Sorry but how can anyone criticize the purple blob when the reason why it looks like that is properly foreshadowed and explained as anincompatible fusion of mortal and immortal with the immortal part remaining after the body is destroyed.
The manga hasbullshit going on."they're fused at a celular level, so clearly they now reproduce asexually"
I don't mind a plot point based on half immortal half non-immortal. It's an interesting thing I was curious about how it'd play out. I just wish they didn't butcher Fused Zamasu's design using it.
