Ever wonder what would happen if a succubat and cherubee procreate? Sorry, all I can think of is some sort of fallen angel type of thing from that.
like the hosts? they'd be able to inherit chitin patterns and all transformed features except what is physically the symbiote itself. so like, no butt wings, unless they were integrated with actual wings. if the tail is literally just the bat or bee, they don't pass it on.
the transformed self can be treated as the new baseline of what that person is, and will be passed along like any other traits, accounting for the like, randomness from having two parents.
