Does Rimuru Become a True Dragon in Season 4? Everything You Need to Know
If you’ve been following That Time I Got Reincarnated as a Slime for a while, you already know that Rimuru Tempest never stays at the same power level for long. Every season pushes him further—from a clever slime survivor to a full-blown Demon Lord. Now with Season 4 arriving, the hype is on a completely different level.
And let’s be honest—the real question everyone is asking isn’t if Rimuru will get stronger. It’s how far the anime is willing to go this time. Specifically: Are we finally getting True Dragon Rimuru?
As someone who genuinely enjoys the series (and has kept up with the source material), here’s the real deal—no fluff.
So… Does Rimuru Become a True Dragon?
Short answer: Yes—but timing is everything.
In the light novel, Rimuru reaches what fans often call his “final evolution” during the later stages of the Eastern Empire war arc. This transformation goes beyond anything we’ve seen in the anime so far. He essentially transcends his original species and becomes something entirely new.
But here’s the interesting part:
- Rimuru doesn’t become a traditional True Dragon
- Instead, he evolves into a unique existence that rivals them
- Yet, he is still recognized as the Fifth True Dragon
That’s a big deal in the TenSura world.
What Even Is a True Dragon?
To understand why this matters, you need context. True Dragons aren’t just strong—they’re basically forces of nature with consciousness.
| Name | Title | Role |
|---|---|---|
| Veldanava | Creator Dragon | Origin of the world |
| Velzard | Ice Dragon | Balance, control |
| Velgrynd | Scorch Dragon | Raw destructive force |
| Veldora | Storm Dragon | Chaos and energy |
Rimuru entering this category? That’s like going from top-tier player to game developer level power.
Rimuru vs. Eastern Empire: The Ultimate War Arc Summary and Analysis
What Changes After the Evolution?
Without spoiling too much detail, Rimuru’s transformation unlocks abilities that are honestly absurd in the best way possible.
- True Dragon-level energy output
- Access to abilities linked to both Veldora and Velgrynd
- Near-limitless regeneration and existence stability
- A refined, more mature human form
And visually? Expect subtle but noticeable changes—he looks older, more composed, and honestly more intimidating.
Will Season 4 Actually Show It?
Now here’s where things get interesting—and a bit speculative.
Season 4 isn’t a typical anime season. It’s planned as a long-form adaptation with a split cour format, which gives it room to cover major arcs from the light novel.
Likely progression:
- Early episodes → Political tension, Western Council, Rosso conflict
- Mid-season → Time-related chaos, Chronoa storyline
- Late season → Build-up to the Eastern Empire war
And that last part is where everything explodes, both literally and narratively.
My take: If the pacing stays consistent, Rimuru’s True Dragon evolution will most likely appear toward the end of Season 4, possibly as a climax or even a final arc payoff.
It’s too big of a moment to rush—and the studio knows it.
What Makes Season 4 Worth Watching Before That?
Even if you’re mainly waiting for the transformation, Season 4 has a lot going for it.
1. The Demoness Trio
- Testarossa
- Carrera
- Ultima
These aren’t just random characters—they’re Primordial Demons, and their dynamic with Rimuru adds both power and personality to the story.
2. Political Conflicts That Actually Matter
Unlike earlier arcs, the tension here isn’t just about battles—it’s about control, influence, and survival on a global scale.
Characters like Granbell Rosso bring a different kind of threat—less flashy, but just as dangerous.
3. Zegion Finally Gets His Moment
Zegion isn’t just that strong beetle guy. He’s one of Rimuru’s most powerful subordinates, and Season 4 should finally give him the spotlight he deserves.
Why This Evolution Feels Different
What makes Rimuru’s progression stand out is that it never feels random. Every power-up is tied to his relationships, his decisions, and his growth as a leader.
Becoming a True Dragon-level being isn’t just about strength—it’s the natural result of everything he’s built.
And honestly, that makes it way more satisfying than your typical anime power spike.
Final Thoughts
Season 4 of That Time I Got Reincarnated as a Slime is shaping up to be the most ambitious installment yet. Whether you’re here for the fights, the world-building, or Rimuru himself, there’s a lot to look forward to.
Will we see True Dragon Rimuru?
Almost certainly—just don’t expect it too early.
And when it finally happens, it won’t just be another upgrade. It’ll be the moment Rimuru fully steps into a league of his own.
