Pretty much any named character who is not present in official sources in Dullahan's
Maybe I'm a Lion Knk x Prototype crossover. You'd swear you were reading a spy thriller on the level of Bourne and Clancy with the exchanges between and actions taken by some of these guys. Keep a lookout for Mulder/Scully expies, a man wearing an out of place Hawaiian shirt, and anything involving the Three Kings and Áki Weisstein. Especially Áki, that magnificent bastard is still causing trouble for the modern day characters and he's been dead for 50-some years.
