Mr. Sunday

Origin
Mr. Sunday is a serial killer. He’s been at it a long time (he’s about 60-70 years old and still going strong). His method: He kills every Sunday, during church hours (pardon the pun, but he’s a “mass” murderer). He’s kind of set up, ostensibly, to be a recurring villain for The Seraph, but in reality, he’s just a huge ball of evil that is always in the back of everyone’s minds.
