Top 10 Most Powerful Non-Human Isekai Anime Protagonists Revealed

Summary

The strongest non-human isekai protagonists include a high elf, skeleton magic knight, and half-alv enchanter.
These characters possess unique abilities and powers that make them formidable in their respective worlds.
From high elves to slimes, these non-human protagonists showcase the diverse range of fantasy races in isekai anime.

In many tales known as isekai, an individual from our world gets transferred or reborn into a fresh realm as a human. They might look different and possess extraordinary abilities that surpass the locals of this new world, but fundamentally, they remain humans. Interestingly, some isekai narratives present protagonists who are reincarnated as non-human beings instead. A few find themselves transformed into the characters they designed in a game, while others start life anew as monsters.

Considering the context, “Let me share with you the top non-human characters from isekai anime, arranged according to their displayed strength. It should be noted that this compilation mainly features living beings, excluding objects such as talking swords or sentient vending machines. The characters’ power levels are based on what has been depicted in the anime, even if the light novel or manga presents them as stronger. This is with respect to the current state of the story as it stands at the time of writing.

8. Cayna

A Traveling High Elf

Race: High Elf
Japanese VA: Eri Yukimura

One day, Keina Kagami finds herself awakened in an alternate reality that resembles her beloved game, Leadale. Instead of herself, she’s been transformed into her top character, a powerful high elf named Cayna. Although the fundamental game mechanics remain unchanged, the world now seems imbued with a vibrant sense of life, particularly among the non-player characters (NPCs).

Because Cayna possesses immense magical and physical power, very little can stand in her way or halt her ambitions. Consequently, she embarks on a journey across the globe, curious to explore this unfamiliar world and possibly encounter others who, like herself, are destined for greatness.

7. Arc

A Powerful Skeleton Magic Knight

Race: Skeleton
Japanese VA: Tomoaki Maeno

In this rephrased version: Arc, initially a gamer, unexpectedly gets transported into another realm, embodying his game persona, the Skeleton Knight, Arc. He dons a complete set of white, full-plate armor that shields him from head to toe. This heavy armor not only bolsters his defensive abilities, but also amplifies Arc’s destructive prowess.

In simpler terms, Arc is an exceptional knight, boasting not only physical prowess and martial arts skills but also a deep understanding of diverse magical abilities. These include offensive spells, teleportation techniques, and even the power to summon entities. When it comes to raw combat potential, Arc stands among the strongest characters in this roster.

6. Shiroe

The Cunning Half-Alv Strategist

Race: Half-Alv
Japanese VA: Takuma Terashima

Similar to other characters on this list, the main character from Log Horizon finds himself transported into a game world, embodied as a Half-Alv Enchanter named Shiroe. Born from the hybrid lineage of an ancient magical race called the Alvs, who are now extinct and only remembered through tales in history books.

While an Enchanter belongs to the Mage class, they excel in providing supportive magic. It’s important to note that Shiroe can certainly unleash powerful offensive magic, but it’s when he’s backing up a large-scale raid and directing his team that he truly stands out. From scrutinizing enemy attack patterns and administering the appropriate boosts to instructing formation adjustments for his numerous party members, very few raids will end in defeat with Shiroe leading the charge.

5. Diablo

The Timid Demon Lord

Race: Demon
Japanese VA: Masaaki Mizunaka

Similar to other characters in this list, the main figure in our story finds himself pondering a thought-provoking question: If they were magically transported to another realm, would it be as themselves or their powerful video game persona? This is exactly what happens to Takuma, who gets summoned into the new world, but not as himself – instead, he materializes as his legendary character, Diablo, the actual Demon Lord.

Remarkably, in this fresh realm, Diablo preserves his power, abilities, and formidable magic, yet he’s encountered an unexpected predicament – upholding his Demon Lord’s dignity. Beneath the surface, however, he remains the shy gamer, Takuma, as before.

4. Ainz Ooal Gown

The Ruthless Undead Overlord

Race: Undead
Japanese VA: Satoshi Hino

As an avid fanatic, I’d like to share my fascination with a unique character – Momonga, no ordinary undead! He’s the all-powerful overlord of the extraordinary guild, Nazarick, a realm inhabited solely by non-human beings. This guild boasts 41 members, each as remarkable as the next, and a multitude of NPCs, all of whom are not human. Unfortunately for Momonga, during the isekai transition, he’s left alone in this fantastical world, alongside his loyal NPC companions, while every other member remains absent.

In their transition to a fresh realm, Momonga and his band of companions assume a new identity, with Momonga becoming known as Ainz Ooal Gown. Upon arrival, he assesses the magical abilities of the inhabitants. To his surprise, their highest level of magic is only 6th-Tier. However, Ainz effortlessly wields 10th-Tier magic and even surpasses that with Super-Tier spells. Consequently, it’s no shock that he swiftly establishes himself as the most potent entity in this new world.

3. Kumoko

The Ingenious Spider

Race: Arachne
Japanese VA: Aoi Yuuki

Instead of being reborn as the most powerful entity in his realm like Momonga, Kumoko starts off in a new world as a weak spider creature. However, she possesses an advantage over other spiders due to her human-level intelligence, making her significantly smarter than her fellow arachnids.

In this new world, Kumoko’s cleverness proves vital as she is transported to one of its most perilous locales – a vast subterranean network teeming with formidable beasts. To endure and thrive, her only recourse is to grasp the intricacies of magic and progress as rapidly as feasible. Gradually, through determination and skill, Kumoko rises to become the dominant force within this infernal lair.

2. Rou

The Ambitious Goblin

Race: Goblin
Japanese VA: Takuya Sato

It’s not so terrible to be born as a goblin, despite their reputation. They may not be the strongest creatures, but they aren’t the weakest either. Their intelligence might not be impressive, but it’s enough for survival in a forest teeming with monsters. However, everything alters drastically when an ordinary man gets transported into their world through isekai reincarnation.

They bestow upon him the name Rou. Gradually, but decisively, Rou brings about significant changes in the lifestyle of the goblins. Through rigorous training and mastering magic, Rou uncovers the goblin evolutionary pathway, enabling himself and his kin to become stronger with every metamorphosis. In no time, he transforms into a superior being who effortlessly subdues gigantic monsters. He now heads a formidable group of goblin mercenaries called Parabellum.

1. Rimuru Tempest

The Ever-Evolving Slime

Race: Slime
Japanese VA: Miho Okasaki

In a state of utter astonishment, Satoru Mikami discovers his reincarnation as a humble slime. However, this unexpected turn of events comes with an extraordinary ability – the capacity to grasp anything at an incredible speed, particularly magical knowledge. Imagine it’s like possessing Tony Stark’s Jarvis, but instead of being proficient in human technology, it excels in magic.

Following the naming by the legendary Storm Dragon, Veldora, Rimuru undergoes rapid evolution at an astonishing rate. Barely a year after his reincarnation, Rimuru Tempest ascends to the rank of Demon Lord and assumes leadership over a nation of monsters known as the Jura-Tempest Federation.

It’s clear as day: His magical prowess has never been greater. He’s accumulated numerous Ultimate Skills, developed a distinct magic system based on physics, and discovered a means to revive his deceased comrades. With no bounds to his advancement, it can be confidently asserted that Rimuru is among the strongest non-human protagonists in isekai anime history.
