The Vampire Diaries: Superhuman

The MC is transmigrated with three things - the Super Soldier Serum Captain America was given, a further serum used by Deathstroke to improve upon the first serum and finally, a nigh-indestructible claymore. Worst of all, he finds himself in the late 19th century, inside a secret organisation in the Vatican City, naked and holding the claymore to his body. He soon finds out there's more to this world than just that, however.

(A/n - MC will start his journey off in the movie of Van Helsing (2004) but the world is much bigger than that. I'm basically smashing together Underworld and The Vampire Diaries/The Originals to make one massive world of supernatural creatures. Oh yeah, the MC is a good guy and a religious guy. Not a fanatic or one of those insufferable hero-types who think they're better than everyone else but a guy with good morals who wants to do good and believes in God. If that isn't your cup of tea, you might not wanna read this. Religious stuff won't ever be the forefront, however, just a part of what the MC believes in.)
