Is Rimuru Stronger Than Guy Crimson After Season 4? Tensura Power Levels Explained
If there is one Tensura power-scaling debate that never seems to die, it is Rimuru Tempest vs. Guy Crimson.
And honestly, I understand why.
Rimuru has gone from an ordinary salaryman reincarnated as a slime into one of the most ridiculous beings in the entire That Time I Got Reincarnated as a Slime universe. Every major arc seems to give him another evolution, another Ultimate Skill, another absurd ability, or another ridiculously strong subordinate.
So after Season 4, it is very tempting to look at Rimuru’s current arsenal and think: surely he has finally surpassed Guy Crimson.
I don’t think he has.
At least, not yet.
If we’re talking specifically about where the anime’s Season 4 storyline leaves Rimuru, I would still put Guy above him in a direct fight. Rimuru is terrifying at this point, and Tempest has arguably become the most dangerous political and military force in the world. But Guy is operating on a completely different level when it comes to experience, combat ability, and, most importantly, dealing with the mechanics of the world’s highest-level battles.
And that distinction matters a lot in Tensura.
My Verdict: Guy Still Beats Post-Season 4 Rimuru
Let’s get the simple answer out of the way first.
| Character | Post-Season 4 Standing | Biggest Advantage |
|---|---|---|
| Rimuru Tempest | Extremely High | Versatility, analysis, Ultimate Skills |
| Guy Crimson | Absolute Top Tier | Combat experience and Time Stop mastery |
| Milim Nava | Absolute Top Tier | Overwhelming destructive power |
| True Dragons | Cosmic Tier | Ridiculous existence and elemental power |
Rimuru is absolutely approaching the highest level of the Tensura universe, but I don’t believe the Season 4 version has completely crossed that final threshold.
The important thing is that having more abilities doesn’t automatically mean winning a fight.
That’s something Tensura’s power system makes surprisingly clear.
How Strong Is Rimuru After Season 4?
By this point, Rimuru is no longer simply a powerful Demon Lord.
He is an Awakened Demon Lord with an enormous amount of energy, incredible regeneration, ridiculous defensive capabilities, and some of the most useful Ultimate Skills in the series.
Raphael, in particular, is one of the biggest reasons Rimuru can compete with monsters that have existed for thousands of years.
Raphael allows Rimuru to process information at an absurd speed, analyze abilities, optimize skills, and find solutions to problems that would be completely impossible for a normal character.
Then there is Beelzebuth, which gives Rimuru terrifying offensive and defensive options through absorption and consumption.
This combination makes Rimuru incredibly difficult to kill.
And that’s before considering the rest of Tempest.
Diablo alone is a nightmare for most opponents. Then you add the other Primordial Demons such as Testarossa, Ultima, and Carrera, and suddenly Rimuru isn’t just personally powerful — he has an army capable of making even ancient supernatural beings take Tempest seriously.
This is why I think it is easy to overestimate Rimuru at this particular point.
His overall influence has become enormous, but influence and individual combat superiority aren’t exactly the same thing.
Why Guy Crimson Is Still a Nightmare Matchup
Guy Crimson is different from Rimuru in one crucial way.
Guy didn’t suddenly become powerful after a few years of growth.
He has been sitting near the top of the Tensura power hierarchy for an incredibly long time.
He is the Primordial Red, one of the oldest and most dangerous demons in existence, and his history includes encounters with beings that Rimuru has only recently begun approaching in terms of power.
That’s why I wouldn’t judge Guy simply by looking at destructive power.
The real problem is what Guy can do in an actual fight.
1. The Suspended World Is the Biggest Problem
For me, this is the single biggest reason I would still favor Guy against the Season 4 version of Rimuru.
The Suspended World, essentially the series’ terrifying form of stopped time, changes the rules of combat completely.
Imagine having an opponent who can stop time and continue functioning while you can’t.
It doesn’t matter how fast your reactions normally are.
It doesn’t matter how powerful your attacks are.
It doesn’t matter how many calculations your Ultimate Skill can perform.
If you cannot properly perceive or interact with reality during stopped time, your opponent has an enormous advantage.
This is why normal power scaling doesn’t work particularly well when discussing Guy.
You can give Rimuru incredible destructive power, regeneration, barriers, absorption, and analytical abilities, but if he cannot properly respond to Guy’s highest-level temporal techniques, those abilities may never get the chance to matter.
2. Guy’s Combat Experience Is Almost Unfair
Another reason I favor Guy is experience.
Rimuru has learned unbelievably quickly, but his existence in the Tensura world is still relatively short compared with Guy’s history.
And there is a difference between being intelligent and having thousands of years of combat experience.
Raphael can calculate.
Raphael can analyze.
Raphael can optimize.
But Guy has actually fought monsters and supernatural beings at the highest level for an enormous amount of time.
That battle instinct matters.
It’s one of those things that doesn’t always look impressive on a character sheet, but becomes incredibly important when two absurdly powerful characters actually fight.
3. Lucifer Makes Guy Even More Dangerous
Guy’s Ultimate Skill Lucifer, Lord of Pride, is another major reason this matchup is so difficult for Rimuru.
Guy isn’t simply a brute-force character.
His ability to analyze and reproduce techniques means that throwing increasingly complicated abilities at him isn’t necessarily the solution.
That’s what makes the fight so interesting.
Rimuru’s greatest strength is arguably his adaptability.
Unfortunately for him, Guy is also an adaptability monster.
So this isn’t a situation where Rimuru can simply reveal one unexpected ability and immediately win.
Guy has the experience and skill set necessary to understand what he’s fighting.
When Does Rimuru Actually Surpass Guy?
This is where the conversation gets much more interesting.
If you’re willing to go beyond the anime and into the Tensura light novel, Rimuru’s development eventually reaches a completely different stage.
Later events introduce enormous changes to Rimuru’s existence, his abilities, and his relationship with Ciel.
The evolution from Raphael toward Manas: Ciel is especially important.
At that point, Rimuru’s analytical capabilities become something far beyond what we saw earlier in the story. His connection with Ultimate Skills and his ability to manipulate increasingly ridiculous levels of power push him toward the absolute ceiling of the setting.
Then comes Void God Azathoth, which takes Rimuru’s arsenal into territory that is difficult to compare with his Season 4 self.
But even here, I wouldn’t say the answer is simply:
“Rimuru gets a stronger skill, therefore Guy loses.”
That’s too simplistic.
The real turning point is Rimuru eventually gaining the ability to properly function within the Suspended World.
Once Rimuru can actually participate in battles where time itself has effectively stopped, Guy loses one of his biggest advantages.
And that’s when the matchup changes dramatically.
The Difference Between Anime Rimuru and Late-Story Rimuru
This is probably the most important thing for anime-only fans to remember.
Season 4 Rimuru and late-story Rimuru are practically two different power-scaling conversations.
Season 4 Rimuru is already ridiculously powerful.
Late-story Rimuru becomes something much closer to the ultimate expression of what the series’ power system allows.
That’s why saying “Rimuru is stronger than Guy” without mentioning the timeline is misleading.
If we’re talking about post-Season 4 Rimuru, I still give the fight to Guy.
If we’re talking about Rimuru much later in the light novel, the answer changes substantially.
My Personal Ranking
If I had to rank the characters around this part of the story based on a mixture of raw power, abilities, experience, and actual combat effectiveness, I’d put them roughly like this:
- Guy Crimson
- Other absolute top-tier monsters
- Rimuru Tempest
- The strongest Demon Lords and Primordial-level combatants
- Other high-end awakened beings
Obviously, Tensura’s power system is too complicated for a perfect numbered list, and matchups matter enormously. Still, this is how I personally see the post-Season 4 situation.

Final Thoughts: Rimuru Isn’t There Yet — But He’s Getting Close
This is actually what makes the Rimuru vs Guy Crimson debate so fun.
Rimuru doesn’t need to already be stronger than Guy for the matchup to be exciting.
The whole appeal of Rimuru’s character is watching him continuously break through limits that previously seemed impossible.
Guy represents the old guard — an ancient monster who has spent thousands of years sitting near the summit of the world’s power structure.
Rimuru represents something completely different.
He is the absurdly fast-growing newcomer who keeps evolving beyond everyone’s expectations.
So, is Rimuru stronger than Guy Crimson after Season 4?
My answer is no.
Guy still has the more complete package for a direct battle, especially because of his experience and mastery of the highest-level mechanics such as the Suspended World.
But I also wouldn’t bet against Rimuru forever.
Because if there’s one thing That Time I Got Reincarnated as a Slime has taught us, it’s that whenever Rimuru reaches what looks like his limit, that limit usually doesn’t survive for very long.
And that’s exactly why I’m much more interested in where the anime takes him next than in pretending the current power hierarchy is permanent.
