy blue eyes. He wears a bandana tucked inside his hair, in some occasions he has removed it and tied his hair with it, the significance of the bandana is not known. He wears a white shirt and black tie, and carries a briefcase. This may change in Part II, however.

He is depicted in the series as a cool-headed and highly intellectual character, often the schemer of the group. He is also rather smug when his plans work. He was able to amaze even the Rankers with his planning during the Hide-and-Seek game, and has been described as "a dangerous being". He is skilled in his manipulation of others, and has the mindset of "a ruler". He doesn't seem to be the type of person to follow the rules of others. He is rather friendly most of the time, but can be extremely ruthless. He can also be rather playful while toying with others and it is subjective whether this trait is due to his age or his personality.

History
Not much of Koon's history is known, other than that he is a member of the Koon family and that he was expelled due to the failure of one of his older sisters to become a Zahard's Princess.

It is hinted that he cared deeply about Maria who he helped to occupy a position once held by his older biological sister. He helped Maria because she cared for people and because he thought that she deserved to be happy.

Relationships
Baam: When Koon met Baam, he tried to become friends with him because he thought he might be useful. Since then he seems to have bonded with Baam greatly, and he found something in Baam which Koon thought he had lost. He therefore holds great respect for Baam and has a great freindship with him, to the point that he would put the reputation he holds so dearly on the line just to help Baam. It has been shown that Koon respected him so much that he wanted to reach the top with him, and even carried on his wishes after he thought Baam had died.

Rak: Koon is often annoyed by Rak, although he seems to have come to appreciate him a bit. However, he often makes snide comments about him.

Hatsu: Relations between Koon and Hatsu were frosty at best, but Baam helped them get to know each other.

Rachel: Koon met with Rachel after the Crown Game and has promised to not reveal her identity to Baam.

Ship Leesoo: They seem to get along with each other. Leesoo seems to be able to read Koon better than most.

Powers and Abilities
Speed and Agility: Koon is a trained fighter, and has demonstrated excellent physical skills. He can run at incredible speeds, and it is indicated from the light around his feet that he uses Shinsoo to do this.



Briefcase: Koon's briefcase Manbarondenna has an insane number of functions, including: Lighthouse Control: Koon is good at moving and using lighthouses. As of Part I, he is known to be able to wield 2 lighthouses.
 * Toughness: It can resist knife blows, bullets, and more, nothing has yet been seen to damage it. Koon uses it as both a shield and a weapon.
 * Pocket Dimension: The briefcase can hold large amounts of objects inside it easily. It can even suck up enemies.
 * Cloning: The bag can make copies of any non-alive object placed inside. There are still material that cannot be copied. (Most material in 2nd Floor cannot be copied.)
 * Elasticity: The handle can stretch huge lengths.

Perception and formulating strategies: Koon is a natural genius. He is smarter than Rankers, and fools them quite easily. He is the mastermind of all sorts of tricks. He can often see through other people's strategies and make the best plan to exploit the enemies' weakness. In the Hide-and-seek test for team A, Koon delibrately used Quant's irritable nature and hasty judgement against Quant. Even more brilliantly, Koon secretly helped Quant to defeat his own team in order to ensure the maximum number of Koon's "real friends" pass the test.

Tower of God: Part 1
Koon began on the second floor with the other Regulars. He found a few allies during the first test and stored them in his briefcase. He ran into a large red regular, and asked him if he wanted to become an ally. The regular remarked that trying to find allies was stupid as the test was all about killing each other, to which Koon replied that finding allies was important, and was part of the "mindset of a ruler". He stated that the regular was not even fit to be ruled, and promptly defeated him. He then encountered Baam, and after talked to him for a while before decided he was useless, prepared to move on, when they were attacked by Rak. He and Baam hid behind a rock from Rak while trying to decide what to do about their situation. Koon noticed that Baam had the Black March, and decided that if Baam possessed such a weapon he was probably special and could make a useful ally. He introduced himself to Baam while Rak continued to rage at them on the other side of the rock. It was then announced that they had to find a teammate, and he and Baam were left with no option other than to grab Rak, which upon failing to secure his cooperation they did. Paired with Rak and Baam, Koon managed to get through the barrier test easily. He had difficulty figuring out Yu Han Sung's door test, as he was focused to hard on the "clues", but was saved when Rak simply kicked open a door. He played the Crown Game with his team, and he and Rak easily demolished most of the other teams using their fighting skills. He took a break in the middle and let the allies he had been storing in the suitcase loose to fight for them. The later opponents were more skilled, but they still looked like they were going to win. However, when Baam jumped off the throne to protect Rachel they lost.

Koon was then assigned the Light Bearer position and seeded first. He did well in the classes (although he commented that they were boring), and with Baam's help managed to collect a list of "friends". He was then placed on Team A for the Hide and Seek game. He masterminded the whole team expertly in an attempt to capture Quant, but the attempt failed making Quant feel overconfident just as Koon wanted. He then moved to the second part of his plan to help his team's It escape. He confronted Quant, and tried to make him think that Anak was in his briefcase, while really she was riding one of his lighthouses. Quant figured this out and tried to foil the plan by pushing Koon off a cliff, but it was then revealed that Koon had planned for that as well and had set up a pulley system attached to the lighthouse Anak was on. Anak was carried up to the exit while Koon was saved. However afterwards Laure, under Koon's command, blasted Quant up to Anak, and he was able to catch her.

Afterwards Hide and Seek game, Koon appeared to lament his failure with his team, but it was then revealed that he was actually planning to get his list of "friends" through the test, and that he had made a deal to help Quant catch Anak, in order to facilitate things for his "friends" on the other team.

Afterwards, he submitted evidence to Leo-Ro proving that a Ranker had intevened in the previous test, so that Rachel could proceed despite being injured.

During the Submerged Fish Test, he masterminded the team to destroy most of the threats. However, he was unable to stop Baam from "dying", and as a result of this felt guilty and decided to assist Rachel on her quest for the stars..

Tower of God: Part 2 - The Return of the Prince
He is yet to make an appearance in Part II, but his sister, Koon Maschenny Zahard, has made her debut.
