Ever found yourself wondering about the age of Rimuru Tempest, the unassuming yet incredibly powerful slime, specifically within the action-packed universe of Dragon Ball Z? If so, you're not alone in picturing such an epic crossover! However, let's clear the air right from the start: Rimuru Tempest does not exist in the Dragon Ball Z universe, nor does any official storyline place him there. He hails exclusively from his own fantastical world, That Time I Got Reincarnated as a Slime (TenSura).
This distinction is crucial because comparing characters across vastly different fictional universes, each with its own unique rules of power, aging, and existence, often leads to fascinating but ultimately speculative discussions. While the thought of Rimuru battling alongside or against Goku is an exciting fan concept, understanding his true nature and origins within his canon series is key to appreciating his character.
Unpacking Rimuru Tempest's True Age: A Complex Evolution
The concept of "age" for Rimuru Tempest is far from straightforward. Before his remarkable reincarnation, Rimuru was Mikami Satoru, a human corporate worker in Japan who lived to be 37 years old. This human lifespan is the only traditional age he truly possessed.
However, once Satoru was reborn as a slime in a new world, the rules of aging completely changed. As a slime, Rimuru doesn't age in a conventional sense; instead, he evolves and develops. Think of it less like candles on a birthday cake and more like progressing through distinct life stages. Across various official sources like the anime, manga, and light novels, his "age" as a slime is referenced in different ways, often reflecting his developmental stage rather than chronological time. These references can range from around 2 years to 14 or even 17-18 years old. These numbers aren't about a yearly progression but rather markers of his significant growth in power, intelligence, and physical form.

Rimuru's True Origins: From Human to Heroic Slime
Rimuru Tempest's journey begins not in a fighting arena or on an alien planet, but in a mundane office building. He's the protagonist of That Time I Got Reincarnated as a Slime (TenSura), an incredibly popular isekai anime and light novel series. This means he was an ordinary human, Satoru Mikami, who tragically died and found himself reborn in a magical fantasy world, not as a hero or a prince, but as a seemingly weak, blue slime.
This reincarnation as a slime is the foundation of his unique abilities and growth. While his new world features elements often found in RPG video games – like stats, skills, and leveling up – it's important to remember that That Time I Got Reincarnated as a Slime is not an adaptation of a video game. Instead, it's an original narrative about creation, diplomacy, and immense power. For a full breakdown of his unique beginning and the world he inhabits, check out our article on .

Why Cross-Universe Power Comparisons Are Incredibly Tricky
The very premise of asking "how old is Rimuru in Dragon Ball Z" highlights a common desire among fans to compare powerful characters from different fictional worlds. While fun for hypothetical discussions, directly pitting characters like Rimuru against Dragon Ball Z's Son Goku, or even other anime titans like Saitama or Anos Voldigoad, is inherently complex. Each universe operates under its own unique set of rules, power systems, and limitations.
For instance, Dragon Ball Z's power scaling often revolves around Ki, physical strength, and transformations that multiply power. TenSura, on the other hand, deals with complex ultimate skills, conceptual abilities, soul manipulation, and evolution that defies conventional physics. How do you quantify Ki blasts against abilities that can literally rewrite reality, like Gold Experience Requiem from JoJo's Bizarre Adventure, or the overwhelming magic of Anos Voldigoad?
Consider the theoretical battle between Goku and Anos Voldigoad. While Goku's speed and physical strength are immense in his anime appearances, the light novel version of Anos possesses reality-bending, dimensional transcendence, and conceptual magic far beyond Goku's physical and Ki-based powers. This demonstrates the challenge. Learn more about these fascinating hypothetical matchups by diving into our analysis of . Similarly, the discussion around further illustrates the intricate considerations involved when contrasting different power systems.
Even within a single series, power rankings can be nuanced. In Demon Slayer, for example, the strongest demons are not simply ranked by brute force, but by unique abilities, regeneration, and even their connection to Muzan Kibutsuji. You can explore these intricate hierarchies in our detailed guide on . These examples collectively underscore why drawing direct comparisons between characters from entirely separate universes requires an understanding of .
Rimuru Tempest's Power: Beyond Age, It's About Evolution
What makes Rimuru truly remarkable isn't a simple chronological age, but his incredible capacity for evolution and his ever-expanding arsenal of abilities. As a slime, he gains powers by devouring and analyzing everything in his path, starting with the Great Sage skill (which later evolves into the ultimate skill Raphael, then Ciel).
His transformation from a simple slime to a Demon Slime and eventually a True Demon Lord grants him an array of formidable skills, including Universal Sense, Infinite Regeneration, and powerful Ultimate Skills like Beelzebuth (Lord of Gluttony), Uriel (Lord of Vows), and Veldora (Lord of Storms). These abilities make him arguably one of the strongest characters in all of anime, capable of altering reality itself.
Central to Rimuru's burgeoning power is his cast of loyal and formidable subordinates, none more significant than Diablo. A Primordial Demon, Diablo's power is immense, potentially rivaling Rimuru's own. His raw magic, terrifying combat skills, versatile unique abilities, and strategic intellect make him a force to be reckoned with, and his full potential remains largely unknown.

Clearing Up Common Rimuru Misconceptions
Given Rimuru's unique nature and the popularity of isekai anime, several misconceptions often arise:
- Children and Family: Canonically, Rimuru Tempest does not have children. Any references to characters like Natsuki Rigel typically stem from spin-offs of Re:Zero, a completely different series.
- Twins: Rimuru does not have twin siblings. The popular twin characters Rem and Ram are from Re:Zero -Starting Life in Another World-, where they serve as Oni maids. This is a common mix-up due to character name similarities.
- Angelic Nature: Rimuru is not an angel. He is an evolved slime who ascended to the status of a True Demon Lord. His powers are self-derived and granted through evolution, not divine origin.
- Romantic Relationships: While Rimuru deeply values his companions, his relationships are primarily built on loyalty, empathy, and friendship rather than romantic love. His main focus is on building and protecting his nation. Any speculation about characters like Shuna or Shion being romantic interests is largely fan-driven and not explicitly supported in the main narrative. You can read more about his social dynamics and the lack of romantic entanglements in .
- "Divorce" Glitches: A humorous "divorce" narrative involving Rimuru, Diablo, and Rem (from Re:Zero) is a non-canonical glitch or side quest mentioned in a game context, triggered by unusual interactions and a hidden marriage system. This is purely a fun, non-canon detail.

Beyond the Crossover: Embracing Unique Narratives
While the idea of Rimuru Tempest crossing over into Dragon Ball Z remains a fun thought experiment for fans, understanding his true identity, origins, and complex nature within That Time I Got Reincarnated as a Slime offers a much richer appreciation of his character. Instead of searching for his place in other universes, we invite you to explore the depths of his own incredible journey, where his age is less a number and more a testament to his boundless evolution and growing power.
