Reginald Redclaw
From Jenny Everywhere Wiki
In one universe, Reginald Redclaw, also known as the Demon Majordomo, was a tall demonic, undead butler with a red, skull-like face and glowing eyes. He was a famous specter, known to Jenny Everywhere, who described herself as “a fan of [his] work”. He served Strach, the Abstract of Terror, at D'Ismay Mansion; he answered the door when Jenny visited the Mansion on Halloween night, wanting to speak with the master of the house. He attempted to rebuff her, but she made her way past the demon butler easily. (COMIC: Jenny Everywhere in the House of Terror)
