Rimuru's GREATEST Accident: How a Dying Bug Became Tempest's Most Broken Subordinate!
Did you know one of Rimuru's strongest subordinates started as a bug he found barely alive in the forest? It sounds like a fairy tale, but in the world of That Time I Got Reincarnated as a Slime, it's the absolute truth. That bug was Zegion, and his entire existence is basically Rimuru accidentally creating a monster – a final boss, even!
The Humble Beginnings: A Bug in the Great Jura Forest
At first glance, Zegion was nothing special. Just an injured insect in the vast Great Jura Forest, missing parts of its body and on the brink of death. Fate, however, had other plans, or rather, Rimuru Tempest had a moment of unexpected kindness.
Our beloved slime protagonist found him, and in a move that would inadvertently change the power dynamics of his burgeoning nation, Rimuru patched him up. He used his own slime body to heal the wounds, reinforced the damaged sections with processed magisteel for extra durability, and then, crucially, gave him a name. This act of naming, as fans of Tensura know, is never a small thing.
"Once Rimuru named him, Zegion stopped being a bug and started becoming a project."
And what a project he became!
From Guard Duty to Dungeon Overlord

After his miraculous recovery and naming, Zegion wasn't immediately a world-beater. He was first assigned to protect Treyni's settlement. But his growth was exponential. Treyni herself soon recognized his burgeoning power and recommended him for a far more significant role: the boss of Floor 80 in Rimuru's notorious Dungeon. Why? Because he was already too effective to leave doing normal guard duty!
Veldora's Touch: The Catalyst for Catastrophe

Then, as if Zegion wasn't already on an alarming trajectory, Veldora got interested. And when the Storm Dragon takes an interest, things tend to escalate dramatically for everyone else. Veldora personally took Zegion under his wing, training him rigorously. This intense mentorship pushed Zegion's evolution even further, until his body transformed from a beetle-like form into a humanoid powerhouse.
That training turned Zegion from that humble, half-dead beetle Rimuru saved into one of the most terrifying fighters in Tempest. His combat prowess became legendary, a testament to both Rimuru's accidental genius and Veldora's brutal tutelage.
Ascension to the Top: Mist Lord and Guardian
Zegion's journey didn't stop there. His power and strategic mind continued to develop. He later becomes the overseer of the 10 Dungeon Marvels, cementing his authority and proving his capabilities beyond mere combat. He earns the prestigious title of Mist Lord and, perhaps most impressively, joins the elite ranks of the 12 Guardian Lords.
Rimuru himself, no stranger to powerful subordinates, recognizes Zegion as one of his top three strongest, placing him right alongside the likes of Diablo and Benimaru. Think about that for a moment: one of Tempest's strongest war assets, a being capable of challenging even the most formidable foes, started as a half-dead bug in the forest.
The Accidental Final Boss
It's a testament to Rimuru's unique ability to attract and empower the most unlikely individuals. He truly looked at an injured insect, offered a helping hand, and accidentally built a final boss-level threat. Zegion's story is a thrilling reminder that in the world of That Time I Got Reincarnated as a Slime, compassion, a bit of magisteel, and a powerful name can turn even the most insignificant creature into an absolute force of nature.
