If I may humbly suggest something, letting [@Aeolian] answer the other Aeonheart-related details, whenever Manny reincarnates into a human form, what if it is a look-alike or at least similar in appearance to her original? I'll even generate new images for you whenever this happens. Because, there is a certain element to characterization and familiarity that is (sometimes, unfortunately) rooted in visual representation. This would also make it a lot easier for people to recognize Manny in a new form if the physical appearance (facial features) is somewhat reminiscent of the original.

This is not a must, of course! It's just a suggestion to help with character cohesion. Take it in, think about it, and that's it :)
