ous box which is filled with horror-related comics. He is undead, describing himself as "neither living, nor dead", and has no problem siding with either. He seems to enjoy jokes of all kinds, and frequently makes bad puns about the book he is reading. He starts and ends each episode with a hearty bout of laughter, and refers to the viewers as "my children". He knows about Linkara and his show, and vice-versa, but to what level of meta-reality is unknown.
According to Lewis, he currently has no plans for including Moarte into AT4W so far. He has said he might, but it might be difficult to do. He also said that Longbox Of The Damned will be continued next year. Moarte is based, physically, on Lon Chaney's character from the lost film London After Midnight. His voice is a curious mix of stereotypical Eastern European vampire and Marik Ishtar's father from Yu-Gi-Oh: The Abridged Series.
A fan maintaining the Ask Moarte tumblr askblog created a backstory for the character, wherein he was once a famous circus magician who killed his rival to obtain the Longbox, and was subsequently sentenced to watch it for all eternity. Lewis saw the post and said he was seriously considering making this Moarte's official origin story.
