Mariabell Rosso vs. Clayman: Who is the Strongest in Tensei Slime?
If you’ve watched or read That Time I Got Reincarnated as a Slime, you already know that power scaling in this series is absolutely wild. In Tensura, strength isn’t just about who punches harder. It’s about Unique Skills, soul manipulation, Ultimate Skills, and psychological warfare. That’s exactly why the debate between Mariabell Rosso vs. Clayman is so interesting and still discussed among anime fans.
On paper, Clayman looks like the bigger threat. He’s a Demon Lord Seed, he undergoes an awakening, and he makes a dramatic appearance at Walpurgis. But if you really analyze their abilities and influence, Mariabell might actually be the more dangerous antagonist overall.
Mariabell Rosso – The Most Dangerous Human in Tensura?
Mariabell Rosso isn’t flashy. She doesn’t scream about evolution or becoming a True Demon Lord. Instead, she controls the world quietly from the shadows, which in Tensura is often far more terrifying than brute strength.
- Unique Skill: Greed (Sins Series) – This is not ordinary mind control. Greed amplifies desire, ambition, and inner corruption. She doesn’t force obedience; she makes her targets want to follow her. That distinction is what makes the ability so dangerous. Unlike Puppeteer, which overrides, Greed manipulates the foundation of a person’s soul.
- Economic Domination – Mariabell essentially controls the Western Nations through financial systems and political leverage. In the world of Tensura, economics equals power. Armies move because of funding. Alliances shift because of trade. She weaponized currency.
- Influence Over Granbell – The fact that even the legendary Hero was not entirely outside her influence speaks volumes about her reach and strategic brilliance.
What makes Mariabell truly frightening is that she doesn’t need to fight directly. If you lack an Ultimate Skill protecting your soul, you are vulnerable. And in Tensura, most beings are driven by ambition, pride, or desire. That means most beings are potential targets.
Clayman – The Dramatic Marionette Master
Clayman represents the more classic anime antagonist archetype. A member of the Moderate Harlequin Alliance, a Demon Lord Seed, and a self-proclaimed mastermind pulling strings from the shadows.
- Unique Skill: Puppeteer – Clayman can directly manipulate the bodies and souls of those weaker than him. It’s efficient and brutal, but it has clearer limitations compared to a Sins-series skill.
- Leyline Communication – His intelligence network allowed him to monitor events across vast distances, making him a competent strategist.
- Forced Awakening – During Walpurgis, Clayman’s incomplete awakening dramatically increased his magicule count and physical capabilities. In this state, he surpassed lower-tier Demon Lords like Frey and Carrion in raw output.
However, Clayman’s greatest weakness was always his arrogance. He relied heavily on schemes and external tools instead of strengthening his own soul. In Tensura, that flaw is fatal.
Direct Comparison: Skill vs. Raw Power
| Category | Mariabell Rosso | Clayman |
|---|---|---|
| Raw Physical Power | Low (Human Body) | High (Awakened Form) |
| Unique Skill Tier | Sins Series – Top Tier | Strong but Inferior |
| Strategic Intelligence | Extremely High | High but Arrogant |
| Political Influence | Massive | Moderate |
| Soul-Based Hax | Very High | Medium |
Scenario 1: Political or Strategic Conflict
In a war of influence, Mariabell wins decisively. Clayman builds puppet states over time, but Mariabell controls financial systems and leadership structures. She operates on a systemic level. While Clayman manipulates individuals, Mariabell manipulates civilizations.
Scenario 2: Base Form 1v1 Battle
This is where things become nuanced. If Mariabell activates Greed first and amplifies Clayman’s already overwhelming desire for power, she could potentially hijack him. Since Greed belongs to the Sins Series, it generally outranks standard Unique Skills like Puppeteer in hierarchy and conceptual authority.
However, if Clayman resists long enough to apply direct force, Mariabell’s physical fragility becomes a serious liability.

Scenario 3: Awakened Clayman vs. Mariabell
In his awakened state, Clayman has a significant advantage in raw combat. His magicule reserves increase dramatically, and his durability rises to Demon Lord levels. If he blitzes her before Greed takes effect, he likely wins through sheer physical superiority.
Mariabell’s greatest weakness remains her human vessel. Without powerful defensive artifacts or preparation, she risks being overwhelmed in direct combat.
The Bigger Lesson: Why Both Failed
Ultimately, both Mariabell and Clayman fell for the same reason: they underestimated Ultimate Skills. In Tensura, Ultimate Skills represent absolute authority over a concept and provide near-immunity to mental interference.
Mariabell believed Greed could dominate anyone, including Rimuru. Clayman believed his awakening placed him among true Demon Lords. Both miscalculated the evolutionary gap between themselves and Rimuru Tempest.
They weren’t weak. They were simply operating on the wrong level of the power hierarchy.
Final Verdict: Who Is Truly Stronger?
- Skill-Wise: Mariabell Rosso. Greed is conceptually superior and far more dangerous in long-term scenarios.
- Combat-Wise: Awakened Clayman. His physical stats and magicule reserves give him the edge in a direct confrontation.
- Overall Threat Level: Mariabell Rosso. Her ability to manipulate economies, politics, and human desire makes her a systemic threat rather than just a battlefield opponent.
In Tensura, true power isn’t just about magicules or brute strength. It’s about control over the soul and authority over concepts. And in that regard, Mariabell understood the game on a deeper level than Clayman ever did.
