As he takes over the powers of each newly created character, he has all the abilities in fiction, in reality and beyond reality. But his most notable and famous abilities are: Transcendent Omnipotence, Transcendent Omniscience, Transcendent Omnipresence, Transcendent Immortality, Plot Manipulation, Law Manipulation, Immortality, Conceptual Manipulation, Fire Manipulation and Creation.
Fire S consumed
Horus, granting additional abilities.
It is impossible to copy the Fire S abilities from the page (even if they were slightly or heavily modified at the same time), because in this case the character who received them will become weaker than the zero-dimensional preon.
He is also immune to all abilities that he possesses (and to all abilities and even what is above the concept of abilities) so they can't be used against him.
Fire S cannot be influenced in any way without his permission, even if it is written in the character's abilities that he ignores this rule, then he still does not ignore it.
Fire S cannot lose, even if it is so laid down by fate. He just took away such an outcome for himself. And even if he "loses", he will still win. He cannot be absorbed, nor can his powers. He is beyond the beginning and the end.
Even possessing an infinite, immeasurable, irrelevant, or any other number of abilities/hacks is not enough to describe, because the number of his abilities far exceeds "infinity", and everything that has been described here is only an infinitesimal part of his avatar, for the Fire S himself goes far beyond our understanding and imagination.
He has immunity from gags, memes, and parody characters. He is have immune to such things like "composite", even "comp-verses", "comp-characters" and "comp-victory" cannot affect him.
Even if you create a character using all variations of letters and symbols from all languages, they will still be weaker than Fire S.
