Kallavan/History

History
3000 years ago, after recently becoming a Ranker, he fought Ha Jinsung and was still able to stand up after taking a beating from him. Ha Jinsung asked why a great talent like Kallavan was staying in an isolated area. Kallavan mentions that he belonged to a village that guards the 'Essence of Bravery' and that he is its current guardian. Whenever a person from the family becomes a Ranker, they fight the person that is currently guarding the gem, with the stronger ranker killing the weaker ranker and, if applicable, replacing them as the guardian of the gem.

Ha Jinsung tells Kallavan that his bloodline already produced the ultimate achievement which is Kallavan himself and that he should be the one to inherit the 'Essence of Bravery'. On the same day, Kallavan decides to smash the bronze statue holding the gem and claim the essence for himself. The next time Ha Jinsung saw him, he was already as strong as a High-Ranker. Ha Jinsung suggests Kallavan become a Slayer of FUG, but he kindly refused and that ends their relationship. Kallavan then went on a journey, became a High-Ranker, and started to make a name for himself as he defeated and collected many great warriors, making them his servants. At one point, Kallavan met Zahard and determined that Zahard is the one person that can make his dream come true. This led to him and his followers joining Zahard's Army.

Tower of God: Part 2 - The Hell Train
Kallavan and his troops are seen travelling to the Last Station in their warships.

Evankhell
He and his troops were stopped by Ha Jinsung and were told to come out and fight.

Kallavan
Kallavan was in his warship when Ha Jinsung appeared and said he will destroy his warship using one of the shinsu cannons from El Robina, an Anti-High Ranker weapon originally belonging to Zahard if he doesn't come out. Kallavan tells the third division commander to move all the troops back and said he will personally beat Jinsung. Ha Jinsung calls Kallavan out on his arrogance and in reply, Kallavan said he is in a position to be more arrogant. He is forced to fight his former teacher, saying he won't lose with his power. During the battle with Ha Jinsung, Kallavan said this war isn't about capturing a couple of regulars, but to stop a greater rift in the tower and the mission will go down in history as a great epic. During the fight, Ha Jinsung was being pushed back, and his hands were shaking from the impact of Kallavan's attacks. As the battle wore on, Jinsung began to fight using his greater techniques and was able to land multiple successful hits on Kallavan. They stopped fighting for a moment, and Kallavan tells Ha Jinsung about the he saw in the Essence of Bravery. He mentions to Ha Jinsung, that the man in the gem was someone from the ancient times, and the power in the gem belonged to him. Kallavan says the real reason he refused the offer to become a slayer was that he fears that his fate might end up like the man in the Essence of Bravery. Kallavan said he later decided to use his power to serve Zahard, and unite everyone under him, so wars and tragedies will vanish and the tower would be at peace. Kallavan then proceeds to unleash his power and uses his transcendent skill, Atomic Explosion, which leaves Ha Jinsung bloodied and seemingly critically wounded. Ha Jinsung was left with no choice but to use his (presumably) strongest attack, Dragon Tiger Gate, which was powerful enough to almost stop Kallavan, save for the fact that Jinsung was unable to follow up with another attack because he was too exhausted to do so. Kallavan then crushes Ha Jinsung's arms rendering them useless. Ha Jinsung screams in agony and was also stabbed in the back by Khun Maschenny Zahard who later arrived without Ha Jinsung noticing.

After beating Ha Jinsung, Kallavan immediately rushes to the teleporter to get to the Last Station and appears right in front of Baam on the great battlefield. He sees the battle getting out of control because of the battle between Khun Royale Elliot and Evankhell. The moment when Kallavan tries to attack Baam, Androssi Zahard saves Baam using Bong Bong, but Kallavan easily pulls Androssi away and restrains her, which leaves Baam alone. Kallavan tells Baam that his master is probably dead because of him. This caused Baam to break down and attack Kallavan with all he had, but in the end, he didn't hurt Kallavan in any way. Baam proceeds to ignite one of his thorns to use a technique that was used to beat Data Zahard. After the attack, Kallavan was disappointed that Baam didn't even scratch him with the attack. Karaka appears in front of Kallavan and asks if his master is dead, and Kallavan said he isn't sure. Karaka told Baam to run because he believes his master isn't dead due to Kallavan being unsure of his death. Kallavan rushes to attack Baam before he could get away, but Evankhell stops him, and Kallavan asks why she is helping the regulars. Evankhell said she wasn't interested in Baam until she saw that he had managed to inflict a small wound Kallavan. He was surprised Baam made even a small scratch because he hadn't felt it. Kallavan then regrets having stalled in order to understand the boy whom he was supposed to kill. He then goes all out to kill Baam even with Evankhell, Yuri and Karaka in the way. He rushes towards Baam at high speed while tanking all the attacks from the High-Rankers, even Evankhell's Death Sentence attack couldn't stop him. He uses Atomic Explosion to break free of all the attacks, which also destroyed many warships around him. The moment when he was about to get to Baam, Yu Han Sung, Ship Leesoo came to the rescue, and they all teleport away.

New Wave
Kallavan screams in anger and blames himself for the mission's failure to kill the regulars. Elpathion arrives by Kallavan's side and asks if he intends to go after the boy still, despite the army being tired and injured. Elpathion says the army needs to rest, but Kallavan says he'll kill the boy himself. At the end of Part II, the 4th Army and Kallavan were seen to head straight into pursuit after Baam and his friends managed to escape from the Army by warping the Last Station. One of Kallavan's servant then reported that they failed to track down the location of the last station due to its mysterious disappearance. The Last Station disappeared because of Madoraco's Ghost Ship's invisible cloaking special ability.

Deng Deng
After the battle at the Last Station, Kallavan lost his position as Corps Commander and was said to be guarding the secret prison where Ha Jinsung is being kept.

The Wall of Peaceful Coexistence
Somewhere in the Tower, Kallavan approaches the Wall of Peaceful Coexistence and with one arm tied behind his back, he walks towards the wall to proceed with its destruction.

The Wall with a Sleeping Forget-Me-Not
When Khane was captured by the civilians to be executed, she couldn't hold her anger and resentment any longer and finally contacted the pocket that Kallavan gave to her. She asked Kallavan to help her reach the sealed tower. Kallavan who has been waiting for this moment was very happy and proceed to reach the rendezvous point which Khane selected. Along his way, Kallavan killed several guards of the wall, which all of three of them was identified as Rankers (marks on their both shoulders) that were dispatched to capture him. By the time he finished to kill the last standing ranker, Khane arrived behind him. The two of them then proceed to go to the sealed hero tower, in order to unseal Dowon. Along the way, they encountered many guard rankers, but Kallavan can easily take care of them. As they arrived in front of the sealed hero tower, the most powerful guardian and also the last line of defence, ranker Tonki has already been waiting to prevent Kallavan and Khane entering the sealed hero tower. Kallavan easily beats Tonki and moves on. Upon entering the hero's tower, behind Kallavan was White and Hatsu.

Kallavan vs White
White reveals to Khane that Kallavan was an Army Corps Commander. Then Kallavan admits the truth and said he's going to persuade Dowon to join their side or kill her. Kallavan then fights with White and easily overwhelms White. Kallavan gets a cut from White's new sword call 'Spinel'. Kallavan then gets even more cuts from White's Spinel but he recovered all injuries by using the Essence of Bravery. Kallavan dashes in while neutralising all of White's attack, then he gave White a good punch. Soo-oh then appears to save White. The town's hero get unsealed moments later and Dowon wakes up.

Dowon
Kallavan flies up to greet Dowon. Kallavan also sees Baam next to him and when Baam asks about Ha Jinsung's whereabouts, he couldn't answer because that information was off-limits to a low ranking soldier. Kallavan tries to attack Baam but was saved by the Elder's Guide. Kallavan chases Baam and his group but was stopped by Dowon and requests Kallavan to leave them alone in exchange for her joining his side. Kallavan, as a man who strictly follow's his mission decided to focus on the main mission to obtain Dowon to join their side and leaves Baam alone. After completing the mission, Kallavan contacts HQ. They want Kallavan to assemble at The Nest for the next mission.

The Nest
Two days after the battle at the walls, Kallavan and Dowon are seen inside his warship conversing. Kallavan greets Ha Cheonhee and then goes inside to meet the new Army Corps Commander, Po Bidau Lyborick Khun. The new commander promotes Kallavan to Company Commander for completing his mission successfully.

A Rough War
Kallavan sees Baam again at the second defensive wall and tells him to back off or else he will attack Baam, threatening to reduce Baam to dust in 5 seconds. Karaka appears behind Kallavan and tried to attack him but Kallavan, without looking, easily stopped Karaka's attack. Kallavan apologises to Ha Jinsung in advance for what he's about to do to his two students. Karaka and Baam attack Kallavan together however, none of their attacks were effective. Kallavan finally reacted after being attack by Baam's shinsu black hole sphere.

VS Kallavan
Kallavan is then challenged by Baam using the Thorn and 3 Orbs, being impressed by his growth, and with help from Kallavan, Baam's last attack manages to break through the Essence of Bravery and cut him, further impressing him, who notes that Karaka may be tough but he isn't deadly while Baam is weak but lethal to him. Kallavan then attacks Karaka to lure Baam over and succeeds, proceeding to easily overpower Baam's attempt to attack him with his Partial Transformation and badly injure him, ridiculing him for risking so many lives to save one person and stating FUG's belief of his potential to be the greatest king after Zahard was wrong and him taking power would only cause chaos to the world. Kallavan gets restrained by Karaka for a brief moment and tells Baam that he is just an ordinary person and is not unique like Zahard, who treats everyone except for the 10 Family Heads, equal and as such doesn't care if he loses a few of his subjects and remains solemn and tranquil in any situation. Kallavan gets attack by Baam's new attack called 'Twin Wings' which heavily damages his arm, causing Kallavan to acknowledge that it was only a bit too weak to fully cut off his arm and he underestimated him but no longer, stating that Baam's potential will allow him to threaten Zahard in the future. Kallavan then attacks Baam while Baam is exhausted but was saved by Karaka and Dowon. After personally experiencing how strong Baam is currently, Kallavan can no longer spare him and attacks to kill him, eventually breaking Baam's newfound Blue Shield.

However, before he could kill Baam, White, now at full power, appears and stops his attack, with Kallavan commenting on how much stronger White is than the last time they fought. After White easily defeated Yolker and challenged Kallavan to remove his seal, which he refused to do, the two fight with White now more than capable of matching him without using any special sword skills, the slashes acknowledged by Kallavan himself as being heavy and swift, and eventually Kallavan gets pushed back as he still refuses to undo his seal. Then Lyborick contacts Kallavan, revealing that he plans to blow up the 4th Army Corps flagship to destroy the Cage, knowing they were up to something with the Cage as it was moving so slowly, and orders Kallavan to do what he can to ensure the plan's success and calm down the Corps, stating that the new recruits for the 4th Army Corp will ensure the future, giving Kallavan permission to release his arm. Kallavan reluctantly agrees but promises to kill Lyborick if the plan fails, which simply causes Lyborick to agree that if the plan fails, Kallavan can come kill him and take his position but until then to follow his orders as Kallavan gives in and releases his arm. While ordering his followers to not stop the flagship, he and White then continue fighting, Kallavan now equally matching White's Cullinan and withstanding it's attacks until White uses his Sapphire Single Shot Deadly Sword of Light that causes too much pressure on his wounded right arm, forcing him to blow it up. However, Kallavan simply creates another arm with the power of the Essence of Bravery to continue fighting.

Before their fight can continue, Kallavan's attention returned to Baam as he activated a mysterious power that causes him to be surrounded in a white aura, but he is forced to continue fighting White and his attempts to attack Baam was repelled by Cha, causing Kallavan to wait for the right opportunity to kill Baam. He orders his followers to stop Baam but they are easily repelled by Cha and Kallavan himself starts to become desperate to make sure his followers don't die in vain, forcing White to combine two powerful technique to stop his attacks. However, before he can continue attacking, Kallavan watches in shock as the flagship finally explodes, taking out many of his followers, and fond memories with his followers causes Kallavan to abandon the fight, feeling the grief of watching as his loyal subordinates die. When Baam saves his enemies anyway, Kallavan remains silent when challenged by White to continue fighting, mourning the loss of his followers. When Cheonhee asks him if it's true that Lyborick abandoned them, Kallavan confirms it and asks if she will follow him to break military law by killing Lyborick and taking back his position.

Tower of God: Part 3 - The Second Defensive Wall
Kallavan decides to temporarily allign with Baam to kill Lyborick, promising in return that he will not attack until they rescue Jinsung and accepting leading the charge to the next wall and destroy the new 4th Army Corp. He crosses the Wall moments after Baam, asking for Lyborick and stating he does not want to destroy the 5th Army Corp as well but will if they get in the way. Yasratcha then appears, stating that Kallavan is far too strong for his forces to stop them from provoking him.
