Muzaka has a tall, muscular, fair-skinned body that is covered with large battle scars. Muzaka has long gray hair, with grayish eyes. Under the effects of the Union's control, his eyes appeared to be completely white, showing no irises or pupils. During the time he was sleeping and after his awakening, his attire consists of only black briefs. However, in the past he wore light brown pants and a red blazer with white fur lining.
In the past, he seemed quite lively and approachable, but slightly arrogant; much like the Previous Lord of the Nobles. He is also seen to be rather caring as he says that he is glad to see someone taking care of his friend, Cadis Etrama Di Raizel.
During his battle against Raizel, he was very violent, aggressive, and would not listen to reason. After getting help from Crombel, his aggression was diminished and he regained his reason.
After the loss of his daughter Ashleen, he holds humanity in a completely warped and distorted view.
Muzaka is the former Lord of the Werewolves before he was said to have betrayed them. It was also believed by many including his race that he was dead. At an unknown point in time, he met and befriended Rai. It is revealed that Rai stopped him from slaughtering all the humans and that is how their relationship was ruined. According to Rai, Muzaka lost something precious to him which ignited his wrath towards mankind. That precious being is Ashleen, the daughter Muzaka had with a human. After she was killed in a human-werewolf conflict(actually killed by a werewolf sent by Maduke), Muzaka set to wipe out the entire human race in his rage and agony when Rai fought him off.
The 9th Elder is seen entering a gigantic room where Muzaka is first seen immersed in fluid within a large experimental pod. The 9th Elder regretfully whispers that the Union may soon be in need of his power.
While fleeing from the Noblesse, Ignes Kravei decides to awaken Muzaka, in order to avenge her father's death by pressing a button in some sort of remote control. The tube which contained him instantly breaks apart and Muzaka is awakened. He then experiences a severe headache which causes him to emit a powerful scream, causing the lab to explode. Rai immediately recognizes Muzaka's aura.
During the battle, many things are revealed about him. In Frankenstein's memory, Muzaka often visited the Noblesse's Mansion Rai and that he also knew of Frankenstein, after being reported by his subordinate werewolves about him. Also, when Rai traps him in a Blood Field, he is fully awakened and it is revealed that his last memories were frozen in time during the fight against Rai 820 years ago. He also mentions something about Rai constantly stopping him from doing something. Later in the battle, it is revealed that Rai once stopped him from killing the humans and that is the cause of their previous battle.
Muzaka reveals his full power (which matches Rai's almost equally) and the two clash multiple times. With his magnificent claws, he manages to injure Rai severely and the two clash for the last time when Muzaka pounced at Rai to finish him off. However, Rai escapes with a slim victory and for unknown reasons, Muzaka's scent suddenly disappeared and even Frankenstein and Rajak could not detect his location. It's also predicted that he probably would not be able to move for a while after receiving a serious wound in the clash.
Muzaka's 'trace' is picked up by Dr. Crombel's assassins. Shortly afterwards, Muzaka falls a prey to Crombel's scheme, being lured by high-level agents right into Union branches. Muzaka engages at a war with the agents and exhausts unnecessary amounts of his power to annihilate them, gradually depleting his energy. After finishing about 1650 agents and obliterating 3 Union branches, he slows down due to his battle-worn state. Then Muzaka is approached by Dr. Crombel who greets him respectfully and he is surprised to learn that Crombel knows his identity. He tells Crombel to get lost when the latter calls him Lord of werewolves and mentions his revenge agenda. Crombel's comment that he has lost much of his memories irritates him further. However, Muzaka's attention is instantly arrested when Crombel mentions his reason of fury; his daughter. At this, Muzaka is visited by blurry visions of his daughter, Ashlyn. He cries out her name with tears gushing out through his eyes and goes into another fit recalling his past. This time, Crombel offers to help Muzaka achieve revenge if he agrees to go with him.
First is a flashback arc, showing the past of Muzaka and Raizel when they had first met. Muzaka, due to his wild and lonely nature, loved to wander away to different places leaving his pack behind. On one such occasion, he learnt about the existence of a powerful, lonely being amongst the nobles, called the Noblesse. He dismissed his follower, Garda who had been awaiting his arrival all along and ordered her against telling anyone of the pack about his return. Then Muzaka took a detour to the land of Nobles to meet the mysterious being. He found the Noblesse's mansion and entered it through the window right in front of Raizel. Instantly realizing the man to be the Noblesse, Muzaka introduced himself and shockingly found by the others expression that he was oblivious to his identity. The first meeting had to be cut short as Muzaka, sensing the presence of another visitor, left quickly through the window which he had used to come in.
Afterwards, Muzaka appeared in the werewolves' base and listened to the complaints of his pack regarding nobles interfering in werewolf activities. He opined that the nobles never interfered if it wasn't really necessary and asked his pack what they did to trigger such incident. Though most of his pack failed to find any decent answer, one of them (now known as the 2nd elder and current werewolf lord) took the initiative to convince Muzaka that they were just helping humans who asked for aid and it was the nobles who continuously poked their noses into werewolf business. He further proposed warning the nobles to stay clear of their activities rather they should engage in fighting the nobles instead. After realizing that the entire pack was sharing the mutual feeling and thinking through his options, Muzaka volunteered to meet the Noble Lord himself, much to the shock of his pack members. After they were dismissed, Garda remained to ask her master if he wanted to pay the visit for the sole purpose of addressing the issue. Caught off-guard, Muzaka admitted that he wanted to see his 'friend', the Noblesse - a very interesting person he had recently met.
Muzaka appeared through the same window of the Noblesse's mansion at night and found Raizel in the same position he had seen him first time. After a short explanation of his coming, Muzaka stood beside Raizel and commenting it was not his style, joined his friend in gazing at the bright, full moon.
Later, Muzaka appeared at the castle to meet the Noble Lord and after a warm welcome, he related his meeting with the Noblesse. The lord seemed glad to hear of a bond forming between such obviously different yet similar beings and finally notioned to start the serious discussions. Muzaka represented his pack's views on noble interferences and urged the noble lord to respect their actions, reminding the clear difference in standards of tolerance of both races. However, both the noble Lord's and Gejutel's account of his pack's direct participation in mass murder completely shocked him. Gejutel urged Muzaka to investigate his pack's actions, which they thought Muzaka had known all along. Upon learning that the incident from 12 years ago had also been the misdoing of his pack, Muzaka finally set off from the castle.
After reaching the base, Muzaka discussed with Garda, learning that she, also had known about the events and the pack being responsible for it but she never knew the particulars of actions until they were executed. Muzaka assumed that it was due to her loyalty towards him that the rest of the pack did not include her in any of their scheme. With this, Muzaka continued to fume in fury but Garda urged him not to confront the entire pack just for the sake of humans. After that, Maduke and his team arrive in front of Muzaka who demands an explanation of the incident the nobles had mentioned. Maduke tries to convince him that they didn't lie but as the conversation drags on, Muzaka realizes that his entire pack is against his viewpoint to not interfere in human affairs. Muzaka is furthered cornered with his own ideals when Maduke presents that they consented to 'help out' humans as per 'the request' of the humans Muzaka wanted to protect. Confused and uncertain what to do, Muzaka walks away from the pack with only Garda following him. Muzaka wondered how his pack came to harbor such cruel mentality and Garda tried to restrain him from deciding on a direct conflict. However, Muzaka wished for some private time and left his land again.
He visited Raizel yet again and talked about his travels. The bemused look on Raizel's face made Muzaka quite smug and he continued to describe the different places. At one point, Raizel started mistrusting all the info and Muzaka struggled to convince Raizel that he wasn't lying.
Muzaka resided in Raizel's mansion for about a month until he sensed the presence of a visitor and decided to leave. Suddenly, just when he was about to leave, he stopped to and ask his friend what he does when he has to make a tough decision. Upon continuous insist, Raizel replied that he did what he believed to be right. The statement left a strong impression on Muzaka as he jumped out of the window.
At the lair, Muzaka faced his pack again and clearly pronounced his decree: werewolves would only be allowed to interfere in human affairs moderately and any more incidents like the latest one would not be tolerated. Maduke stood up for the pack and tried to waver Muzaka's resolution but the werewolf Lord remained firm in his decision to not let the werewolves abuse their powers over humans. Muzaka further announced that it's a law all of them must honor as long as he was their Lord and should anyone have a problem with that, they might challenge him; he would have no problem if any of them beat him and did as he pleased. His resolution shocked the conspiring werewolves and Maduke likened him to nobles, asking the werewolf lord if he would be as mad as the Noblesse in case they committed a crime. The mention of his friend, the Noblesse, confused Muzaka and he was shocked to learn from Maduke how the Noblesse executed beings of his own race because they killed humans. While Maduke was implying that Muzaka was about to do the same, the latter realized the reason for his friend's loneliness and left his pack without a reply.
Muzaka casually hopped back into Raizel's room announcing his return while his friend simply stared at him. Lying down on the couch, Muzaka earned solace for himself, as he realized that his life was nowhere near as complicated as Raizel's.
The present time found Muzaka on the grounds of Ye Ran High School in a normal human outfit. His presence caught instant attention of Raizel. However, Frankenstein who is warned by the sensors reached him before his master. Muzaka assumed that Frankenstein has finally made up his mind to fight him. But before they could fix the right place, Raizel arrives and the two friends greet each other. Muzaka takes his friend for a private conversation. They sit down on a bench, gazing at the sunset while Muzaka assures his best friend that he'll not run wild like the last time.
After his meeting with Rai, it is revealed that it was Dr. Crompbel who showed Muzaka to Ye Ran High School and used the reunion to befriend him, identify Rai as the Noblesse and to deceive Muzaka into lending his body for his experiments. From then on, Muzaka meets Rai from time to time, although escorted by Yuri.
When Maduke engages a team of werewolves to assassinate Muzaka, Yuri leads them elsewhere with fake trails (as per Crombel's order) while Muzaka himself stands citygazing with Rai. But his quality time is cut short as Rai darts towards the area affected by Grui and Gaitan. As soon as the Noblesse leaves, Yuri appears and Muzaka learns from him about the assassins and how they have been thrown off-track.
Later Muzaka shows up at the island where Rai have been on the verge of confronting Grui and Gaitan for injuring his protegees. Muzaka engages in a power clash against Rai to stop him from interfering in his family related issues. Rai backs down when he is reminded that their power will blow away the injured kids in no time. Muzaka, then, faces the assassins sent to hunt him - Grui and Gaitan. He doesn't recall them from past and observes that they are in fact modified werewolves. Grui fangs at him for questioning their identities and call him a 'traitor' of the werewolf race. This incurs Muzaka's wrath. As the two assassins attack him, Muzaka slices down Grui into halves, transforming to his werewolf form in a fit of rage on Maduke who dared send only two minions to bring him down. Then he turns to Gaitan who challenges him with the enhanced power. Muzaka gives him the opportunity to display his potentials and goes on defense. However, he loses interest soon enough, finding Gaitans modified power boring. Muzaka then shows the power of a true werewolf and releases his wolf self to completely annihilate Gaitan. Having used the ultimate attack after a very long time, Muzaka feels a little exhausted and settles back onto the ground. He catches a worried look from Rai and asks him not to give that look. A sigh reveals that he regrets having killed a family member but he has known that it was coming sooner or later.
Just then, another pair of werewolves arrive and Muzaka recognize them as Lunark and Kentas - who were but kids when he had seen them last. After confirming from them that there were actually four assassins (including them) sent to kill him, Muzaka relishes the fact that his dignity is intact (Maduke did not insult him by sending only two).
Muzaka's contemplating moments are, however, cut short by Frankenstein's arrival. Muzaka is delighted to see even Frankenstein who is, on the other hand, enraged at those who injured his kids (Rael, Regis, Tao and Takeo). Muzaka clears up the misunderstanding to Frankenstein, saying that neither he nor the present werewolves had anything to do with harming the kids. When Frankenstein states that the two werewolves are their enemies and he has business with them, Muzaka steps up to protect his family members. He assumes Raizel will join since he has decided to fight but Frankenstein declares that he will be his only opponent. At this, Muzaka is quite excited since he has always wanted to fight the human who has surpassed the power of humans, one who is on par with clan leaders even before forming a contract with Raizel. However, Raizel reminds that there are injured kids around who might get hurt and the cherished battle gets nipped in the bud.
Muzaka then hurries his family members to leave. He gazes at their wake and wonders how much the little kids he once knew, have grown up. He turns to Raizel for farewell and both share worried looks for each other. Muzaka then glances at those around Raizel and acknowledges that his friend is not alone anymore. He then departs with a satisfied smile as he does not have to worry about Raizel like before.
Muzaka stands alone under a tree, breathing in the night air when Crombel approaches him. He has come to inform about Maduke's plan - the werewolves are on the move to attack Lukedonia. This news seems incredulous to Muzaka. He wonders if Maduke is in his right mind intending to fight the most powerful race in world. Crombel reminds him that things have undergone many change during these hundreds of years - the previous noble Lord has died, his successor is rumored of not being so capable, some ex-clan leaders have betrayed and joined forces with the Union and werewolves, the new clan leaders aren't much battle-experienced and currently there are only four clan leaders in Lukedonia. The werewolves and traitors have seized this opportunity to launch an attack. Hearing all this, Muzaka decides he needs a long breather and departs.
The scene shifts to a park near Ye Ran High School where Rai and Frankenstein are walking when Muzaka interecepts them. He brings them the news he heard about Maduke's plan to attack Lukedonia.
Thanks to Muzaka, Rai and Frankenstein are able to protect Lukedonia. Muzaka and Crombel discuss about the invasion. Muzaka says that Maduke's little scheme, whatever it was, must have failed. Crombel wonders why Muzaka didn't help his only friend (Rai). Muzaka tells him that Rai wouldn't have liked it as it was not his place to interfere. Besides, even after being betrayed by them, Muzaka did not feel like killing his own kind though he knows that his friend (Rai) doesn't have the same luxury.
Muzaka decides to wait for some more time before making his move.
At the start of season 8, Muzaka saves Yuri, Dr. Aris and Mark from M-21. A few weeks later he is contacted by Frankenstein in order to enquire about Werewolves' hideout as the Werewolves have captured M-21 .
Muzaka meets Rai and Frankenstein who keeps on asking him about the location of his clan members. Muzaka is reluctant to assist them, knowing well what they would do to members of the clan Muzaka once ruled. Their conversation is interrupted when Frankenstein learns that Lunark wants to meet him. Muzaka and Rai decides to let Frankenstein first meet Lunark.
Lunarks begs for a meeting with Muzaka from Frankenstein in exchange for M-21's location. Frankenstein fulfills her wish on the spot as Rai and Muzaka were nearby.
Muzaka asks Lunark why she wants to meet him. Lunark gets on her knees and begs for his help to free Kentas who is branded as a traitor. Muzaka is surprised but Lunark assures him that Kentas has not betrayed their race. She asks for his help as he was their Lord. Muzaka refuses her request, saying that he was not a good Lord; he suppressed his own kind for the sake of greedy humans and he now knows that his path as the Lord was wrong. He doesn't wish to interfere anymore in the internal affairs of their clan.
Lunark tries once more by informing him that their clan is sacrificing their own members for the sake of obtaining more powers through modification. The entire clan has underwent modification (with more than a few perishing in the process) except for Lunark and Kentas but Lunark is under pressure as well to accept enhancement. Frankenstein supports her claim of sacrificing werewolves as human modification technology can't be applied directly to werewolves as they are different species so experimental specimens are necessary.
Muzaka is shocked when he learns about Garda's condition. Lunark mentions how Kentas confronted Maduke about it but when he got no result he tried to find Muzaka and was thus marked as a traitor.
Muzaka, now infuriated at how low the clan he once reigned had sunken, vows to get revenge for Garda and help Lunark in rescuing Kentas.
Muzaka contacts Crombel to let him know that he won't be coming back to his lab for a while.
Muzaka, along with Rai, Frankenstein, and Lunark goes to the werewolves territory.
Muzaka is extremely powerful, being the former Lord of the werewolves. He was able to put the strongest being in existence, the Noblesse (who was in his weakened state when they fought) into a 820 year long slumber.
Like all werewolves, Muzaka can transform his body into a much larger, more muscular and overall a more wolf-like form. In this form; his claws elongate and become more blade-like, his entire body and eyes radiate a silvery glow, and his eyebrows turn extra-long with a horn-like curve. When transformed, his physical abilities and senses are greatly enhanced.
As former Lord of the werewolves, Muzaka still remains as the most powerful of all werewolves, as well as one of the strongest characters in the series. He possesses a vast amount of physical strength, shown in Noblesse: Beginning of Destruction when he lifts a massive bell and throws it at Rai. He is also extremely fast, being able to easily keep up with Rai and during his battle with Zaiga, he slices him into pieces with immense speed.
Claws: Muzaka's razor-sharp claws are able to create airborne kinetic shock waves powerful enough to destroy land for miles. Muzaka can imbue his claws with his aura, giving them the power to cleave a large mountain in half and blow away a large forest, causing an earthquake. He can also create deep fissures in the ground that spread for miles across a mountain range. This display of might is enough to cause Kentas, Frankenstein, Lunark, and Rajak to tremble in fear.
Sonic Howl: Muzaka can produce ultrasonic shock waves with his howls and screams. They have enough power to cause a large research facility, and the surrounding forest to explode and shake the surrounding mountains. He also uses this technique against Rai's Blood Field, and was able to disperse it with ease.
Regeneration: Although werewolves possess superior regenerative powers compared to Nobles, Muzaka's is in another league. In Noblesse: Beginning of Destruction, when his arm is severed by Rai, he heals it in mere seconds. He was able to completely heal from having crashed into the ground from a high altitude by Rai's devastating attack, having his broken bones, eviscerated muscles and internal organs exsposed. Ignes also testified that no matter how much she physically broke him he always managed to heal quickly. According to Muzaka, most likely due to his battle with Rai 820 years ago, his regeneration power has decreased greatly. Although his regeneration power is weaker compared to when he was Lord, it still remains on a very powerful level shown when it stops Frankenstein's powers from further spreading through out his body, stating that since his regeneration is so powerful it would have been fatal for anyone else.
As former Lord of the werewolves, Muzaka possesses an immense amount of spiritual energy (aura). His transformation releases enough aura energy to cause the surrounding mountains to shake. He has shown to be very skilled at manipulating his aura, shown in his battle with Rai in Noblesse: Beginning of Destruction when he creates a giant claw made purely out of his aura to counter Rai's attack. He is able to utilize his clans most powerful attack on a massive scale, that only few members can use.
