Casey Universe

Casey Universe, abbreviated as CU, and more commonly referred to as the Caseyverse, is a fictional universe based on the Casey family created by Tony Bark. Starting as series of loosely tied together webcomics, it has since evolved into interactive fiction.

Webcomics (2005-2007)
Casey Universe was informally established in 2005 as a loosely tied together web comics starting with The Furry Blue DJ, abbreviated as FBDJ, and later Z's Shorty Manga featuring Zack Casey, the main character and Tony Bark's former fursona, as the main character. The two were published simultaneously on DeviantART during the first year of their run before the latter was cancelled and merged with the former. FBDJ had many events that featured guest appearances of his friends' characters and vice versa that would prove difficult to translate over when Casey Universe was introduced.

Casey Universe (2009)
Casey Universe wouldn't be formally introduced until 2009 that introduced Furtropolis (formally Furville) and Aidan Cheddar and brought back Dr. Puppy as Saveli Cornell who's goal was to take over and control the city. It was Tony Bark's first attempt at a story and considered a fairly good attempt despite the holes. However, it the following two parts were never finished and later scraped but it became the world it created became for all future stories.
