Continuation to this post, where characters of a supernatural species will have dialogue in a different front from the rest of a the typeface.
This post pertains to @aroace-get-out-of-my-face's AU, Multiverse Time with Dr Pine. Which crosses over into another Sesame Street AU, due to that fact that Dr. Pine's evil counterpart, Dr. Birch, has a very... complicated past, most notably that his ex-husband is a multiverse variant of Count Von Count.

Notes
The Counts handwiting is Edwardian Script ITC, the closest I could find that resembles his signature as given on this collectible Sesame Street mug:
Puppet Dracula, is the original vampire of his dimension. Although he closes resembles many legends of Dracula, including the IRL Vlad the Impaler (Vlad III / Vlad Țepeș may or may not be his actual name), he is thousands of years old so he does not follow the IRL historical timeline.
The Von Counts and Von Dahling's are different branches of the same family, and they are Dracula's direct descendants. The Count, Dahling, and Ervin are all Dracula's 4x great-grandchildren, with Delavay being his 5x great-grandchild, and his first (confirmed) dhampir descendant.
Dahling and Natasha's fonts directly relate to their element - Dahling having control over rain, and Natasha having control over winds.
Countess Von Backward's font has two versions - usually, it's Kingthings Frontwards, but when she's actually counting, it's Kingthings Backwards.
In the Vampswap where Birch is the Vampire and The Count is the mortal, Birch and his brother Leopold are both vampires. As twins, they are still a matching set, so they speak in the same font (which is a further reference to how the canon Stan Twins can mimic each others voices).
Bob Cryptogram is Multiverse Time with Dr Pine's version of Bill Cipher, which is why he uses the same font.
When Abby is speaking spells, her font changes to that of her mothers.
