He’s an EXE that’s the complete opposite of Fire.exe. There isn’t anything too deep about the concept—I just wanted to try something like this for fun.
Firewall isn’t possessed by another being—he’s still Sonic himself and fully in control of his powers. ↔ In contrast, this one was possessed by a demonic entity and is constantly fighting for control.
This drawing shows him at a stage where “Sonic” is still present. When he loses control, he’s supposed to shift into a slightly different form… but I don’t have any art of that yet😅 He’s been around as a concept for a few years now, and I still haven’t fully nailed down that design.
