The All
Appearance
The All is the megaversal entity who owns the SENTEN megaverse as a whole. The All is a symbolic representation of the creators of the comics, including writers, inkers, and even publishers.
In-universe, the All was created from the heat of the megaversal blow. Hours after the original six multiverses formed, he did. Immediately, he created a shell, and then the events and nouns of the multiverses, scattered across universes.
