do you think pre sk Yhwach can take down shinigami aizen without zanka no tachi?
Well I do believe that pre A Yhwach would defeat Shinigami Aizen (latter was scared of Yamamoto, whom Yhwach called weak comparing to 1000 years ago).
But Base Aizen, is Aizen without Hogyoku, Bankai or Shikai, Yhwach stomps there, man.
Didn't yhwach get fooled by SK even with the Almighty? Almighty immortality is restricted here unless you knew.
No, he didn't, Hashwalth stated that Almighty was activated in the fight against Ichibe and that it wasn't activated before (Muken incident, fight against Yamamoto).
Almighty's power is not only in reviving. But also in seeing the every future and understanding one abilities.
Aizen fooled Yhwach with his KS, but that doesn't matter much, Yamamoto was fooled as well (Aizen still admitted inferiority). Saying that pre A Yhwach is weaker than Aizen, only because he was fooled by KS, is like saying Shikai HItsugaya is stronger than Bazz-B just because he hitted him once with his ice.
