Low Tiers (Lost Ones, Baby Widows, Searchers, Cartoon Bendy, The Butcher Gang) would be 9-A, as
they are capable of hurting Henry, though not by much.
Henry completely tanked the metal wall feat unharmed so they would upscale it due to being able to inflict harm
Mid Tiers would also be 9-A (anyone not mentioned in Low, High, or God Tier). These characters are
semi comparable to Henry or, in some cases, are
outright superior to him being able to knock him out.
High Tiers (Bertrum, The Lurker, Norman Polk, Giant Searcher, Brute Boris, Giant River Hand) would be at least 9-A.
Most of them can kill Henry and
Audrey in one blow and other Mid Tiers very quickly
All of this is correct, shouldn't be controversial at all
As for Low 2-C Bendy and Shipahoy Dudley...
First, Dudley scaling to Bendy. While he was indeed designed as a weapon to combat Bendy, it's worth noting that it didn't work at all. Dudley gets killed by Bendy without putting up any sort of fight. While Dudley was injured, he was still healthy enough to greatly harm Audrey.
Not to mention this implies Low 2-C Audrey, as she can harm him, which is highly inconsistent (she struggles to perform superhuman feats without the use of a weapon in general)
I think I could see a "At least 9-A, likely higher" rating due to him being stronger than most basic monsters within the cycle, but I can't see him scaling to bendy as he gets mauled and killed the second he actually enters a fight with Bendy
Now, for Low 2-C Bendy...
I certainly see the vision. I don't think this is a baseless assumption, but I have problems with it.
About the 'shaking the Cycle' feat. The
exact lines are this;
Wilson: The Demon's evil continues to spread. This world has begun to shudder...
Bendy: He's lying, Audrey.
So, you can see a few problems with this line. First, it could just be flowery language, describing how the Cycle is growing to fear Bendy. Second, Bendy claims that Wilson is lying. Now, Bendy is a huge liar, as is Wilson, so it's hard to tell who's speaking true here. I can say that the Cycle is indeed terrified of Bendy, however, Wilson is also contributing a lot to it...
Secondly, assuming Bendy did literally shake the Cycle, wouldn't that be 3-A or something? I don't think he shook time, if anything, just the physical space that the Cycle takes place in.
Anyways, moving on,
As for him resetting the Cycle when exposed to The End (the series' macguffin, which causes time within the Cycle to get reset/slightly altered each time), I would argue this is just Time Manipulation. I'm not entirely sure how these feats are treated, but this could give him a "Low 2-C via Environmental Destruction", since the Cycle is seemingly remade whenever he does this.
I don't think he should scale fully physically, as he does have some antifeats.
There's him getting staggered by the Projectionist (who can be killed by a gun),
and him getting his arm slammed in a door, causing him to retreat
Ultimately, my suggestion is to keep Bendy and Dudley at "At least 9-A, likely far higher" and then I wouldn't be opposed to a "Low 2-C with Environmental Destruction" to Bendy
