These characters belong to a Universe called "The Unknown" .. see, The Unknown is a universe that connects two stories together, Tina and Bob + Hell on Earth, both are in the same universe and are directly tied to each other, but both are different stories.

Tina and Bob focuses on Hell and Heaven and how they operate while co-existing, following Tina, the daughter of Satan, as she has to take care of an incompetent, slow little Angel named Bob who took a tumble from heaven and fell into hell, but not in the traditional sense of a "fallen angel" seeing as Bob is not meant to be in hell, he accidentally fell and needs to find a way to get back up.

While on the other hand, Hell on Earth takes place directly on the planet, Earth, with obvious minor changes to earths inhabitants, containing Catboys, Monsters, Demons, Etc. — Hell on Earth is more of a work in progress than Tina and Bob is despite the fact that the characters and story have existed longer than Tina and Bob, but I suppose I was rather lazy than to do actual world building.

Hell on Earth is the main center piece of my fixation, I always catch myself thinking about the characters even tho I don't draw them often. I need to work on their lore, their story, their world, so that I can get more attached to these characters and produce content.

Both Stories are meant to be Comics one day. Hell on Earth being the main comic with Tina and Bob being the side / sister comic. Any Tina and Bob fans out there, don't fret because if I have to build hell on earth then I have to build Tina and Bob because they go hand in hand, the more I build one story, the more I build the other. You will have your content soon, give me time to work on this, 2023 - 2026
