Dracula has the protomolecule, confirmed?

Dracula in an otherwise realistic sci-fi setting would also have some potential.

Immortal unless he's killed, which he was.

There's a Dracula "sci-fi western" in development now, and it wouldn't be the first sci-fi film to feature vampires. Blade Trinity was fairly sci-fi and featured a resurrected Vlad III. There are also a whole bunch of low-budget independent films, because the character is public domain.

So it's been done, but I wouldn't say it's been done well. Technology and the ubiquity of cameras make telling vampire stories logistically complicated. Like, they always need to come up with a bunch of handwaves to explain how coffins fly on airplanes piloted by a bunch of human familiars, and how the old legends about running water and being invited in are apocryphal superstitions.

How do vampires handle high g forces, I don't believe it's ever been addressed. Presumably the ability to turn into a bat would lower his mass and help.

Hrm....is it only our sun that's a problem for him? Like how our sun powers superman but Krypton's didn't?

With a skeptical brow raised, the count begrudgingly sipped from a glass of Coca-Cola, a recently invented American beverage vastly different from the Romanian wines of his cellar. "Passable," he muttered under his breath, with a reluctant nod, betraying centuries of noble pride. Yet, as the night unfolded, a subtle smile crept over his pale face.

It is historically plausible for a samurai to have sent a fax to Abraham Lincoln

Any stranger than him being a vampire?

Of any "class/type" of person to be doing something like that a noble is the most likely. High standing and money gives you easier access to things.

He could travel to Baltimore for a bridge tournament.

The fax machine, actually

Yeah, meanwhile in reality Karl Marx sent a letter to Lincoln.

Well, yes, but I don't think there were lines connecting the two.

That said, Matthew Perry (not that one) had already reestablished relations with Japan during Lincoln's time

After 1904, instead of using fresh leaves, Coca-Cola started using "spent" leaves – the leftovers of the cocaine-extraction process with trace levels of cocaine.[77] Since then (by 1929[78]), Coca-Cola has used a cocaine-free coca leaf extract. Today, that extract is prepared at a Stepan Company plant in Maywood, New Jersey, the only manufacturing plant authorized by the federal government to import and process coca leaves, which it obtains from Peru and Bolivia.[79] Stepan Company extracts cocaine from the coca leaves, which it then sells to Mallinckrodt, the only company in the United States licensed to purify cocaine for medicinal use.[80]

So it still has coca extract, just not the cocaine part.

That's why they named the company "coca" cola.

A lot of things used to be a lot cooler. My doctor has never prescribed me opium and laudanum for a cough.

Why?
