Top 10 Strongest Characters in Tensura Light Novel (EOS Ranked)
If there’s one thing that separates That Time I Got Reincarnated as a Slime from most modern fantasy series, it’s the absolutely insane power scaling. What started as a fun isekai about a slime building a peaceful monster nation slowly transformed into a cosmic-level war involving gods, dragons, time manipulation, and reality-breaking abilities.
As someone who has followed the light novel for years, I honestly think Tensura has one of the most entertaining “late-game evolutions” in anime and LN history. Fuse somehow managed to take characters who were already absurdly strong and push them into multiversal territory without making the story completely collapse under its own weight.
By the end of the series, fights are no longer about simple strength. Battles revolve around Ultimate Skills, conceptual abilities, suspended time combat, dimensional control, and infinite energy systems. Some characters can erase worlds casually, while others can manipulate probability or exist outside the normal flow of time itself.
Here’s my personal EOS (End of Series) ranking of the strongest Tensura characters based on light novel feats, scaling discussions, and overall combat portrayal.
Top 10 Strongest Tensura Characters Ranked
| Rank | Character | Main Power |
|---|---|---|
| 10 | Michael | Absolute defense and skill domination |
| 9 | Feldway | Primordial angel with multiversal tactics |
| 8 | Velgrynd | Dimensional acceleration and flame power |
| 7 | Velzard | Absolute freezing and temporal control |
| 6 | Guy Crimson | Infinite combat adaptation |
| 5 | Veldora Tempest | Probability manipulation |
| 4 | Chloe Aubert | Space-time domination |
| 3 | Milim Nava | Infinite rage-based energy growth |
| 2 | Ivaraj | Pure destruction beyond the world |
| 1 | Rimuru Tempest | Reality-defying creator entity |
10. Michael — The Ultimate Defensive Monster
Michael was terrifying because he wasn’t just powerful — he was unfair. Once the Virtue Skill evolved into a Manas, he became one of the biggest threats in the entire late story.
His signature ability, Castle Guard, is still one of the craziest defensive skills in Tensura. As long as people remain loyal to him, the barrier is essentially impossible to break. Add in Time Stop abilities and massive dragon-level energy reserves, and you get a character who can dominate almost anyone below the absolute top tier.
What keeps him lower on this list is creativity. Compared to monsters like Rimuru or Guy Crimson, Michael feels more like a perfect weapon than an unpredictable fighter.
9. Feldway — The Most Dangerous Strategist
Feldway gives off final-boss energy from the moment he appears. As the first angel created by Veldanava, his existence alone already places him near the top of the verse.
What makes Feldway terrifying isn’t raw destruction — it’s efficiency. He combines ancient combat experience, multidimensional movement, top-tier swordsmanship, and strategic intelligence at a level very few characters can match.
Once he obtains Michael’s abilities and a True Dragon vessel, Feldway becomes capable of fighting across dimensions while maintaining near-perfect defenses. Honestly, he feels like the “professional killer” of the Tensura universe.
8. Velgrynd — Speed Taken to God Tier
Among the True Dragons, Velgrynd might be the hardest to actually pin down in combat.
Her evolved powers allow her to move through dimensions almost instantly, and her control over acceleration makes distance practically meaningless. The scary part is that she doesn’t even need to physically reach you to attack.
I always liked how Fuse handled Velgrynd because she feels elegant rather than brutish. While some characters rely on overwhelming force, she fights with precision and absurd speed.
Her dimensional travel abilities alone make her one of the strongest entities in the series.
7. Velzard — The Queen of Absolute Control
Velzard is one of those characters that feels unbeatable simply because she controls the pace of battle completely.
Her freezing abilities aren’t just elemental attacks — they affect motion, energy, and even the flow of time itself. That’s what makes her terrifying. Against most enemies, once Velzard establishes control, the fight is basically over.
She’s also one of the few characters who consistently kept Veldora under control for centuries, which says everything you need to know about her combat level.
6. Guy Crimson — The Definition of Experience
There’s a reason Guy Crimson still feels dangerous even among the EOS monsters.
Unlike characters who rely mainly on raw power, Guy wins through adaptation, intelligence, and terrifying combat instincts. His ability to copy and analyze skills makes him nearly impossible to surprise in battle.
What I personally love about Guy is that he always feels calm. Even during world-ending conflicts, he acts like someone who has already seen everything before.
His fights with Velzard and True Dragons prove he belongs among the strongest beings ever introduced in Tensura.
5. Veldora Tempest — Chaos in Dragon Form
Veldora might honestly have the biggest glow-up in the entire series.
At first, he was basically a walking natural disaster with no discipline. But after spending time with Rimuru and absorbing human culture (especially manga), he became weirdly tactical while still keeping his chaotic personality.
His probability manipulation ability is ridiculously broken. In practice, it means reality itself bends in his favor.
And let’s be honest — “Veldora Killing Arts” is still one of the funniest and coolest concepts Fuse ever introduced.
4. Chloe Aubert — The Strongest Hero
Chloe is one of the most complicated characters in Tensura lore, but also one of the most overpowered.
Her mastery over time and space basically allows her to rewrite battles before they even happen. Fighting someone who can manipulate timelines is already unfair — fighting someone who can perfect swordsmanship on top of that becomes almost impossible.
What makes Chloe special is that she doesn’t feel like a pure mage or a pure warrior. She’s both simultaneously.
At EOS, very few characters can survive a serious fight against her.
3. Milim Nava — Infinite Destruction
Milim is pure chaos wrapped inside one of the cutest character designs in anime.
But behind the playful personality is probably the most naturally destructive fighter in the series. Her energy literally continues increasing the longer she fights, which makes her terrifying in prolonged battles.
Once Milim enters Stampede mode, things become catastrophic fast. Entire landscapes disappear, defenses collapse, and most characters simply cannot endure her overwhelming force.
She feels like a living apocalypse.
2. Ivaraj — The Monster Beyond Logic
Ivaraj barely even feels like a normal Tensura character.
This thing represents destruction in its purest form — an entity from outside the world itself. Even Veldanava struggled to truly eliminate it permanently.
What makes Ivaraj so scary is the lack of limitations. Its existence naturally corrupts and destabilizes reality around it. By the final arcs, it evolves into something closer to a cosmic disaster than a living creature.
In another series, Ivaraj would easily be the final unbeatable god-tier enemy.
1. Rimuru Tempest — The Absolute Peak of Tensura
At EOS, Rimuru completely transcends the normal power system.
With Ciel constantly optimizing every ability and Azathoth providing virtually infinite energy, Rimuru becomes less like a slime and more like a creator deity. He can manipulate concepts, recreate worlds, absorb attacks into Imaginary Space, and exist beyond ordinary dimensional limits.
The craziest part is how effortless it eventually feels for him.
Early Tensura Rimuru was clever and cautious. EOS Rimuru feels like a being operating on an entirely different layer of existence compared to everyone else.
And honestly? After everything he went through across the light novel, it feels earned.
Final Thoughts
One thing I genuinely appreciate about Tensura is that power scaling never feels completely random. Every evolution usually connects back to the world’s lore, Ultimate Skills, or Veldanava’s original system.
Even among insanely overpowered characters, each fighter has a unique identity:
- Rimuru represents evolution and adaptation
- Milim embodies destruction
- Chloe controls time itself
- Guy Crimson symbolizes experience and mastery
- Veldora thrives on unpredictability
That variety is what keeps Tensura entertaining even after the story reaches universe-level stakes.
For me personally, EOS That Time I Got Reincarnated as a Slime stands alongside the craziest fantasy scaling series ever written.
