Fan Casting Walter Katz in Blood: The Last Vampire (Season 2)

The main antagonist of season 2 and an overarching antagonist behind everything that's been happening in the whole season. He is believed to be the strongest chiropteran, earning him the moniker "King of the Darkness". It's not just a mere nickname as he shows his tremendous powers that proves him to be one of the most powerful chiropterans to ever exist, presumably exist since centuries ago, hence why he called Saya his "mother", as Saya is the original vampire who had lived for centuries and her blood is believed to be the one that created the chiropterans.
