Phobio is a high-ranking officer of the Beast Kingdom Eurazania and one of its strongest fighters, standing alongside Albis and Suphia as one of the Three Beastketeers.

He first appears as an envoy sent to the newly founded Federation of Jura Tempest after Rimuru Tempest defeats the Orc Lord and unifies the Great Jura Forest.

Despite his formal position, Phobio initially behaves arrogantly, causing diplomatic trouble and being judged unfit as an envoy by Rimuru.

His resentment is then exploited by Clayman and the Moderate Harlequin Alliance, leading to one of the early large-scale crises in the story.

Envoy to the Federation of Jura Tempest

Hearing that Rimuru Tempest has defeated the Orc Lord and established the Federation of Jura Tempest, the Beast Kingdom Eurazania decides to send a delegation.

Phobio is chosen as the envoy, accompanied by subordinates such as the monkey beastman Enrio, and arrives with the mindset of a warrior nation built on “survival of the fittest.”

When Rigurd comes out to receive him, Phobio immediately punches Rigurd in the face, gravely injuring him.

He does this to “prove the difference in rank” and force the Tempest side to submit through intimidation rather than diplomacy.

However, Milim Nava, who is staying in Tempest as Rimuru’s “best buddy,” witnesses this assault.

Incensed that one of her friend’s subordinates has been attacked, Milim knocks Phobio out with a single punch, effortlessly defeating him.

Afterward, Rimuru formally meets Phobio and criticizes his lack of sincerity and self-control as an envoy.

Phobio is expelled from Tempest and told that if Eurazania wishes to establish formal relations, they must send a proper envoy, effectively stripping him of his mission.

Manipulation and the Charybdis Incident

Humiliated and frustrated, Phobio camps with his troops in the Great Jura Forest, harboring resentment toward Milim and Tempest.

During this vulnerable period, two masked clowns from the Moderate Harlequin Alliance—including Tear and Footman—approach him with a tempting offer: a chance to strike back at Milim Nava.

Blinded by anger and pride, Phobio accepts their proposal, failing to notice that he is being used as a pawn in Clayman’s greater scheme.

He resigns his official status and orders his subordinates to return home and report everything to Karion, trying at least to ensure Eurazania will not be implicated.

The clowns transform Phobio into the vessel for Charybdis, a catastrophic monster.

In this form, he becomes a massive threat rampaging across the Federation of Jura Tempest, forcing the nation to mobilize its forces.

Charybdis is ultimately defeated not by brute annihilation, but by the intervention of Milim Nava, who has learned to “hold back” her power.

Milim carefully attacks without destroying Charybdis’s core, allowing Phobio’s body—serving as the nucleus—to be extracted intact.

Thanks to this, Phobio narrowly escapes death and survives the incident.

Reconciliation and Renewed Diplomacy

After learning about the full incident, Karion himself visits the Federation of Jura Tempest.

He publicly reprimands Phobio (including a physical punch) for his recklessness and apologizes to Rimuru’s nation for the trouble caused.

Karion’s sincere apology and the resolution of the Charybdis crisis lead to a proper establishment of diplomatic relations between Eurazania and Tempest.

Phobio’s actions leave Eurazania in debt to Tempest, but they also mark the beginning of genuine cooperation between the two nations.

Phobio, having survived and recognized the scale of his failure, begins staying in Tempest for a time.

There, he witnesses the power and organization of the federation firsthand, correcting many of his earlier prejudices.

Role in the War Against Clayman

Phobio later reappears in the great conflict between the Federation of Jura Tempest and the forces of Clayman.

Now fighting as an ally of Tempest, he leads troops as a commanding officer in the combined Tempest–Eurazania alliance.

During this war, he fights alongside Geld, the new leader of the orc race and a high-ranking official of Tempest.

Phobio had previously looked down on orcs, but after seeing Geld’s capabilities and the discipline of the orc warriors, he acknowledges them as true comrades-in-arms and highly capable fighters.

Together with Geld, Phobio engages and suppresses Footman, one of the clowns who once manipulated him.

After the successful operations, the two commanders recognize each other’s skill and effort, strengthening the bond between their nations.

Defense of Eurazania and Postwar Duties

Following the battle against Clayman, Phobio returns to the Beast Kingdom Eurazania.

He takes part in the defense against Clayman’s forces when they attempt to strike Eurazania, and he faces Tear once again in this campaign.

After the war, Eurazania suffers damage and political upheaval, requiring reconstruction and management of prisoners of war from Clayman’s army.

Phobio remains in his homeland with Geld, who is dispatched to assist, and takes on the responsibility of monitoring captured demon-style subordinates and helping rebuild the country.

The Benimaru–Albis Marriage Operation

Later, Phobio is roped into a “plan” involving his colleague Albis and Benimaru from Tempest.

The goal is to arrange and test the suitability of Benimaru and Albis for marriage through a brutal but controlled combat trial in Ramiris’s labyrinth.

Phobio is forced into acting as a key participant in this operation.

He secretly harbors romantic feelings for Albis and sees this as his chance to win her hand instead.

A condition is set: if Phobio can defeat Benimaru in the labyrinth, he will be allowed to marry Albis himself.

Taking this seriously, he challenges Benimaru with all his might in a life-or-death style duel inside the dungeon.

Despite his determination and considerable power, Phobio is decisively defeated by Benimaru.

The loss crushes his hopes and leaves him heartbroken, particularly once Benimaru’s strength and Albis’s genuine feelings become undeniable.

Connection with Gobwa

By volume 14 of the novel, Phobio’s failed love for Albis finds a strangely parallel echo in Gobwa, a female ogre who also experiences heartbreak related to Benimaru’s relationships.

Gobwa, originally a goblin who evolved into an ogre out of admiration and love for Benimaru, is forced to face reality when she witnesses the power and presence of Benimaru’s fiancée Momiji and Albis.

Both Phobio and Gobwa are left nursing broken hearts after the marriage arrangements surrounding Benimaru.

Through this shared experience, they grow closer, developing a rapid and surprisingly warm connection that hints at further development in their relationship.

Later Career: Flying Beast Knight Order

By volume 19, after Karion’s awakening and the reorganization of Eurazania’s forces, Phobio becomes the vice-commander of the Flying Beast Knight Order.

This unit is a formidable aerial force composed of beastman riders, and Phobio’s appointment reflects both his strength and his growth in judgment and leadership.

He now operates not just as a frontline bruiser but as a seasoned commander, embodying the lessons he learned from the Charybdis disaster and the wars that followed.

His loyalty to Karion remains absolute, but his perspective is broader, and he works more closely than ever with Tempest and its allied nations.

At his introduction, Phobio appears as an overconfident, hot-headed thug in a high position, often acting like a small-time bully despite his elite status.

He is quick to resort to violence, easily provoked, and inclined to look down on those he assumes are weaker—especially those outside the warrior culture of Eurazania.

However, this impression only reflects one side of his character and his relative youth among the Three Beastketeers.

At his core, Phobio is actually a capable statesman and soldier: he can calmly assess situations, read intentions, and admit his mistakes when confronted with undeniable evidence.

He is deeply loyal to Karion, his lord, and genuinely cares about his subordinates, earning their trust in return.

Even when succumbing to the clowns’ temptations, he resigns his position and sends his men home, trying to ensure that Eurazania and Karion will not be held responsible for his personal revenge.

Phobio’s flaws are closely tied to the unwritten “survival of the fittest” law among beastmen.

This culture teaches that “the strong rule all,” leading him to stubbornly refuse to accept the strength of Tempest’s residents at first, because doing so would feel like betraying beastman pride and status.

The Charybdis incident and his humiliating defeat by Milim Nava act as hard lessons.

Afterward, he is harshly disciplined and deeply reflects on his behavior, striving to become more level-headed and true to his innate chivalrous and honorable nature.

By the time of the later story arcs, Phobio has matured into a far more sympathetic and likable figure: still passionate and straightforward, but more self-aware, respectful, and capable of genuine cooperation.

He respects strength wherever he finds it, whether in orcs like Geld, allies from Tempest, or his fellow beastmen, and no longer lets pride blind him so easily.

Phobio’s combat power is at a quasi Demon Lord level, which is why he holds a position among the Three Beastketeers.

Early on, his raw power even exceeds that of Benimaru, though the gap reverses as Benimaru continues to evolve and grow.

As a black panther beastman, Phobio specializes in high-speed, close-quarters combat with exceptional agility and physical strength.

He is well suited to both shock assaults and extended battles, making him a versatile frontline fighter and commander.

During the Charybdis incident, serving as the core vessel for Charybdis alters his abilities.

His skill Self-Regeneration evolves into Ultra-Speed Regeneration, granting him near-immortality so long as his magic power is not exhausted.

With Ultra-Speed Regeneration, Phobio can ignore most damage and drag fights into endurance contests that heavily favor him.

This toughness, combined with his physical prowess, makes him extremely difficult to take down without overwhelming power or strategic advantage.

Even after being freed from Charybdis, this evolved regeneration remains, significantly boosting his survivability in later battles.

Combined with his experience commanding troops against Clayman’s forces and in Eurazania’s defense, he stands among the top mid-to-high-tier powerhouses in the series’ world.

Karion

Karion is the Beast King of Eurazania and one of the Ten Great Demon Lords (later part of the Eight Star Demon Lords).

Phobio swears unwavering loyalty to Karion, respecting him as both a sovereign and a warrior.

When Phobio is saved after the Charybdis incident, Karion personally arrives, punches him once as punishment, and apologizes to Tempest on his behalf.

This event deepens Phobio’s sense of responsibility and gratitude, pushing him to grow and to live up to the trust Karion continues to place in him.

Albis

Albis is Phobio’s colleague in the Three Beastketeers and the de facto leader among them.

She is a snake beastman with the epithet “Yellow Horned Serpent,” and her strength is such that ordinary demon-class fighters cannot touch her.

Phobio respects and admires Albis professionally, but he also secretly falls in love with her.

This hidden affection becomes crucial during the Benimaru–Albis marriage operation, when Phobio is given a chance to win her hand by defeating Benimaru.

He goes all out in that battle, not as a mere test, but with genuine intent to become Albis’s husband.

His defeat, however, ends those hopes and leaves him emotionally crushed, though he ultimately accepts the result and continues to support Albis.

Suphia

Suphia is another member of the Three Beastketeers, a white tiger beastman who acts as Phobio’s rival.

The two constantly push each other, comparing their strength and vying for status within the trio.

When Phobio commits his initial blunders, Suphia harshly scolds him for dragging Eurazania’s name through the mud.

However, when Karion later goes missing due to Clayman’s scheme, Suphia becomes emotionally shaken, and Phobio, together with Albis, helps calm and encourage her.

This shows that beneath their rivalry, the Three Beastketeers share genuine mutual trust and regard each other as irreplaceable comrades.

Milim Nava

Milim Nava is one of the Ten Great Demon Lords (later one of the Eight Star Demon Lords) and, indirectly, the cause of much of Phobio’s early misfortune.

She is the one who knocks him out with a single punch when he injures Rigurd, and her overwhelming power makes any revenge attempt unrealistic.

Later, the Beast Kingdom Eurazania ends up under Milim’s influence, effectively making her Phobio’s superior.

Ironically, the person he once resented becomes part of the higher command structure he must obey, though by then he has gained enough maturity to accept this reality.

Geld

Geld is the son of the former Orc Lord and the new leader of the orc race, serving as an important official in the Federation of Jura Tempest.

At first, Phobio is prejudiced against orcs and sees them as inferior trash.

The joint Tempest–Eurazania campaign changes this perception completely.

Fighting side-by-side with Geld as co-commanders, Phobio witnesses the orcs’ discipline, courage, and Geld’s tactical prowess firsthand.

Together, they successfully restrain Footman and contribute significantly to the campaign’s success.

After the war, Phobio sincerely respects Geld as a warrior and ally, and they collaborate again during Eurazania’s reconstruction, even living there together for a time to manage reconstruction and prisoners.

Enrio

Enrio is a monkey beastman who serves as one of Phobio’s subordinates during his first appearance.

Unlike his hot-blooded commander, Enrio is cautious and often acts as a voice of reason, trying to restrain Phobio’s impulsive decisions.

When Phobio decides to accept the clowns’ offer and become Charybdis’s vessel, he dismisses himself from his official post and orders Enrio and the others to return home.

He entrusts Enrio with reporting everything to Karion, showing his trust in Enrio’s reliability and judgment.

Later, Enrio becomes responsible for trade with the Federation of Jura Tempest.

He introduces the dog-headed beastman Koby as a negotiator, further strengthening economic ties between the nations.

Gobwa

Gobwa is an ogre woman from the Federation of Jura Tempest, originally a goblin who evolved into an ogre out of admiration and love for Benimaru.

She gains enough strength and trust to be appointed as the leader of Benimaru’s direct unit, the “Crimson Flame Corps.”

During the arrangements for Benimaru’s marriage, Gobwa confronts the reality of Benimaru’s fiancée Momiji and Albis’s overwhelming presence and strength.

She realizes that her feelings will not be reciprocated and experiences a deep heartbreak.

Phobio, having just failed to win Albis and having lost his own romantic hopes, finds himself in a similar emotional state.

The two quickly bond over their shared experience of unrequited love, and their relationship moves forward with surprising speed, hinting that they may become an important pair in the future.

Rigurd

Rigurd is one of Tempest’s senior goblin leaders and the first to greet Phobio when he arrives as an envoy.

Phobio injures him badly with a sudden punch, an act that instantly ruins his standing as a diplomat and triggers Milim’s intervention.

Later, through his interactions with Tempest and his reflection on the Charybdis incident, Phobio comes to understand how terrible his initial behavior was.

Rigurd’s mistreatment stands as a key example of how far he had to grow in terms of respect and diplomacy.

Phobio’s character arc is defined by humiliation, reflection, and growth.

He goes from an arrogant, narrow-minded enforcer to a more balanced, honorable commander who can admit mistakes and cooperate across national lines.

His early failures—assaulting Rigurd, being one-punched by Milim Nava, and becoming Charybdis’s vessel—are all severe but necessary lessons in humility.

These experiences push him to cultivate calm judgment, respect foreign powers like Tempest, and better align his actions with his loyalty to Karion and his responsibilities as a leader.

By the later volumes, his role as vice-commander of the Flying Beast Knight Order and his complex web of relationships show how far he has come.

He remains intense and passionate, but he is no longer just a “hot-headed brute”—he is a seasoned warrior, a dependable ally, and a surprisingly relatable figure dealing with pride, loyalty, and love.
