Rank: Anti-Universe, EX
Saber's ultimate technique and the strongest Noble Phantasm in all of the Servant Universe. A "Final Episode Attack" that is meant to defeat the final boss and close out the Cosmo Guardian Trilogy with its hypest moment.
By overdriving her Cosmo Reactor, Saber achieves faster than light flight, cracking reality while pushing her opponent into something she calls "Saber Space". There, she accumulates all the Artorium particles who exist in the past, present, and future into a larger-then-the-universe blue energy avatar of her classic self, and brings down her cosmic-sized sword into the opponent, completely de-atomizing them in the process.
It is an attack exemplifying the coolest, most ridiculous thing she could ever conceive, and most of it is completely superfluous and unnecessary, but she is pretty proud of it. In other news, a certain drilling/animation studio is legitimately triggered and threatening a lawsuit, so Saber may be in trouble there.
