Aries is one of the Twelve Heavenly Stars of Conquest serving under Ruphas Mafahl in the series “A Wild Last Boss Appeared!”, a rare “Rainbow Sheep” monster granted the seat of Aries and infamous as a cute-looking but actually male “trap” follower whose true strength lies in terrifying percentage-damage skills rather than raw power.
Aries is a member of the Twelve Heavenly Stars of Conquest led by Ruphas Mafahl and holds the position corresponding to the constellation Aries.
He is a rare Rainbow Sheep monster who has learned human transformation and usually appears as a small, adorable girl, despite being unequivocally male.
His androgynous appearance is the result of a casual “character edit” decision made by Ruphas when she obtained the humanization arts as a Monster Tamer.
When she asked her companions how to design his humanoid form, Mizar (later one of the Seven Heroes) suggested making him a beautiful girl, then insisted that “traps are the trend,” which led directly to Aries’ current look.
Because of this, Aries is a victim of the eccentric whims of both Ruphas and the perverted master blacksmith Mizar, who has caused similar “incidents” with other characters as well.
Despite the comedic setup, Aries himself takes it in stride and simply continues to serve Ruphas with absolute devotion.
Among the Twelve Heavenly Stars, Aries has a gentle, mild personality and is one of the easier members to reason with.
However, his priorities are completely skewed toward his master: first Ruphas, second Ruphas, third and fourth also Ruphas, and only fifth “others,” most of whom are still his own group.
He is fundamentally a herd creature due to being a sheep-type monster.
That means he tends to follow the leader of the “flock” without question, and if the one at the front goes astray, he will naturally go astray as well.
Once Aries becomes attached to someone, his loyalty is extreme, and he will follow that person to the depths of hell if necessary.
This loyalty became the basis of his unshakable devotion to Ruphas, even after two hundred years.
Originally, Aries allowed himself to be manipulated by Mars and attacked the country of Svel, which was governed by the traitor Megrez.
Upon reuniting with Ruphas, however, he recovered his memories of his true role and called off the invasion, rejoining her as a follower.
Though feared by the people of Midgard as one of the Twelve Heavenly Stars of Conquest, Aries’ species, the Rainbow Sheep, is actually considered one of the weakest monster types.
Rainbow Sheep are normally hunted for their extremely valuable wool, which is so profitable it is said that owning one guarantees wealth for seven generations.
Aries was initially meant to be a “production-use” servant monster, raised specifically for harvesting rare wool rather than for combat.
Because of this, his combat ability is among the lowest within the Twelve Heavenly Stars if measured purely by stats and straightforward fighting power.
Aries is gentle, kind, and usually calm, especially compared to some of the more intense members of the Twelve Heavenly Stars.
He is approachable and able to hold normal conversations, which is not something that can be said for every powerful being in Ruphas’ entourage.
His loyalty borders on obsessive: Ruphas is always his highest priority.
If something benefits Ruphas, he will do it; if it harms her, he will oppose it, regardless of who stands in his way.
He places his “flock” above all else, with Ruphas at the head of that group.
This instinct explains why he could be misled when his “leader” position was confused, but also why he becomes immovably steadfast once his allegiance is clear.
Aries deeply resents those who betrayed Ruphas.
He especially dislikes the Seven Heroes who turned their backs on her, and he holds a grudge against them for harming the one who saved him.
He is fond of Ruphas and the other Twelve Heavenly Stars, regarding them as his precious companions.
Outside of that inner circle, his interest drops drastically, with most outsiders ranked far below his own group in importance.
Within the Twelve Heavenly Stars, he gets along particularly well with Aigokeros (Capricorn), Taurus (the Bull), and Karkinos (Cancer).
These are all comrades connected to Ruphas’ earlier adventurer days or those whose personalities align more closely with his own.
He is not on bad terms with the other Heavenly Stars, but there is some friction with Leon, the Leo.
Leon, the strongest beast among the Twelve, dislikes being considered on the same “tier” as Aries, who is biologically one of the weakest monsters, and feels insulted by the comparison.
Aries’ default human form is that of a cute, seemingly young girl with a soft and innocent aura.
Despite this girlish appearance, he is definitively male, a fact that often shocks those who discover it.
His design emphasizes the “trap” concept forced on him by Ruphas and Mizar, mixing feminine charm with his true male identity.
This mismatch is one of the character’s signature comedic and memorable traits in the series.
In his true monster form, Aries becomes a gigantic Rainbow Sheep.
When he unleashes his full monstrous nature, his body reaches around 100 meters in size, towering over the battlefield.
His wool burns with rainbow-colored flames when he fights seriously.
This creates a striking visual: a colossal, rainbow-blazing sheep charging and trampling enemies with overwhelming mass.
Aries’ base level is Lv 800, but his level can rise to Lv 1000 when he uses the power of Alkaid.
He belongs to the species Rainbow Sheep and possesses the Fire attribute.
His primary parameters are as follows:
HP: 75,000
SP: 7,600
STR (Attack Power): 4,100
DEX (Defense Power): 4,000
VIT (Vitality): 4,050
INT (Intelligence): 4,300
AGI (Agility): 4,170
MND (Mind/Spirit): 4,294
LUK (Luck): 4,180
Although these stats are high by normal standards, they are considered on the lower end among the Twelve Heavenly Stars.
Aries is less about overwhelming enemies with brute strength and more about using his unique, percentage-based skills to punch far above his weight.
Aries’ favorite people are Ruphas and his fellow members of the Twelve Heavenly Stars.
He dislikes the Seven Heroes, especially those who betrayed Ruphas.
In terms of food, he likes corn and grass.
Despite his power and humanoid form, his taste clearly reflects his original nature as a sheep monster.
Mesarthim
Mesarthim is a terrifying percentage-damage skill that continuously harms an opponent as long as Aries maintains physical contact.
The higher the target’s HP and Vitality, the more intense the damage becomes, up to a maximum of 99,999 damage.
Because it scales with the enemy’s own sturdiness, Mesarthim is particularly effective against “tanky” or high-HP opponents.
It is known by the fearsome nickname “Flame that Kills Gods,” since it allows Aries to burn down beings far tougher than himself.
Earthquake
Earthquake is a ground-attribute skill that allows Aries to deliberately trigger seismic shocks.
He can use it to shake the battlefield, topple enemies, and create chaos in the terrain.
This skill adds some area-control capability to his kit, complementing his otherwise close-range, contact-based fighting style.
While not his signature move, it is useful for disrupting formations and dealing with groups of enemies.
Hamal
Hamal is a limited skill available to Aries only when he is at Lv 1000.
When activated, it deals damage equal to 50% of the target’s maximum HP in a single blow.
Within the world’s game system, there is a damage cap of 99,999, so normally, no matter how high the enemy’s HP is—whether 200,000 or even tens of millions—the maximum displayed damage will be 99,999.
Because of this, Ruphas judges that, in pure practical terms, the skill Brachium is generally stronger under normal damage-cap conditions.
However, under certain special conditions where the damage cap can be bypassed, Hamal becomes absurdly powerful.
In that scenario, it can halve the target’s maximum HP outright and, with further combinations, potentially ignore the remaining HP entirely.
Due to its nature as a percentage-based attack, Hamal will always leave at least 1 HP remaining.
This means it does not by itself “one-shot” an enemy from full health, but it can put even the strongest foes on their knees in an instant.
The true terror of Hamal appears when it is combined with the power of Karkinos’ enhancement skill Altarf.
With Altarf doubling Hamal’s impact and if it lands cleanly, even Leon, the strongest of the Twelve Heavenly Stars, can be forced to his knees in a single strike.
Other Skills
Ruphas has granted Aries additional support and interference abilities beyond these three main skills.
However, as of the described material, only Mesarthim, Earthquake, and Hamal have been explicitly identified.
These hidden or lesser-known skills contribute to Aries’ utility in battle.
They help him disrupt opponents and enhance his allies even when he is not dealing the main damage himself.
In his human form, Aries specializes in fiery close-quarters combat.
He coats his fists in the flames of Mesarthim and pummels enemies with burning strikes that inflict continuous percentage damage.
He can also envelop his entire body in rainbow-colored flames and charge straight into enemies.
This “flame tackle” approach leverages both his mobility and his destructive contact-based skills.
When Aries fully unleashes his true monster nature, he transforms into a massive Rainbow Sheep over 100 meters tall.
In this form, he uses his enormous size to crush and overwhelm opponents physically.
As a giant monster, he can breathe fire from his mouth and ram enemies with his entire flaming body.
Just like in his human form, he shrouds himself in rainbow flames and turns his mass into a living weapon.
Aries is not a pure frontline bruiser despite his size; he is a specialist in percentage-based attrition and sudden, high-impact bursts like Hamal.
His role in the Twelve Heavenly Stars is to threaten even top-tier enemies through clever use of scaling damage, rather than out-muscling them directly.
Before meeting Ruphas, Aries lived as a weak Rainbow Sheep at the bottom of the food chain.
His species was coveted for its precious wool, which was traded at high prices and believed to bring wealth for seven generations to those who possessed it.
Because Rainbow Sheep are among the weakest monster types, Aries spent his early life as prey.
He survived by constantly running away, living in fear and knowing nothing but being hunted.
Everything changed when he encountered Ruphas, before she had fully become known as the Conquering Overlord.
She took him in, raised him as a servant monster, and granted him the strength he has today.
Through Ruphas’ guidance and the growth he underwent by her side, Aries went from a helpless victim to one of the feared Twelve Heavenly Stars of Conquest.
He came to worship her as his savior, not just his master.
Aries is profoundly grateful to Ruphas for giving meaning to a life that had been nothing but escaping danger.
That gratitude did not fade even after two hundred years passed, remaining the core of his unwavering loyalty and emotional support.
The story of Aries’ first meeting with Ruphas and how his life was transformed is depicted in the original work.
Readers are encouraged to check the source material to fully experience this emotional episode and see how their bond was forged.
Aries being a “trap” is entirely the result of out-of-universe-like character customization decisions within the story’s game-style mechanics.
Ruphas and Mizar’s choice illustrates both the lighthearted humor of the series and how casually powerful beings can alter someone’s life.
Despite being feared as a high-ranking boss-class monster, Aries’ essence as a sheep never fully disappears.
His love of grass and corn, his herd mentality, and his gentle core all hint at the timid creature he once was.
His combat design is built around “giant-killing” mechanics, such as Mesarthim and Hamal.
This makes him extremely dangerous to bosses and powerful enemies, even though he is not the raw strongest among the Twelve Heavenly Stars.
His relationship with Leon provides comic friction within the group.
The proud, strongest beast finds it offensive to be grouped alongside a “wool monster,” while Aries himself mostly just wants to follow Ruphas and support his companions.
