The Friday Night Funkin’ mod scene has produced some genuinely unsettling character designs, and Sonic Fatal Error sits near the top of that list with its corrupted, glitching aesthetic. This step-by-step tutorial breaks down how to draw Sonic Fatal Error from the angular devil horns to the clawed feet across 33 steps.
What Makes This a Challenging Draw
The tutorial runs 33 steps and ends as clean line art, so there are no colors to worry about. The complexity here lives in the heavy black fill areas across the face and torso, which require confident linework to pull off the two-tone contrast the character is known for. The asymmetric pose with both arms angled upward adds some balance work early on.
Sonic Fatal Error: Key Visual Features
- Round head with devil horns and stripes
- Large dark gaping mouth with sharp teeth
- Thin lanky body with long limbs
- Clawed hands and bird-like booted feet
- Heavy black fill on face and torso areas
If corrupted and horror-adjacent FNF characters are your focus, the guides for MX from Vs. Mario 85 and Neo Boyfriend cover similar territory with angular designs and strong linework. Tails Tsuraran Fox is another mod character worth checking out once this one is done.
Reading the Step Colors in This Guide
Each step image uses a three-color system to make it clear what to draw when:
- Red Color: lines added in the current step.
- Black Color: lines completed earlier.
- Gray Color: base sketch for structure.

Finished the Drawing? Show It Off
Once the line art is done, drop your finished Sonic Fatal Error drawing in the comments. Seeing how different people handle those heavy fill areas is always interesting. New tutorials get posted to Facebook and Telegram the moment they go live, a new YouTube video based on existing guides goes up every day, and Pinterest stays updated regularly, so those are good places to follow along. Other FNF mod characters worth trying next include Susman and Blake from Mount Sliver.
