So far I've somewhat worked out three characters for Strix's rogues gallery:

Count Corvus A self-proclaimed immortal who always seems to come back even after he's killed and claims to have lived for centuries and has the skills, resources and massive cult to back up his claims, and whom Strix believes is a prime agent of The Conspiracy.

Thomas "Crusty" Thermidore, one of Boston's most powerful gang leaders twice over. While formerly fading from prominence due to his advanced age, The Awakening transformed him into a lobster-like hybrid creature granting him not just ageless vigor but super-strength, a massive increase in size and an armored hide with superhuman durability to match.

Kabuki, a modern day ninja and assassin-for-hire who trained in ninjutsu alongside Strix and is even more skilled than him physically. He's driven not by money or by any sort of honor code or greater good but simply staging ever more elaborate 'performances' with his assassinations, as well as finding people who can provide amusement and challenge for him as a martial artist.

Not sure if these are any good. Took a mix of inspiration from different stuff. I'll admit that Count Corvus is basically Ra's Al Ghul mixed with Lord Deathman, at least. Feedback welcomed.
