All 11 Rimuru Evolutions: The Strongest Anime Character EVER | Reincarnated as a Slime Explained

Main plot / through-line

The video rapidly recounts Rimuru Tempest’s “evolution ladder” across the That Time I Got Reincarnated as a Slime light novels—showing how a seemingly “weak” slime becomes a multi-universal apex threat.

Each evolution is fueled by broken abilities, dangerous encounters, absorbing powerful beings, and upgrading his ultimate-skill arsenal—especially via Great Sage → Raphael → further Angelic and dragon-level transformations.

Notable highlights, key events, and big jokes

Origin setup (comedy + power fantasy)

Rimuru starts as a “negative” 38-year-old virgin and gets reborn with absurd benefits, posing the central question:

How does a slime surpass demon lords, angels, and true dragons?

The narrator repeatedly frames Rimuru’s power growth as “down bad” luck combined with system-breaking wishes.

Early “system abuse” with the World Language + Great Sage

• The World Language gives Rimuru a full kit: slime-body resistances, nullifications, and more.
• It also attaches a chat-GPT-like soul companion, Great Sage, effectively turning Rimuru into:

the smartest cheat code in the universe

Absorption spree: Veldora / Vora = huge head start

Rimuru absorbs his Storm Dragon friend, gaining:

• a mountain of magic-cells
• storm-themed protection/abilities

The video also leans into a gag: Veldora is basically “inside reading manga.”

Shizu fight: Predator goes wild

Rimuru saves Shizu from Ephr, absorbs the spirit, and gains:

• a new elemental/fire toolkit
• a human-form evolution

It also highlights how his Predator skill turns monster-battles into skill harvesting.

Degenerate explained like a game build

When Rimuru absorbs Shizu, he gains Degenerate, which can synthesize/separate effects—compared to combining abilities in RPG terms.

The narrator jokes that it’s “broken,” like swapping game loadouts.

Tempest gains an army via ogres (and name-based evolution)

Rimuru convinces ogres to join his new town. Giving them names triggers evolutions, culminating in a:

• connection skill that lets him access subordinates’ abilities

This is framed as a massive “team power scaling” moment.

Orc disaster + Demon Lord-level absorption

A species war is kicked off by mechanics likened to starve/Gluttony.

Rimuru stops the disaster-level outcome and absorbs the orc lord, creating Gluttony. This becomes a turning point because it lets him:

• grant/copy subordinate skills at range
• without consuming the original users

Milim humiliation chain (comedic villainy)

Phobio—spelled like an “unintimidating term” gag—gets humiliated by Milim, then foolishly becomes a vessel for Caribdis.

Rimuru’s absorption of Caribdis / Calamity delivers another major power jump (magic jamming + gravity manipulation).

Hinata vs Rimuru: “Rimuru gets embarrassed”

Rimuru’s first fight where he’s genuinely overwhelmed:

• Hinata uses Disintegration to shred spiritual matter
• Rimuru has to escape via a clone/backup

The narrator emphasizes this as rare near-death incompetence.

Demon Lord awakening (Harvest Festival massacre)

Rimuru becomes a Demon Lord by absorbing 20,000 souls, causing multiple skill evolutions (including infinite regeneration and universal-sense upgrades).

He also gets major ultimate progression, including:

• Gluttony → “Beel / Lord of Gluttony”-style angelic progression
• Food Chain evolving further to copy/allocate skills and power-scale alongside subordinates

Great Sage → Raphael → “C” → ultimate Angelic territory

A key progression milestone is:

• Raphael (Lord of Wisdom)
• later evolution into “C”

The video treats “C” as reality-editing-grade—able to manipulate information/virtual particle foundations.

This is presented as the core explanation for why Rimuru is different.

True Dragon transformation (Veldora + survivability becomes obscene)

Rimuru becomes a true dragon (the “fifth true dragon” turn), gaining:

• space-time control
• aging immunity
• the ability to override the world’s deepest mechanics

Multi-ultimate skill merging = “why can’t anyone beat him?”

Rimuru ends up with so many ultimate skills that his soul risks overload. So:

• Cel/C merges them into even more absurd outcomes
• generals get tailored ultimate kits
• “void god”-scale power concepts stack

Final boss framing (time stop is his only real “weakness”)

The video closes with Rudra controlled by Michael, arguing:

even true dragons can’t casually handle time stop unless they’ve evolved into a state that bypasses virtual-time constraints.

Rimuru ultimately eats Michael after Cel analyzes the situation, granting him every Angelic ultimate skill—implying godlike authority.

Ending twist / hype button

Rimuru is sent to the “End of Time,” everyone assumes he’s gone, but he returns—ending with the claim that he can even create a new universe using foundational “virtual particles.”

The lore suggests Nihil (non-existence) is the opposite force.

Jokes / narrator reactions sprinkled throughout

• The repeated framing: Rimuru isn’t supposed to be this strong—power comes from wish loopholes and absorption-system mechanics.
• Veldora is “just chilling reading manga” inside Rimuru.
• “Fobio” is described as the least intimidating name for a serious group (intentional disbelief).
• Many gamer/RPG comparisons (“like combining builds,” “ultimate skills are cheat codes,” etc.).
• Constant emphasis on impossible scaling: “how do you beat this dude?” / “this is broken” commentary.
