Tensura Ultimate Skills Ranked: Strongest Abilities Explained

If you’ve been around the Tensura fandom for even a short time, you already know the power system in That Time I Got Reincarnated as a Slime is completely unhinged in the best way possible. Ultimate Skills aren’t just “strong abilities”—they are conceptual authorities that rewrite reality itself.

As a fan who has followed the series discussions across Reddit, YouTube breakdowns, and light novel debates, I’ve noticed one thing: everyone has a different “true” top tier list.

And honestly, that chaos is part of the appeal. Still, some skills consistently stand out as absurdly broken no matter how you look at them.

This is a fan-based ranking of the strongest Ultimate Skills in Tensura, focusing on versatility, narrative impact, and sheer broken mechanics rather than pure favoritism.

Top 10 Strongest Ultimate Skills in Tensura

10. Beelzebuth (Lord of Gluttony) – Rimuru Tempest

Beelzebuth is one of the most iconic early Ultimate Skills because it turns consumption into an absolute weapon. It allows Rimuru to absorb almost anything—attacks, matter, energy, and even skills—without limitation. The stored targets are analyzed and processed inside an isolated space, making it both offense and utility.

It also enables the “Food Chain” system, distributing power between Rimuru and his subordinates, which makes it foundational for his entire growth.

9. Uriel (Lord of Vows) – Rimuru Tempest

Uriel is pure defense and spatial control perfected. Its Universal Barrier provides near-impenetrable protection, while its spatial manipulation allows instant movement across space and dimensions.

What makes it terrifying is how absolute its defensive logic is—most attacks simply never reach Rimuru in the first place.

8. Faust (Lord of Investigation) – Veldora Tempest

Faust is chaotic in the best possible way. It manipulates probability itself, allowing Veldora to tilt outcomes in his favor regardless of logic.

Combined with instant analysis abilities, it turns him into a combatant who learns and wins faster than the opponent can adapt.

7. Michael (Lord of Justice) – Rudra / Feldway

Michael represents authority and domination at a conceptual level. Its Castle Guard ability becomes stronger based on loyalty and belief, making it nearly unbreakable under the right conditions.

It also includes mind control and large-scale domination effects, making it one of the most oppressive Ultimate Skills in the series.

6. Raguel (Lord of Charity) – Velgrynd

Raguel is pure destructive energy disguised under a calm name. It accelerates heat, motion, and energy at a fundamental level, causing targets to collapse from within.

It ignores conventional defense because it does not attack externally—it destabilizes existence internally.

5. Sariel (Lord of Hope) – Chloe Aubert

Sariel introduces high-level time manipulation and conceptual slicing. It allows Chloe to cut through anything, including abstract defenses and spatial barriers.

Its partial time control makes it extremely dangerous in high-speed battles where milliseconds decide outcomes.

4. Nordens (Lord of the Abyss) – Guy Crimson

Nordens is one of the most unfair combat skills in the series. It allows Guy to analyze, copy, and replicate abilities after seeing them once.

This effectively removes any uniqueness from enemy abilities during combat, making adaptation Guy’s greatest weapon.

3. Yog-Sothoth (God of Space-Time) – Chloe Aubert

This evolved version of Sariel takes time manipulation to an entirely new level. Yog-Sothoth can freeze the entire universe, granting absolute control over frozen time.

Within this state, Chloe can move freely while all others are completely immobilized unless they possess similar high-tier resistance abilities.

2. Cthugha (Lord of Flame) – Velgrynd (Evolved)

Cthugha evolves Raguel into a multi-dimensional combat system. It enhances perception speed, grants dimensional travel, and allows attacks across multiple layers of existence.

It essentially turns Velgrynd into an unstoppable force that cannot be hidden from or escaped.

1. Void God Azathoth – Rimuru Tempest

Azathoth sits at the absolute top due to its control over void energy and reality-level authority. It allows Rimuru to manipulate existence itself through Turn Nullity, a primordial force capable of creation and destruction.

Combined with an infinite storage dimension and time-space dominance, Azathoth represents full conceptual control over the battlefield.

At this level, Rimuru no longer “fights” in the traditional sense—he defines the rules of the fight itself.

Final Thoughts

The fascinating part about Tensura is that power scaling is never truly stable. What feels absolute today may be outdated tomorrow due to new evolutions and narrative expansions.

Ultimate Skills are not just abilities—they are narrative tools that determine who gets to bend reality in their favor. And in most cases, Rimuru and his closest allies sit at the center of that shifting hierarchy.
