Omniscience

Omniscience is the ability to have unlimited understanding and awareness of everything.

Characters with this ability
"He knows all ready, everything you want to tell him", Joshua describing God's knowledge

Barely any characters possess such an ability, however God possesses it, with Him being older than time itself.


 * God
 * Death (almost)

NOTE: Death has mistaken on numerous occasions, like: He says souls can't be destroyed, yet Crotto devour them, Demons are killed, and a high-ranking ghost relinquishes them from existence.
 * To be fair, we don't know exactly happens to demons or ghosts when they are destroyed, nor do we know that the Crotto actually destroy the souls they devour as opposed to just imprisoning them.
