Omniscience

Introduction
Omniscience is the state of having all knowledge, or in other words, knowing everything. A character that is omniscient knows everything that their opponent is going to do before they do it, and exactly what to do to win any fight. An omniscient character is still capable of being overpowered and losing, however. Also knowledge of other fictions is not a requirement for omniscience, so a character that knows everything about their own fictional franchise is considered to be omniscient.

There is also "Nigh Omniscience", for which a character or entity knows almost everything about their fictional continuity, with the exception of a small amount of information (usually what an even more powerful character wishes to conceal from them).
