Feng Kowloon is a major character from the manga series Undead Unluck, a Chinese martial artist and Negator belonging to the organization UNDER, known for his ruthless pursuit of absolute martial supremacy and his ability UNFADE (Negator of “aging”).
He is first introduced as a mysterious hooded fighter and later revealed to be the master and killer of Shen Xiang’s sister, as well as one of the most dangerous combatants in the setting.
Feng Kowloon is a member of UNDER, originally branded as a group that hunts Negators.
He is a battle-obsessed Chinese martial artist who lives solely to fight strong opponents and prove himself “peerless under heaven”.
Despite his often calm or laconic demeanor, he radiates a lethal, unsettling presence.
He speaks only Chinese even after language unification, strongly indicating his Negator status and adding to his air of isolation.
He is a master of a self-created style called True Bajiquan, an evolved, original martial art that has been polished over more than a century.
Even without relying on his Negator ability, he stands among the absolute top tiers of physical fighters in Undead Unluck.
Feng is also an avid artifact collector, focusing mainly on weapon-type ancient artifacts and using them to further enhance his already monstrous combat ability.
His joining UNDER is based on a clear condition: information sharing and access to ancient artifacts, especially those related to youth and time.

At his first appearance, Feng wears a Chinese-style hoodie with the UNDER emblem and an inverted “misfortune” symbol combined with the characters for “Eight Extremes,” hiding his face under a hood.
This creates a strong visual of a small, dangerous, anonymous Chinese fighter stepping into the black market.
Before he uses the artifact to regain his youth, he appears as a frail-looking elderly man in his seventies, belying his true strength.
After the artifact’s effect, he reverts to his prime: a young adult with a lean but extremely muscular build, sculpted by more than a century of relentless training.
His youthful face is sharp and predatory, exuding malice and confidence.
He has a mole on his forehead, distinctive eyebrows that fork at the ends, and long hair braided into a single plait.
A strand of hair falls over his forehead, with symmetrical tufts flaring outward from his sideburns, adding to his unique silhouette.
Overall, he looks every inch the “evil master” type: elegant, intense, and clearly dangerous.
Feng is a hyper-pure combat addict, even more extreme than his battle maniac disciple Shen Xiang.
He sincerely lives for battle with the strong and views the end of the world as just another exciting opportunity to fight gods.
He is fully prepared to let Ragnarok arrive if it means a chance to clash with a divine enemy.
When he talks about this, he often wears an eerie smile not of malice alone, but of genuine anticipation and joy.
Morally, Feng is an outright villain and extreme egoist.
He holds the philosophy that “to become truly strong, you must lose what you love and be filled with hatred and despair,” and he attempts to force this worldview onto others.
To “train” his disciples into stronger warriors, he is willing to destroy everything they care about.
He does not hesitate to try to kill Fuuko Izumo or Mui solely to make Andy and Shen Xiang stronger through grief.
His idea of mentorship is twisted: he takes in talented disciples, nurtures them until they become strong enough to challenge him, then plans to kill them himself.
In his own words, disciples are merely “nourishment” for his own path to peerless strength.
Despite all this, later developments reveal a buried complexity:
his actions sometimes betray a subconscious attachment to his disciples and a latent capacity to change, especially as he confronts the limitations of “strength for oneself alone.”
Feng is the martial arts master of Shen Xiang, a Union fighter, and the man responsible for the death of Shen’s sister, Mei Xiang.
In Shen’s childhood, Feng took in Shen and Mei, both orphans, and became their teacher and guardian.
However, Feng’s affection was warped by his ideology.
He orchestrated a horrific scenario where Shen and Mei would be forced to fight to the death, aiming to use Shen’s resulting despair as fuel for further strength.
When Shen’s senior disciple and Feng’s first disciple, Luo, tried to stop him, Feng killed Luo without hesitation.
This cemented him as Shen’s hated nemesis and the core trauma of Shen’s past.
At that time, Feng was physically an elderly man in his seventies, already in possession of UNFADE, making him chronologically around 170 years old.
As his body aged, he became increasingly frustrated that although he sought absolute strength, his physical vessel was deteriorating with age.
Unable to accept that contradiction, Feng became obsessed with youth-related artifacts.
He joined UNDER under the condition that they help him find and share information on ancient artifacts, especially those capable of reversing age.
During the black market auction storyline, Rip Tristan obtains the artifact Life Is Strange, a time-manipulation device.
Feng uses it to rewind Rip’s time and resurrect him, deliberately setting the rewind wide enough that the “10x backlash” effect lets Feng himself regress about 150 years in biological age and return to his prime.
From that point on in the original loop, Feng appears in his youthful form.
Shen only realizes that this hooded, youthful fighter is the same master he has been seeking revenge on when Feng’s identity is fully exposed.
Feng calls himself “peerless under heaven,” and his feats strongly back that up.
His power is fundamentally based on pure martial arts and physical prowess, not on his Negator ability.
Some of his notable feats include:
Damaging Tatiana’s BM armor with a single barehanded strike, even while in his elderly body.
Casually catching Andy’s Vortex Fist (Kou-Ka-Ken), a spiral punch powerful enough to pierce even Victor, and smiling while doing so.
Neutralizing a surprise attack from Mui behind him with a no-look backward kick.
Overwhelming a fully-trained Shen Xiang in a one-on-one battle, showing a clear gap between master and disciple.
Instantly understanding the weak point of Andy’s Undead ability, dislocating both Andy’s arms in a way that bypasses his usual regeneration advantage.
Catching a revolver bullet with his toes.
Dodging Andy’s close-range Radius Bone Pile surprise attack as though it were nothing.
Creating new techniques on the fly in the midst of god-level battles, such as integrating absolute zero conditions into a new kick technique.
All of this is explicitly described as non-supernatural martial prowess.
Even Andy initially suspects Feng must be using a power, but it is simply the product of centuries of obsessive training.
With his artifacts on top, Feng becomes one of the greatest solo combat threats in the setting.
He is a walking cheat code: brutal, efficient, and technically brilliant.
UNFADE is a self-target, forced-activation Negator ability that denies the user’s aging.
From the moment the ability transfers to a person, their body no longer ages physically.
This means:
The user does not grow older anymore from that point forward.
Natural aging and death from old age are denied, but the user is still fully capable of being killed by injury.
In other words, UNFADE is a kind of “inferior version” of Andy’s UNDEAD.
The user is still mortal in battle, but they never die through simple old age or aging-related decline.
In Feng’s case, UNFADE transferred to him when he was in his seventies.
At that time he was at a stage where his mind and technique had reached great heights, but his body was clearly declining.
He admits that he used to look at the young with jealousy and resentment.
UNFADE removed his aging, but only from that old state onward.
As a result, his real chronological age in the main story is around 170–180 years.
Aside from Andy (and Victor and a few special cases), he is one of the oldest known individuals.
Because of UNFADE, if he uses Life Is Strange and the backlash causes him to "age forward," that aging is negated.
However, if the backlash causes him to become younger, that change is accepted – hence his successful 150-year physical regression.
This also implies he could, in theory, use Life Is Strange offensively on others to age them explosively while suffering no aging side-effect himself, due to UNFADE.
He effectively turns time manipulation into an almost no-cost weapon in the right circumstances.
Feng’s martial art is his own original style, later named True Bajiquan.
When Shen first became his disciple, the style did not even have a name; it was simply Feng’s personal path of martial evolution.
Core Techniques
Hakkai Zankou (Back Mountain Crash)
Often described as an evolved form of the classical “Iron Mountain Lean” body-check.
Feng uses his entire body like a battering ram, slamming with his back or shoulder with massive internal force.
This technique is so iconic that Shen Xiang also uses it as a key move in his own fighting style.
It embodies the close-range, explosive power focus of True Bajiquan.
Koboku (Arc Strike)
Feng lightly presses both hands onto his opponent, seemingly gently, before releasing a wave of internal force that can blow two adults away simultaneously.
When Andy takes this strike, he has to use his undead regeneration to contain the shock inside his own body to protect Fuuko Izumo on his back.
Even so, Andy’s internal organs and tissues are heavily damaged, and his clothes are torn apart from the internal shock alone.
Feng’s step-in footwork is so powerful that the ground itself cracks beneath his feet for many of his techniques.
Zesshou Hoho (Step Cannon Fist)
Feng closes medium distance with a single explosive step, then hammers a side fist (akin to a collapsing fist) straight through the target.
When this hits Andy, it punches clean through his torso, displaying enormous penetrative power.
The combination of footwork, timing, and structural mechanics makes this technique extremely difficult to block or evade once the distance is closed.
It is a perfect example of his “nothing wasted” fighting style.
True Bajiquan as a Path
Feng’s entire martial philosophy is built on continuous evolution.
He constantly refines, reinterprets, and expands his techniques, integrating new experiences—including fighting gods and artifacts—into his style.
Later in the story, he even develops Kuon Shinkon Ha (Eternal True Soul Wave), considered the completed ultimate secret of True Bajiquan.
This technique emerges at the moment he confronts death and rebirth as a path to higher strength.
Feng collects ancient artifacts, especially those with combat applications.
These relics significantly enhance his already tremendous power and give him frightening versatility.
Suishin Tetsukan (Will-Following Iron Staff)
Suishin Tetsukan is a hexagonal rod with an internal chain, an artifact that can extend, retract, and transform into multiple forms.
It has at least four forms, numbered “one” to “four,” each altering its structure.
Form One: A staff.
Form Two: Nunchaku-style dual sections.
Form Three: Three-section staff.
Form Four: An advanced form Feng himself never fully mastered.
Each form is said to have its own secret technique.
The one shown in the series is likely the staff-form ultimate: Ryu En Bu (Dragon Flame Dance).
In Dragon Flame Dance, the staff becomes wreathed in dragon-shaped heat energy, and Feng hurls it as a devastating projectile.
The attack can pierce through the stomachs of two adults in a single shot, with the staff’s sections floating and separating mid-air.
After Feng’s defeat, Shen Xiang later uses Suishin Tetsukan as his weapon.
The artifact’s name is likely a reference to “Will-Following Iron Staff,” a weapon parallel to the famed Ruyi Jingu Bang in Journey to the West lore.
Death Game
Death Game is a bead-like rosary artifact worn as a bracelet or necklace.
Any person killed by the bearer can have their soul captured and their body resurrected as a jiangshi (Chinese hopping corpse) under the artifact’s control.
The resurrected jiangshi has no pain and cannot act without explicit orders from the Death Game’s wielder.
Feng has been using Death Game since before joining UNDER, sealing his first disciple Luo and multiple other masters from rival schools into the beads.
During the story, Fuuko Izumo manages to steal Death Game from Feng while fighting him.
It later ends up in Mui’s hands, who uses it to sustain a jiangshi version of Shen.
Black Cloud
Black Cloud is a black cloud-shaped artifact matching the legendary Golden Cloud in form, but its properties are darker and more sinister.
It serves as a flying mount for the user, carrying them through the sky.
From its portrayal, it seems to respond to users with malice or ill intent.
It likely mirrors Golden Cloud’s requirement of purity inversely, accepting a corrupted heart instead of a pure one.
Life Is Strange
Life Is Strange is a small sphere resembling a mechanical pocket watch.
It can accelerate or reverse the time of a chosen target, effectively aging or de-aging them.
However, the user must pay a steep cost: the user experiences 10 times the time shift applied to the target.
If they rewind a target by 5 years, the user is rewound or advanced by 50 years.
Rip Tristan uses this artifact when near death, with Feng assisting.
Rip is rewound about 15 years into childhood, while Feng uses the backlash to rewind his own body roughly 150 years, regaining his youthful prime.
Because Feng is a UNFADE user, the aging-forward side of the backlash can be nullified by his ability, but the de-aging part can take effect.
This synergy makes Life Is Strange, in Feng’s hands, both a resurrection tool and a personal rejuvenation device.
In the original loop, Feng first appears as one of the intruders at a black market auction.
He is introduced as a quiet but ominous Chinese fighter, shrouded in a hoodie, whose language barrier and silence add to his menace.
During the black market arc:
He displays overwhelming raw power by cracking Tatiana’s BM armor with a single strike even as an old man.
He nearly kills Andy and Shen Xiang, repeatedly exploiting their weaknesses and attempting to murder Fuuko Izumo and Mui to “sharpen” them.
Feng’s obsession with artifacts leads him to use Life Is Strange on Rip Tristan.
Rip’s time is rewound, reviving him, while Feng uses the backlash to become physically young again.
When Shen finally confronts him, he discovers that the youthful Feng is in fact his old master and the murderer of his beloved sister Mei.
Their battle is a brutal reunion where Feng tries to push Shen into even deeper despair.
Later, during the fight against UMA Summer in Taiwan, Feng faces:
Jiangshi Shen Xiang, now controlled via Death Game.
Mui, whose own ability Untruth (Negator of “truth”) is awakened and activated.
Through a combination of Shen’s fighting, Mui’s Untruth, and their allies, Feng is at last defeated.
He is taken into Union custody and imprisoned.
Imprisonment and Subtle Change
While imprisoned, Feng remains obsessed with strength and continues training.
When UMA Ghost is added to the world, soul-related techniques become possible, and Feng eagerly dedicates himself to mastering spiritual perception.
During an interlude, he is interrogated by Mui and the jiangshi Shen.
In a seemingly offhand gesture, he hands over Suishin Tetsukan to Shen, saying that otherwise the weapon will “rot,” subtly acknowledging Shen’s growth.
During Ragnarok, when the gods assault the world, Feng actually assists Shen and Mui.
He fights against the gods’ attack, aligning himself temporarily with his former enemies purely for the joy of challenging such overwhelming power.
In one quiet but powerful scene after UMA Summer’s defeat in Taiwan, Shen, Mui, and the jiangshi Shen float on Golden Cloud, with the battered Feng slung over the undead Shen’s shoulder.
Shen recalls a summer long ago when he, Mei, Luo, and Feng watched fireworks together and felt, just for a moment, like a family.
Shen asks whether Feng ever thought of them as family.
Feng coldly replies that he never considered them family even once, that they were merely fuel for his own growth and nothing more.
However, Untruth is active, and Mui sees through this.
Shen, with tears that continue to flow even in death, understands that Feng’s words are a lie, and that on some level, Feng did see them as more than just tools.
After the loop reset, Feng reappears in a different timeline with a different history.
This version of Feng is still a Negator of UNFADE, but his ability manifested when he was already at his absolute physical peak.
In the new loop, Feng has already reached the pinnacle of martial arts when UNFADE awakens.
As time passes, however, all his rivals and worthy opponents grow old and fade away, while he alone remains in his prime.
This leaves him trapped in an eternal youth where no one can push him anymore.
His wish—to endlessly fight strong opponents—becomes impossible to fulfill as everyone else ages and weakens.
When Fuuko Izumo appears and quickly grows strong, even mastering True Bajiquan, Feng finally finds an opponent who can defeat him.
He fights Fuuko multiple times and loses, leading him to develop an intense fixation on her.
Summoned by Misfortune
At one point, Fuuko attempts to capture UMA Heat by attaching her misfortune.
The backlash of that misfortune summons Feng as the “unlucky” result.
He immediately incapacitates Heat with a single blow, showcasing just how terrifying his power is.
He then confronts Fuuko again, only to be defeated once more by the combined power of Unluck and True Bajiquan.
Fuuko, instead of killing him, demands a promise:
Feng must meet, train, and raise Shen Xiang as his disciple.
After extracting this promise, she lets him withdraw.
Feng, driven by both resentment at his defeats and curiosity about Fuuko’s strength, agrees and disappears.
True to his word, Feng finds young Shen Xiang and Mei Xiang and raises them from childhood.
For years he trains Shen in martial arts while also taking care of Mei’s daily needs.
Because Fuuko also imposed a non-killing condition—Feng must not kill people before each rematch—he is unable to unleash his full savagery.
He has to change diapers, cook, and manage domestic life, all while wanting to fight.
This situation enrages him: the strongest martial artist in the world is stuck doing childcare and household chores.
When he crosses paths with Fuuko again at the great martial arts tournament Tensai Festival, he vents his frustration, and even Fuuko can’t help but sincerely say, “You’ve worked hard.”
The Tensai Festival is a grand tournament to decide the world’s strongest martial artist.
Feng appears as the reigning champion, having won the previous tournament.
Fuuko and her allies participate in order to recruit Shen Xiang.
Feng is delighted to see them, thrilled at the prospect of another clash with Fuuko and a chance to show off his disciple.
During the tournament, Shen awakens his own Negator ability Untruth.
Feng and Shen eventually face each other in a father-son-like showdown.
In this new loop, Shen genuinely respects and loves Feng as a foster father and teacher.
He has grown strong through the joy of “becoming strong for someone else” instead of sheer hatred.
During their fight, Feng declares that when he gained UNFADE, no tragedy accompanied it, implying that his power came without the usual Negator curse.
Shen counters by pointing out the hidden tragedy: because of UNFADE, Feng has been trapped in eternal youth, forced to watch every rival grow old and die while he remains alone.
Shen insists that this is its own kind of suffering and emptiness.
He demands that Feng look at him, not as food, but as the son who will surpass him.
“Look at me! I’m the man who will surpass you!” Shen effectively cries.
“Be an old man and be proud of your son’s growth!”
In the ensuing clash, Shen lands a decisive blow, sending Feng flying out of the ring.
Due to Untruth, which only affects those Feng holds some affection for, Feng is stopped in his tracks, revealing that he does indeed care about Shen.
In that moment, Feng finally recognizes the joy of passing strength on to another and the warmth of seeing his disciple as family.
He calls Shen “impressive, you idiot son”, acknowledging him as his child in all but blood.
After being defeated, Feng no longer has a duty to raise Shen as per Fuuko’s original order.
He attempts to leave, but Fuuko pulls him into yet another mission.
Fuuko recruits Feng to help with a difficult mission that involves infiltrating a high school.
Feng is ecstatic at the prospect of facing strong enemies and fighting gods and UMAs again.
To his horror, the “mission” requires him to work as a PE teacher at a high school for a year.
Fuuko and the others trick him into a normal teacher’s life: taking attendance, running classes, dealing with students.
He rages at Fuuko for “betraying” him.
However, Shen’s Untruth often forcibly compels him to cooperate, making him a reluctant but effective faculty member.
At one point, during the graduation ceremony, the UMA Color attacks.
Feng charges in, ready to unleash his built-up frustration through violence.
But Color uses transformation to copy the appearance of the student Ryo.
Previously, Feng would have killed without hesitation, but now, as someone who has spent a year as a teacher, he finds himself unable to strike Ryo’s stolen face.
He is confused and angry at his own hesitation, not fully understanding how much he has changed.
After the battle, when the students take a final group photo, Feng tries to escape, but ends up stuck halfway through the ceiling, forced into the picture anyway.
Later, during the battle against UMA Language, the heroes engage in a deadly world-scale word-chain (shiritori) game.
To gain more firepower, they exploit the rules: using the word “Unfade” in Uzbek to summon Feng.
He arrives mid-battle, still obsessed with powerful opponents.
Sean Datz transfers his accumulated points to Feng, making Feng a Union Seat Ten member.
Language summons a false dragon god using the new rules.
Feng promptly fights and defeats the dragon through pure martial arts, which amazes and horrifies Nico Vorgeil and Icho, who realize he is both a great asset and a huge liability.
Language notes that while Feng is an excellent weapon, he is far from a reliable ally.
The enemy then escalates to Phase 3 in the word-chain rules and ultimately summons Sun (Sol) and Moon (Luna).
Feng, thrilled by these god-like opponents, tries to charge in alone.
Nico physically restrains him, pointing out that there is zero margin for error and that rash moves will doom everyone.
Feng urges them to sacrifice one ally to turn Nico into the Negator Unremember (Not-Forget), which would require killing Fuuko.
To Feng, a single sacrifice for greater power is a simple, logical step.
Nico rejects this, and in arguing, he convinces even Feng to rethink his approach.
He confronts Feng with the truth: that fighting “for others” produces a different, even greater kind of strength than fighting only for oneself.
This conversation has such impact that Feng, for the first time, calls Nico by name and actively cooperates.
He works in tandem with Nico and the others, allowing Nico to freeze the pseudo-Sun and then combining that condition with a new aerial kick technique.
Language, realizing that Feng has become too dangerous to leave alive, decides to target him for death.
The battle reaches a point where Nico and Icho plan a strategy requiring Feng to die once.
The plan involves making Nico into Unremember temporarily and using the rules of the game and resurrection.
At first, Feng resists the idea of dying for others, but when Nico vows to resurrect him, his perspective flips.
If death itself can become a stepping stone to a higher form of strength, Feng suddenly becomes eager.
He laughs, proclaiming that he will use Nico’s Unremember as a stepping stone for his martial path.
This leads to the birth of Kuon Shinkon Ha (Eternal True Soul Wave), the completed secret technique of True Bajiquan.
He takes a direct hit from pseudo-Sun’s Balmung-like attack and dies.
Nico then uses the language rule:
“Reanimatsiya” – resurrection in Uzbek – to bring Feng back.
Upon revival, Feng unleashes Kuon Shinkon Ha, annihilating pseudo-Luna and proving that even death serves as raw material for his ever-evolving martial arts.
From that point on, Feng is no longer just a solitary monster chasing personal glory.
He is a reluctant but genuine member of the wider effort, still a lunatic battle junkie, but one who now understands—if only partially—the power of fighting for others.
