What Powers Does The MC Have In 'Reincarnated As Kibutsuji Muzan'?

The protagonist in 'Reincarnated as Kibutsuji Muzan' inherits terrifying abilities from the original demon king. His primary power is blood manipulation, letting him control others by injecting his blood or reshaping his own into weapons. His regeneration is insane—decapitation won’t kill him unless sunlight or special blades are involved. He can also split into thousands of flesh fragments, each capable of independent movement or merging into clones. His senses detect human emotions like fear, making him a psychological predator. The most broken ability? Forced evolution—he can mutate his cells to adapt to any threat, like developing immunity to poison mid-battle. His presence alone weakens lesser demons, and his voice commands absolute obedience from them. The story cleverly shows how he balances these monstrous powers with human morality struggles.

I've obsessed over this series, and the MC's power system is a nightmarish twist on typical reincarnation tropes. Unlike protagonists who start weak, he awakens with nearly all of Muzan's original abilities, making him instantly overpowered but morally conflicted.

His blood manipulation is horrifically versatile. He can create organic whips sharper than steel, spawn eyes on his palms to see 360 degrees, or even craft disposable limbs to replace severed ones. The 'Biokinesis' aspect lets him alter his body density to phase through attacks or harden skin into armor. What’s chilling is his 'Demon Progenitor' trait—any human he turns gains powers reflecting their deepest desire (a vengeful victim might get fire claws), but they’re eternally bound to his will.

The series explores power limitations brilliantly. Sunlight burns him but won’t instantly kill like the original Muzan—instead, it progressively weakens him until he finds shade. Nichirin blades hurt, but his adaptive cells learn to resist after repeated exposure. His biggest weakness? Emotional volatility. When he panics, his powers glitch—regeneration slows, clones collapse—which adds tension to fights. Later arcs reveal he can temporarily 'borrow' abilities from demons he created, like using a spider demon’s webs or a bat demon’s echolocation, but overuse risks losing his human consciousness.

This MC redefines 'overpowered' in the best way. His powers aren’t just about destruction—they’re deeply psychological. Imagine being able to smell someone’s memories through their blood or inject hallucinations with a touch. His 'Blood Dominion' means any demon he creates sees him as a god; their loyalty is hardwired. But the kicker? His 'Cellular Memory' ability. He can absorb traits from demons he consumes—eat a lightning demon, gain electricity arcs in his blood.

Combat-wise, he’s unpredictable. One second he’s liquefying his body to slip under doors, the next he’s growing wing membranes to glide. The series smartly contrasts his powers with his human psyche. When he cries, his blood attacks become erratic. When he laughs, his clones develop grotesque smiles.

Unlike typical protagonists, his growth isn’t about new powers but mastering monstrosity. A standout scene shows him accidentally rewriting a victim’s personality by overusing blood manipulation, leaving them docile but hollow. It’s this ethical cost that makes his abilities haunting.
