Zack Casey

Zack Casey, or Casey to avoid confusion, is Z's former fursona, avatar, and the oldest character in the ZACK universe. He was succeeded by Zack Bellow.

The Furry Blue DJ (2005)
Zack's initial appearance was in The Furry Blue DJ where his goal to be the greatest DJ he could be. John, Alex, and the fursona's of Z's friends at the time tagged along with him going on adventures while Zack worked towards his goal.

The DJ plot never amounted to anything substantial and was forgotten by Autumn of 2005 until a few years later. The formation of ZACK lead briefly to the idea of restoring the DJ plot but it wasn't until major changes and inspiration from other sources that Z got his wish.

The Furry Blue DJ (2016 - present)
Despite how much the character has matured and changed since his initial creation, Z felt that it'd appropriate to revert his gender, sexual orientation and appearance back to his late 2005/early 2006 variant, since he is no longer Z's fursona and would rather see Casey's story as a DJ begin and end properly.

In this 2016 reboot of FBDJ, Casey is now male, instead of a cuntboy; bisexual, instead of gay, a callback to a time when Z began to question his own sexual orientation; and wears full green hoodie, with blue shorts (as oppose to pants), with a blue hat.

Casey and original cast from the original Furry Blue DJ now reside in the outskirts of Furville in an cul-de-sac, reminiscent of Z's old home.

The overall plot remains roughly unchanged from the original. Though Zack's inspiration for doing so is now a famous underground DJ at Furville's downtown district.

Personality
In both original and 2016 reboot, Casey is a cheerful and outgoing who likes listening to laid back and upbeat music. His lust for male underwear lead him to steal of John's over the weekend. However, he later returned them the following Monday after feeling bad.

Despite his love of technology, Casey often dislikes smartphones in favor of owning tablet. This is mostly due to contracts, subscription fees and planned obsolescence that make it impossible to use in the long term as oppose to their "dumber" predecessors. He also has gripes with the TPaw Corporation, after learning about their past business practices and former monopoly on desktops.
