As it concerns just from Mid Tiers to Top Tiers and will take time going to each one and their scaling imma go over the existing characters affected
Mid tiers
-Jinpachi (except last key)
-Marshall Law
-Lei Wulong
-Jack 5
-Jack 6
-Anna (except for T8 self)
-Nina (except for T8 self)
-Alisa (except for T8 self)
Alisa
fights a Jack 6 and kills it in battle, Nina
fights Alisa and wins the first time, then Alisa gets Nina to her knees the second time they fight, Anna is Nina rival since the very first game and had plenty of fights,
this is one of them
Jack 5 is
capable to defeat and kill Jinpachi in battle, both Lei
can beat Jinpachi as well, Lei and Marshall Law are
comparable to each other, their battle even ends up in a tie
High Tiers
-Lee
-Feng
-Raven and Master Raven
-Victor
-Dragunov
-Eliza
-Jack 8
-Jack 7
-Nina
-Anna
-Alisa
-Paul
-Ogre (except Monstruous key)
-Bryan
-Yoshimitsu
-Kazumi/Devil Kazumi
-Kuma 1 and 2
-Panda
-Asuka
-Lili
-Josie
Lee
beats Alisa, pointing out he would rather not fight her, as he manages to block her charging attack, Alisa is basically bloodlusted in this instance, so he didnt go all out on her yet still won, in his
special intro with Lars he matches him in a clash of kick vs punch, which going by Lars words would be when Lee goes all out
Nina in Tekken 8 got stronger then before, she manages
to harm Lee and is
even with Eddy Gordo, whom as you have above yourself can tank 4 Jack7s self destructing and even earlier on, fights Jack 7s individually, she manages to
fight more or less evenly with Reina, even pointing out Nina is pretty tough and Reina scales to the Mishimas, an example being matching Heihachi in
their special intro, Anna in this game also got stronger, matching Nina in
a clash of their special intro
Alisa also grew stronger in this game, against Jack 8
she does relatively decent, while Jack 8 has the edge more, he was made so powerful that two other high tiers together
were required to put him down, in his ending he even
beaten other high tiers, like Lee which i talked about earlier, so its a matter of facing a more powerful model of the Jack series, Alisa also
beats Lars in a fight, most likely didnt take her on with all he has, but given he is clearly defeated here still speaks volumes to her power
Eliza
defeats Claudio, somebody
that ties in a clash with Azazel hand, as well as
beating him in his ending, Josie fights against Kuma 2,
in his ending he wins, but he still points out, she is a tough opponent, worthy to get her on his team, Kuma 2 can
defeat and
give Paul a tough time in battles, to Current Paul that is, Paul is his prime is powerful enough to
one shot Kuma 2 and fight Kazuya
to a draw, so whatever Current Paul does, Prime upscales from that, also Current Paul is shown being able to
defeat a Jack 7, King
struggles a bit with a Jack 7, King is comparable to
Paul and
Jin and coming back to Kuma, the first one, he is
considered a sparring partner for Heihachi and
trains a lot with him
Bryan
scales from Paul, they got two instances being depicted evenly matched, Feng
casually with one hand makes a fool out of Asuka, he also
scales to Leroy, somebody who
fought and did well against Jin, Yoshimitsu matches Bryan in
a sword vs minigun clash, he also
stopped Bryan in the previous tournament from wrecking havoc,
here is a cutscene too of that
Panda is comparable to
Kuma and
Paul, Kazumi
does well against a young Heihachi and in devil form later on by the end, she makes him catch his breath a little bit, takes a punch from him, a few moments later she gets back up again, this Heihachi is
on the level of those like Feng, Ogre is
comparable to Jin, his True Ogre form is
powerful enough to harm and take many blows from a Jin amped by the devil gene (red glowing eyes)
Raven
faced off against Heihachi till he was ordered to leave and can
beat Jack 7s, Dragunov is
comparable to Raven, Master Raven can
beat Dragunov and as you see she calls in question how he was giving Raven trouble and also calls him an imbecile needing more training, Victor
beats Dragunov and they have a rivalry too given the old man dialogue towards him, he is also shown
comparable to Raven
As for Top Tiers, its Akuma, Heihachi, Kazuya, Jin, Lars, Monstruous Ogre via
this against Jin and Azazel via
this against Lars, the others their scaling in the profile is pretty clear cut on scaling, if you want me to give evidence on those, will do next time i get on laptop tomorrow
There is a whole lot more, but it will take too long, most are gonna get tackled in a verse wide revision down the line, its a very lenghty one, but yeah thats the scaling to have an idea on each of them, the one shotting of Jack 6s and the 4 Jack 7s self destructing being tanked by a high tier provided by you along what i wrote here should help yah figure out easier and get an idea where each of them are sitting in terms of scaling
