Let's discuss this eye, I don't think it's blind, If it was just blind it's strange he would open it during the battle like some kind of reveal
There's a colorful shimmer to it, I think it's a consequence of immortality like how one of mega chandelures eyes changes and is able to see into the afterlife
It's like they're existing between worlds, detached from both
AZ had one of his eyes covered at all times too
