My UPG is that the spirit who shows up for a lot of evocations of Bael, including the one I sensed from E.A.'s video (which is, of course, not guaranteed to be the same entity he perceived) is a powerful and benevolent being, involved with genetically modifying a primate template to house human consciousness. A kind of “father god,” but without the toxic monotheism.
He shows up under the Cat, Toad, Man image (bonus tarantula/tentacle legs 
) and seems to have links to Marduk, Ra, Sekhmet, and possibly Kek. Marduk actually gives us different Names to call upon (Simon Necronomicon Spellbook is a good quick-access guide to these), so that again goes against the Bael I encounter being interested in setting up as the “one true” banana.
I love him, I could easily become quite obsessed with gazing on his imagery and sigil, and he gave me a sigil that people have found opens very quickly:
That’s my info-dump on Bael anyway, the name (afaik) means “Lord” so there may be other entities who show up when called under that as a title.
