Anos Voldigoad vs. Rimuru Tempest – A Battle Between Creation and Evolution, Where Logic Trembles

Anos Voldigoad vs. Rimuru Tempest: When Overkill Fights Overgod

What happens when you pit the Demon King of Tyranny against a reincarnated slime turned god with a built-in supercomputer? You get a fight that shatters logic, defies causality, and makes every other versus battle feel like kindergarten dodgeball.

This is Anos Voldigoad vs. Rimuru Tempest—a cosmic brawl between raw supremacy and infinite evolution.

Anos Voldigoad – The Walking Contradiction

Anos doesn’t follow rules. He rewrites them.

• Venuzdonoa – The Concept Killer: This sword doesn’t just cut through matter—it erases the reason something exists. Swords, spells, souls, dimensions—if Anos wills it, Venuzdonoa undoes it like a glitch in the matrix.
• Eyes of Destruction: One glare and you’re annihilated. These eyes disintegrate anything at the fundamental level, not through magic, but pure conceptual obliteration.
• Spell Creation on the Fly: Need a spell that reverses time? Creates a new world? Collapses a dimension in seven steps? Anos casually invents spells mid-battle like he’s making up dance moves at a party.
• Resurrection & Immortality: He can bring himself and others back with a snap. Even when erased, his origin—his very essence—remains, making true death laughably hard.
• Causality Defiance: He has returned from the dead before his killer even struck. Anos doesn’t just react to attacks—he preemptively invalidates outcomes.

Rimuru Tempest – The Infinite Evolution

Rimuru is the final boss of flexibility. A being who evolves beyond limits, backed by a divine-level assistant.

• Ciel – The Supreme AI: Rimuru’s ultimate weapon isn’t a sword or a spell—it’s Ciel, the ultra-intelligent voice in his head. She can calculate infinite outcomes, simulate enemy abilities, and instantly create new powers to counter threats.
• Turn Null – Infinite Energy Source: Rimuru’s god-tier energy allows him to generate any form of attack, defense, or reality-warping construct. If Anos can invent spells, Rimuru (with Ciel) can simulate and deploy counters in real-time.
• Ultimate Skills: Skills like Void God Azathoth allow Rimuru to erase space, time, and matter. He also possesses soul-manipulating, multi-layered barriers, and automatic resurrection protocols. Even if you kill his body, his soul-mind data is preserved in another dimension for revival.
• Absorption and Analysis: Rimuru learns from every encounter. Damage becomes data. Defeat becomes development. He adapts not just physically, but existentially.
• Evolution into a God: Rimuru isn’t just strong—he’s ascending, constantly, thanks to divine evolution. Every new threat is fuel for growth.

The Collision Course: Overwrite vs. Overcome

This fight isn’t about who hits harder. It’s about who rewrites the fight first.

• Anos can erase logic itself through Venuzdonoa, kill concepts, destroy the soul, and exist beyond causality.
• Rimuru can resurrect from soul data, rewrite laws using Ciel’s calculations, and generate new rules through Turn Null-fueled creativity.

So what happens when Venuzdonoa strikes?

• It would likely erase Rimuru’s body, maybe even his soul, but Rimuru doesn’t rely on singular existence. His essence is backed up in layers of dimension. Ciel may adapt before Anos’s next strike lands.

And what if Rimuru counters with Void God Azathoth?

• Anos has survived complete erasure, reversed cause and effect, and casually shrugged off death. Even absolute void might not be “absolute enough.”

The key difference?

• Anos is proactive—he dominates before the fight even escalates.
• Rimuru is reactive—but his evolution curve is infinite. The longer the battle, the more likely he adapts to everything, even Anos’s most abstract abilities.

Final Verdict: Who Wins?

This isn’t a clean KO or a flashy death scene. It’s a war between a man who makes the rules and a slime who becomes the rules.

If the battle is short?
Anos wins, likely using Venuzdonoa and reality rewriting before Ciel can fully adapt.

If the battle drags on?
Rimuru evolves, using infinite simulations and Turn Null-based creativity to develop defenses against even conceptual erasure.

But here’s the twist: both characters are written to be ultimately unbeatable in their own worlds. So when universes collide? You don’t get a winner—you get a new reality built by the clash of absolute will and infinite possibility.

Winner?
The Multiverse… now under renovation. And also a 50/50 battle

Key Points

• God vs. Demon King – Rimuru ascends to godhood with control over concepts, while Anos is the Demon King of Tyranny who rewrites those concepts just because he can.
• Power Level: Unmeasurable – Both characters operate far beyond traditional anime power scaling—think “what power ceiling?”
• Reality Manipulation – Rimuru uses “Imagination” and “Turn Null” to alter existence, while Anos wields “Source Magic” and the dreaded “Venuzdonoa” to shatter it.
• Combat Styles – Rimuru is the strategist who adapts and absorbs. Anos is the tank who bulldozes through logic with confidence and style.
• Conceptual Beings – Rimuru becomes a metaphysical entity; Anos can destroy concepts entirely, including Rimuru’s fancy godhood.
• Multiverse Madness – Rimuru can create and reset universes. Anos can destroy and recreate dimensions like he’s rearranging furniture.
• Battle IQ – Rimuru calculates and manipulates mid-fight. Anos just flexes and casually explains how you’re already losing.
• Resurrection Hacks – Rimuru revives allies via skill mastery. Anos? He resurrects himself and others just by snapping fingers (even from non-existence).
• Weakness – Rimuru has a slight delay when analyzing new threats. Anos has none… unless you count humility.
• Endgame Verdict – Rimuru thrives with prep and versatility. Anos dominates through sheer, unapologetic cosmic bullying.
