Kallavan/Abilities and Powers

Powers and Abilities
Even in his youth, Kallavan was already powerful enough to take a beating from Ha Jinsung, a top 100 High Ranker. Jinsung then praised Kallavan's great talent and noting he possessed serious power for someone who had not been a Ranker for a long time. After taking Jinsung's suggestion, Kallavan obtained the Essence of Bravery, which was guarded by his family bloodlines for generations. And the next time Jinsung came to visit Kallavan, it has made him dramatically more powerful to the point that Jinsung was impressed enough he noted Kallavan could have easily become a High Ranker even before he began his centuries of training and offered him to become a Slayer, but Kallavan refused it respectfully.

After easily becoming a High Ranker and the leader of the 4th Army Corps of Zahard's Army Kallavan was among the most dominant High Rankers in the tower, having defeated and recruited many great Rankers and earning his sobriquet, "The Human Hunter. Jinsung, a top 100 High Ranker, was worried about having to fight him, saying that it would not be easy. Kallavan proved himself a match for Jinsung and was able to pummel him into a bloodied state and destroy his arms. After receiving severe injures from his battle with Jinsung, Kallavan remained able to easily block the attacks of Baam, who was wielding the power of Black March and the Thorn. He also could fend off Ha Yuri Zahard wielding the Green April. Though he admitted openly he cannot fight Evankhell, Yuri, and Karaka all at once in his injured state, he was able to ignore and tank their attacks for long enough he was nearly able to get to Baam and hit him with his Atomic Explosion. His mere arrival was enough to inspire the pressured members of Zahard's army.

Kallavan's might was enough that despite his failure during the Battle of the Nest, Adori Zahard still considered him worthy to keep in the Army, saving him from execution or expulsion and allowing him to remain as a normal soldier. Khel Hellam even described Kallavan as a "warrior as mighty as an entire (Zahard Army) Army Corps." Even with one hand sealed behind his back, Kallavan is still extremely powerful. He was able to effortlessly kill Tonki, who is a High-Ranker level fighter, with one punch. Khane, who watched this, feared that he might be too strong even for Dowon to defeat. He was also able to tank all of White's attacks with his bare body and even broke his sword, forcing White to make a new, stronger sword. Once Kallavan used a shinsu boost and unleashed the Essence of Bravery, he quickly overwhelmed White who was using the strongest sword he could create at the time, Spinel. Dowon also acknowledged Kallavan had enough power to defeat all of Baam's allies and even surrendered to him so he would let them go. During his fight with Baam against Kallavan, as the former Army Corps Commander easily repelled all their assaults, Karaka expressed disbelief that he could possess incredible attack power while his defensive capabilities are also off the charts. He was also able to hold off the now at full-power White with one arm tied behind his back and once he was finally allowed to break the seal on his left arm, Kallavan was able to fight White using Cullinan to a stalemate, with White even admitting to being surprised by Kallavan's power. Lo Po Bia Yasratcha believed he would be capable of easily annahilating the Fifth Army Corp without him present and upon Kallavan agreeing to participate in Gakja Dosaeng, expressed relief over not having to fight Kallavan. SIU described Kallavan as being capable of having the advantage over Yasratcha in a one-on-one combat. Upon arriving at the finishing line of his Map, Kallavan stated that the challenges of the game were too easy for him.

Physical
Master Hand-to-Hand Combatant: Kallavan is an extremely skilled martial artist, able to compete against Ha Jinsung, one of the most skilled Ha Family members in hand to hand combat. He was able to push Jinsung back multiple times throughout their battle. Even with one hand tied behind his back, Kallavan was able to easily overpower the guardians of Dowon's tower with brute punches and could block the blows of Tonki without much effort before defeating him with a single punch. He was also able to push back White's sword, and then grab it mid-swing during their fight.

Immense Strength: As such a powerful martial artist and High Ranker, Kallavan holds enormous amounts of physical strength. He was able to effortlessly backhand a man through a rocky wall with enough force to crack it with a single hand, down guards of the Wall of Peaceful Coexistence with a single brute blow and his fists were strong enough to damage White's sword just by colliding into it. Once using a shinsu boost, he was able to punch White with enough force to visibly hurt him. Kallavan was even able to completely destroy Karaka's Armor Inventory Armor Storm with just a single punch and was likewise able to tear through Baam's Thorn empowered Red Thyrassa Partial Transformation blade and badly injure him.

Immense Speed and Reflexes: In addition to his tremendous strength and durability, Kallavan also possessed tremendous speed and reflexes, being able to swiftly cover the distance between him and Jinsung twice and trade blows with him at vast speeds before being outpaced while not using the Essence of Bravery and able to pressure Jinsung and land hits on him upon using the Essence of Bravery. He even could casually react to Yuri's attack with the Green April despite not having his attention focused on her. When fighting White the first time, Kallavan was able to easily surpass the weakened Slayer's speed to overwhelm him with only one hand, perfectly countering his attacks and pressuring him with his own assault, and upon using a shinsu boost, Kallavan was able to easily overcome White's Spinel that had previously pressured him to comfortably push him back while blocking all of his attacks, even going as far as to casually catch his blade mid-swing before swiftly delivering attacks on White before he could react. He also easily reacted to White's attack from his blind spot while focused on Baam. When fighting Karaka and Baam, Kallavan was able to effectively block and counter all of their shinsu attacks with his own defenses and also stop Baam before he could use Shinwonryu on him, to where Baam admitted he was too fast for him to be able to hit without using the Thorn. Even with Baam using the Thorn and Karaka backing him up, Kallavan was still able to successfully block all of their attacks to where he commented Baam's last attack pierced his defenses instead of being able to breach Kallavan's responses. He was also able to easily blitz Karaka to deliver devastating hits on him and react to and overpower Baam's incoming assault from behind with his own. He even managed to keep up with the full-power White's swordplay, which Kallavan himself described as being both swift and heavy with only one slash hitting him while his hand was still tied and once using both hands and his full power, Kallavan was able to evenly match White, successfully neutralizing all of his attacks.

Immense Durability and Shinsu Resistance: Kallavan's body is extremely tough, even tougher than those of the Ha Family.He was able to take an elbow to the head from Jinsung without flinching, and Jinsung was surprised by how tough he was. He took no significant damage from Jinsung's Demonic Storm and Iron Defense, only feeling slight pain. He was able to survive Jinsung's ultimate technique, Dragon Tiger Gate, albeit with a serious injury, to the surprise of Jinsung who had thought he killed Kallavan with that attack. After that, Kallavan's durability was still enough to be able to successfully teleport to the battlefield while the warp device was exploding. He was able to easily take Baam's Black March augmented attacks without even being moved by the blows. He could also deflect blows from Yuri's Green April with his bare hands without suffering damage. Even Baam's strongest attack Remnants of Stars - Stardust was only able to inflict minor injury when he fully activated the Thorn. Afterwards, Kallavan was still able to charge directly at Evankhell, Yuri and Karaka, pushing past their combined attacks in order to get through to Baam with little strain and only expressing pain when hit by Evankhell's Rare Orb - Death Sentence. Several years later, Kallavan once again demonstrated his superior durability. He was able to effortlessly fight against White's sword with his bare hands without suffering any damage, with White noting that his fist seems to be diamond hardened for countless years. This forced White to create the "quickest and sharpest" sword he could make called the Spinel which managed to finally cut Kallavan. However, it is revealed that the former Army Corps Commander wasn't even using a shinsu boost, and once he did, White's sharpest sword was no longer effective. Even when White used one of his Lethal Moves, Kallavan simply grabbed the sword with his bare hand. Kallavan was later able to take Karaka's White Day even when it was performed at Level Two and was directly hit twice with no damage to himself. Kallavan even mocked the attack, stating it was not as strong as Jinsung's. Baam subsequently joined the attack on Kallavan and used his Airwave Zero from behind but yet again the Human Hunter didn't even flinch. After this Karaka suggested there was no choice but for him and Baam to consistently pound Kallavan with multiple attacks. Even after all this, Kallavan did not react until Baam decided to use Shinwonryu, blasting him away before he could get hit by the attack. Baam speculated that the Shinwonryu is capable of hurting the former Army Corps Commander. He was also able to take Baam's Twin Wings - Black and White to his right arm when he was restrained by Karaka and unable to defend himself head-on, noting that the attack was just a little too weak to completely cut off his arm, and when fighting the now full-power White, he was able to withstand his Cullinan, with White noting that up until he used his Sapphire Single Shot Deadly Sword of Light, his attacks could not damage Kallavan to the same level as Baam's attack did

Essence of Bravery
After obtaining the gem inside the bronze statue his family had been guarding for decades, Kallavan obtained the power of the Essence of Bravery, which granted him a tremendous boost in power and made the shinsu in his body flow peacefully and dramatically sharpened his mind and body to where even Ha Jinsung felt chills. He has displayed numerous powerful capabilities with the Essence of Bravery.
 * Shinsu Control: Kallavan has displayed an incredible amount of skill and power with shinsu, which takes the form of a deep bluish hue when controlled by him due to the Essence of Bravery's power.
 * Shinsu Bursts and Blasts: Kallavan's preferred method for long-range combat is to release extremely powerful blasts of shinsu from his hand, which he can also use defensively by manifesting bursts of shinsu around him. Without using any special technique, his shinsu proved strong enough to destroy Yuri's Rose Shower and easily repel attacks from Karaka and Baam, overcoming Karaka's defenses with a single burst, as well as equally match the attacks of the fully-powered White's sword attacks for a while with only one arm, being able to match his Cullinan upon untying his arm and even forcing White to combine his Deadly Spirit - White Magnolia and Diverging Deathly Swords of Heavenly Spirit to stop his onslaught.
 * Lethal Move: Hurricane Shaker - Backlash Bomber: Kallavan starts this attack by punching his opponent which sends them flying backwards. He then follows this by clenching his fist to create a large shinsu blast behind the enemy as they are recovering from the first punch. This technique was strong enough to push someone like Jinsung backwards. It was also capable of easily blasting through Androssi's shield and sending them flying a great distance. Kallavan was later able to use this technique to damage White enough to make him cough blood.
 * Lethal Move: Hurricane Shaker - Backlash Big Bomber: A stronger version of the Backlash Bomber that is powerful enough to damage Jinsung to the point of spitting blood.
 * Kallavan Essence of Bravery Transcendent Skill - Atomic Explosion: An extremely powerful technique that Kallavan used against Jinsung, and also against Baam at the Last Station. Kallavan punches forward and unleashes an extremely large amount of shinsu, resulting in a massive explosion. The technique's power is such that it left Jinsung in a bloodied state with one of his arm's completely mangled and almost reached Baam through Evankhell's flames.
 * Body Reinforcement: Kallavan is also capable of enhancing himself with incredible amounts of shinsu using the Essence of Bravery, dramatically increasing his physical capabilities, to where while previously Ha Jinsung was able to competently handle him in close-range, with the Essence of Bravery activated, Kallavan nearly completely pushed him to the defensive. He can also control the amount of power used in the reinforcement, limiting it to simply enhancing his hands, which still possesses devastating force, able to crush the High Ranker-level Tonki's fireball within moments and even kill him with a single punch, along with casually overwhelming and severely damaging Karaka and Baam with physical force repeatedly.
 * Regeneration: Kallavan was able to instantly heal all the cuts White made with Spinel upon activating the Essence of Bravery.
 * Hand Creation: Kallavan was even capable of creating a new arm made out of shinsu.
