How do we know that it only works on humans? Theoretically it works on any living organism as long as it has an identity.
Yet it hasn't seen kill anyone besides humans and doesn't even work on shinigami's, and why would it work on people who are technically not physical by any means? Non- corporality for instane, gods, cosmic beings, who who don't have any shape or form, They may use physical avatars, but their essence exists in a nonphysical form. Sometimes, this could be spirit, energy, etc. Non-corporeality, said being's apparent body is their true body, it just can't be affected by physical forces. A non-corporeal being generally does not have any kind of defined body, they're not a physical entity.
and abstract beings, which is an entity that is the embodiment of a concept, such as love, hate, time, power, etc. Most abstract beings cannot be destroyed or killed unless the concept they embody is completely removed from existence. Thus makes abstract beings incredibly hard to kill, sometimes considered second only to omnipotent beings. Conversely, if an abstract is more easily destroyed, this usually results in the destruction of the concept they embody.

How does the death note kill a supposed concept :|???.
and it clearly states the HUMANS whose name is written shall die, and like I said anyone who can reality warp with omniscience can erase light from existance before he has a chance to shit, and I can name many characters who are capable enough.
So he actually doesn't deserve a spot.
Omniscient = all knowing. They would know they're destined to die : the wouldn't be able to change destiny
Yes they would, most known omniscients in fiction can reality warp (usually omnipresent as well, or infinite speed), light gets fuked, they erase him on an atomic level before he even has a chance to pick up his pen

..omniscients also have ultimate pre cog ...and know exactly what to do to win any fight. But even so, they're still capable of being overpowered.
But by a human, who has human level inteligience? No, I don't think so.
The list is fine, round of an applause for u, but I'm not accepting light to be here, it utterly makes no sense..
Pretty strong... but it doesn't mean he's invincible. To be top 4 he has to have no weaknesses. Does he have weaknesses?
No notable weakness.
Never heard of the Lord of nightmares.
Figures, LOOK HER UP, she's second to tenchi, has metaverse level+ DC and no limitations, infinite, and can't be harmed in any given way....I recommend u add her c:
Yeah it was a joke lol, made for the dragon ball fans, it's what they'd say..
Molecule man has too many weaknesses. Not only this but manipulation of matter is a power that most of these characters on this list have (+ They have more.)
Yeah kinda, but the presence deserves a spot though *bump*
And alien X too

Broken list. Whis definitely has to be in the top 10 strongest in all of fiction.
He gets raped by dark Schneider who isn't even top 10 in anime let alone fiction..
