Lymur is an "archetype" of Rimuru Tempest—the Great Demon Lord, Chaos Creator, Allfather, and Supreme Ruler of Tempest.
Lymur was originally made with a separate soul and ego and imbued with a personality derived from Rimuru's own but with pretty major changes—making him more calculative, assertive, and confident in general (although he still has to properly develop his personality). His purpose was to be sent to another world, featuring what could've transpired if Rimuru had an abundance of strength but a lack of versatility—namely, through the absence of an assistant model like the Great Sage or a Manas. Furthermore, Rimuru essentially rendered Lymur incapable of most magic that can be learnt—including healing and resurrection magic.

Species
The Archetypes are an artificial and anthropomorphic species that are fully independent facets of a sufficiently powerful being. The first Archetype, Lymur, was created by Rimuru Tempest. He was derived from Rimuru's own cells but manifested with actual flesh and blood. Archetypes are chaos-aligned and as divine entities, they possess immortal material bodies that will never age. Their strength is mostly dependent on their "parent" and they are similar to True Dragons in the way that they cannot evolve, but only improve.

Appearance
Lymur is a tall, lean, and muscular man who appears to be at least in his late teens, or at most in his early twenties. His physique resembles that of Rimuru's human form, but with references to Veldora Tempest. The result is a balanced build that is neither overly bulky nor delicate. His face still has the androgynous beauty of Rimuru, with sharp yet refined features that make it difficult to assign a clear gender impression. His skin is pale and flawlessly smooth, lacking scars or blemishes. His hair is a shade of royal blue that falls loosely around his face in soft layers. His eyes, meanwhile, are a deep blood red.

Personality
Lymur is designed as a refined balance between Rimuru's human and monstrous aspects, developed further by his own distinct traits. He is confident, sharp-tongued, and consistently composed, often with a casual — even lazy — demeanor despite his overwhelming power. This relaxed attitude may appear reckless, but it hides a high level of awareness. Rather than relying on exhaustive calculation like his creator, Lymur trusts his instincts, making rapid decisions and adapting to changing situations.
He inherits Rimuru's eccentric humor, frequently teasing others and treating tense situations with a degree of irreverence. This humor is not always meant to manipulate or deceive; more often, it reflects his genuine personality and the strange boredom that can come from possessing overwhelming strength. Since he rarely ever feels threatened, Lymur treats most circumstances with a calm, slightly playful disposition.
However, once engaged in combat, Lymur's behavior and demeanor take a complete turn. He becomes intensely and aggressively decisive, demonstrating virtually instinctive mastery in battle. His fighting style is centered around constant pressure, adaptability, and technical precision, allowing him to overwhelm opponents through skill and timing alone—even without the aid of his advanced analytical abilities.
Lymur's defining trait is his absolute confidence. Unlike Rimuru, this self-assurance is entirely self-developed and is so complete that it borders at times on irrationality. While this belief in his inevitable victory can lead to underestimating threats (a total contrast to his creator's earlier worldview), it also serves as a source of strength. As a spiritual lifeform, his power is closely tied to his will, meaning that doubt weakens him while conviction amplifies his abilities.
His outlook on the world is pragmatic, particularly regarding life and death. Though he values those close to him and encourages their growth, he does not believe in saving everyone. He accepts death as inevitable, choosing to honor loss through continued action rather than prolonged grief. While capable of empathy, he still prioritizes being emotionally steady in the face of tragedy, treating it as something to endure rather than something that dictates his future. Whether this "acceptance" is a form of self-developed mindset or an artificially imbued trait by God is unclear.
Lymur is not inherently cruel, but he is willing to employ violence without hesitation when necessary. To him, brutality is a tool rather than a vice, and his moral decisions are guided by practicality rather than rigid ideals. This balance further makes his behavior difficult to predict.
As an Archetype, his existence fundamentally shapes his identity. Though he originates from God, he dislikes the idea of being merely an extension, instead subconsciously pursuing a life defined by his own choices. This fuels a drive for self-definition, pushing Lymur to test his limits and carve out an identity that belongs entirely to him.
Despite his immense power, Lymur often experiences a sense of aimlessness. When challenges fail to stimulate him or he is frequently haunted by dreams about "the person with golden eyes," the world can feel hollow. Rather than succumbing to apathy, however, he uses this emptiness as motivation to continually seek new challenges and experiences to give his existence meaning.
Ultimately, as an Archetype, Lymur represents a version of Rimuru defined not by calculation and protection, but by instinct, overwhelming strength, and a relentless pursuit of self-definition.

Abilities
Being a "facet" of the Supreme Deity Rimuru Tempest as well as being the first Archetype, Lymur is a genuine deity. He was designed specifically to be a far more combat-oriented existence than Rimuru.
He possesses extraordinary talent in swordsmanship and hand-to-hand combat through ingrained muscle memory, capable of adapting instantly to changing battlefield conditions. His fighting style is characterized by speed, aggressive precision, and relentless pressure to overwhelm opponents. Unlike Rimuru, Lymur cannot rely on an arsenal of versatile magic. He is largely incapable of learning almost all forms of magic, including healing or resurrection spells. To compensate, Lymur possesses immense computational ability and combat intuition.
The central idea around which his power level was built was "sufficient strength to survice, sufficient weakness to fail."
1. Intrinsic Skills
1.1 Ruler's Ambition: Haki that passively suppresses the abilities of those within its range, reducing the effectiveness of enemies' skills and magic by a proportional margin. This aura also instills an overwhelming sense of awe and obedience in weaker beings, compelling them to submit to the user's will. Conversely, it can inspire great fear upon lesser beings.
1.2 Ruler's Authority: Seizes and manipulates spatial coordinates rather than physical objects. By grasping the location a target occupies, the user can drag that coordinate through space, forcing anything bound to it to move accordingly. Since the skill occurs at the level of spatial designation rather than physical interaction, targets are moved without inertia, resistance, or transitional motion.
1.3 Invariant: It is a perfect internal equilibrium regardless of external influence. Attempts to disrupt the user's mind, corrupt their consciousness, distort their perception, or overload their awareness are automatically neutralized as their existence continually reasserts its original state. This allows the user to process vast amounts of information and endure extreme conditions without degradation of cognition or identity.
2. Unique Skill
2.1 Mobius
2.1.a Theosophy: Grants the user an extraordinary level of awareness that allows them to instantly sense and examine all forms of stimuli within the range of their perception. In addition, it provides the user an understanding of whatever they observe directly. Along with this feature is the ability to perceive time in a distinctively accelerated pace relative to the external world.
2.1.b Calculation Domain: An analytical ability that allows the user to analyze and identity objects and phenomena at its fundamental level. It enables the user to understand, track, and counter magic, skills, and phenomena. While some methods can obscure information, true concealment is nearly impossible, as even the lack of data itself will be noticeable.
2.1.c Incision: Allows the manifestation of one-dimensional lines with absolute zero thickness. Because the lines possess length but no width or depth, they therefore occupy no volume and possess infinite sharpness. This allows the Incision lines to pass between the molecular bonds of any material, severing objects at the atomic level without meeting physical resistance.
2.1.d True Sphere: It allows the user to manifest a mathematically perfect sphere into reality—an object with infinite contact points, rendering it absolutely untouchable. Since a perfect sphere has no imperfections and distributes force across an infinite number of points, it creates infinite pressure, instantly annihilating anything it comes into contact with.
2.2 Collapse
2.2.a Void Space: A personal storage dimension connected to the Void. Objects placed inside are preserved in a suspended state where time does not meaningfully progress. Lymur can freely store or retrieve items within this space as long as they fall within the capacity of the skill.
2.2.b Confluence: Forcibly compresses or decompresses a designated region of space. Everything within that area is violently dragged toward the collapsing point as space itself contracts, crushing matter and energy under extreme pressure. Alternatively, matter and energy alike are explosively expunged from a single point to the degree of disintegration.
3. Resistances
3.1 Abnormal Condition Resistance
3.2 Magical Attack Resistance
3.3 Natural Effects Resistance
3.4 Physical Attack Resistance
3.5 Spiritual Attack Nullification
