This was technically created before Mr. Theodore Trapdoor, but I only just made the "money shots".
Here we have Jackie Nightmare, a mysterious warlock who weilds the power to project fear into a person's very soul. Given the right target, this can be deadly in itself, but in case that doesn't work, Nightmare's loyal foster parent, The Jokester, will always be standing by to deal the finishing blow to any do-gooders. The Jokester found Jackie as a child and is the only one to know their true identity. Until that's revealed, they only respond if they are called "Jackie Nightmare".
My design for this character was to create something that looked slightly scary, unlike most of The FANG characters who are rather comical. I made the decision to very roughly colour their clothes so that the clothes look like they were hand made/sewn/dyed (by the Jokester) as opposed to Mr. Trapdoor who has his suits tailor-made.
Jackie also has a dark sense of humour and a competitive nature.
