Ichigo got spanked by pre-almighty yhwach, almighty yhwach didn't even try, soul king yhwach obliterates current ichigo unless ichigo has some hax bankai, but nothing is more hax than the soul king so...Ichigo better do some dragon ball z stunt with Aizen to become IchiZen to even consider taking on soul king absorbed yhwach, because the way the "almighty" works, ichigo would get destroyed.
