Yhwach was the villain that gets hyped so that Kubo could suck Aizen dick by throwing him in the final fight
Honest to god, the only time Yhwach ever got ANY type of glaze that Sukuna got... was when he made Muken Aizen look like an absolute chump... and even THAT was only truly clarified in an interview at the end of the day.
At least despite lolAlmighty his fight with Ichibei really had him going fully serious to deal with Ichibei even if it asspulled stuff
He also went fully serious against Ichigo and the dude still lost to a tired and fucked up Ichigo without his Hollow and Quincy Powers with just his Bankai...
The dude was literally doing everything possible so that Ichigo wouldn't even HAVE his Bankai against him, it was that ridiculous looking at it.
Speaking of it i hope the anime redo the fight to actually make almighty to actually make sense
Honestly looking back at it, The Almighty was actually explained pretty well but the problem is that people basically went full VSB on it without thinking on it for 2 goddamned seconds and believed it was impossible to deal with for anyone(Despite Aizen and Uryu easily having the means to deal with it) and that it has actual genuine flaws.
If anything, I do want a better explanation only to really have it rubbed in how limited it is and how genuinely Uryu can body the dude with The Anti-Thesis.
