The blue fox, now fennec, you've seen throughout, up until the introduction of Max in Let's Ride, is named Zack Casey. He was my first original fursona, that was a brief rip-off of the Riders version of Tails that Max now pays homage to. Back then, I was simply known as Z or ZC because of my username. Max is primarily seen in my main account, tonytins, but he lacks the true historical context that this account provides, so the two are technically in a "shared universe" now. xD

Zc456 was a partial acronym of my ancient AOL username that had my real name in it, at least the C portion. In the mid-2000s, the username itself began to get shorter and shorter, originally three Zs down to simply one, before I finally settled on "ZC" with "456" added to compensate for how short it was for DeviantART. When people began calling me Z, I had to reverse engineer my username to avoid revealing my real name, and I called my character "Zack Casey".
