So, after
getting SomebodyData's permissio (Because I don't want to get too off-topic, & he made this thread & is an Administrator), I'm just gonna bring up some likely anime-only scaling that's mostly for the humans.
Note that this doesn't mean I think manga discussion is over; Just that it's a bit postponed with everyone burned out & Data & Kukui having limited internet access.
So....
Small note: I know Kemo's actual name is Saruwatari, but "Kemo" is much shorter. Most of the English names are, & a lot of us know them by those names, so that's what I'll use for now.
First off, I don't think it's unreasonable to assume Tristan & Joey are comparable, given their history together as fighting delinquents.
Episode 8 - Tristan is able to turn Kemo upside down & throw Kemo over his shoulder a horizontal distance of probably at least a foot. Kemo manages to move his body in mid-air, righting himself & landing on his feet.
Kemo then hits Tristan with a jump kick, knocking Tristan flat to the ground for the viewers to see; Until Kemo leaves, Tristan is off-screen & does not get up nor speak until Kemo leaves.
Going by this, Tristan is likely 9-C for lifting a grown man upside down & over his head, & throwing him a short distance. Kemo should be comparable, if not superior to Tristan for making a landing from the throw & flooring him with one attack.
Episode 20 -
Kaiba encounters Kemo. He prevents Kemo's gun from firing by jamming the hammer of the gun with a card as Kemo is starting to pull the trigger. When Kemo tries to attack him, Kaiba dodges, winds Kemo with an elbow to the chest, & throws him to the ground. Kemo doesn't manage to right himself, & Kaiba has him take him to Pegasus's castle.
Going by this, Kaiba should be comparable or superior to Kemo, for outmaneuvering him, winding him with a single hit, & is probably 9-C being able to throw a grown man a good distance.
Episode 55 -
Tristan punches Joey. This knocks him into the air & back a bit, & Joey ends up on his back on the ground. (The fandub of the scene is because it seems to use the original footage, which is hard to find on Youtube.)
Tristan likely scales to Joey for being able to damage him & knock him back, as well as presumably having fought with/alongside him in the past.
Episode 136 -
While possessed by Marik, Tea performs a minor strength feat, grabbing a handlebar, doing a handstand on it, turning around, & leaping above Yami Marik, landing a few feet behind him. (Pardon the foreign dub. Also, music & VAs aside, the scene seems to be identical to the subbed version, feat-wise.) She also dodges his swing of the Millennium Rod in this scene, & survives being knocked to the ground by its telekinesis.
I would attribute the dodge to Marik's reflexes, not Tea's, since it's his mind active, but the strength feat -propelling herself a good distance into the air from a handstand on a handlebar- & surviving a hit from the Millennium Rod should apply to Tea; It's her body, after all.
Because I'm lazy & sleepy, I won't mention the episode numbers for some of this other stuff. Most of it, we all know of anyway, or have calcs for.
Yami Marik has a 9-B feat. The electricity manipulation from that scene might also be worth calc-ing, if it's possible.
The video source for that feat has been taken down, but it should be possible to find elsewhere. Assuming it's physical, I can't think of anyone it scales to. If it's telekinesis, it might scale to whoever's been hit by Marik's Millennium Rod's TK & lived. AFAIK, that's just Tea right now.
At the end of Yugi's duel with Weevil, the train they're on derails & falls off of a cliff. Yugi, Tea & Weevil experience & survive this. It's a 9-B feat, although I think it might not scale to Weevil; He didn't have a soul in his body at the time, & the next time we see him, it's in a hospital at the end of the arc when he has his soul back.
So, IMHO, for all we know, Weevil got all of his bones broken & internal organs ruptured but managed a miraculous recovery because the doctors fixed his soulless body at the hospital & when he got back he was in good condition again.
Likewise, the video source is down for that feat as well.
Nonetheless, the feat scales to Yugi & probably Tea, putting them at 9-B durability if it does.
And given that Joey was able to punch Yugi & knock him back, sending him flying, it's possible this scaling extends to Tristan, Kaiba & maybe Kemo.
Obviously, there's other possibilities; If Marik's AP with the Millennium Rod were to be assumed to be applicable to his clashes with Bakura's Millennium Ring, which could scale to Pegasus. But those scenes are arguably Shadow Games, so it's questionable.
Other neat stuff:
1. Timeaus's dragon form has some good feats in war flashbacks.
2. Joey vs Valon is full of feats. The most important are Joey surviving Rocket Hermos Cannon being used on him -because it scales to him armorless- & maybe Lord of the Red's explosion when it & Armored Valon clashes. Reasoning being Lord of the Red requires using Red Eyes Black Dragon to summon it.
Which means that explosion may provide an indirect means of providing AP for Anime Red Eyes Black Dragon.
If you're all wondering, Valon is probably 10-A or 9-C in base, higher with his armor. Other than that, he's unremarkable, because most of his feats require his armor.
Also, the feat from the end of their Duel requires Joey using one of Valon's cards in a fusion he never uses again, with Hermos -which he loses at the end of the arc- & it scales to Valon & him in an armor he never uses again. From a scaling point, it doesn't change many profiles, & it may be an outlier. From a calculation standpoint, & given that contributing factors to its yield may involve luminosity, wind, & electricity, it would be difficult to calc, if at all.
Hence me not considering that big pillar of light Joey & Valon made very important.
Anyway, thoughts on all this, all? There's probably a bunch of monster scaling I'd wanna get to later, & I definitely wanna check out the manga feats later, so I'll probably continue this later.
