- For a character from the novel series, see Fritz.
“GREAT! (now get out.) Note: First day on the job? Really?!?!”
Throughout the entire night, Fritz is functionally identical to Jeremy Fitzgerald in every way. Strangely, he even sounds exactly the same as Jeremy when breathing with the Freddy Fazbear Head on. However, based on the fact that his notice of termination listed "odor" as one of the reasons for him being fired, it is possible that he was also sweating and/or releasing bodily fluids similar to Mike, suggesting a panicked, nervous behavior.
- Fritz Smith is so far the only protagonist of the series to have appeared in only one night, as every other protagonist has completed at least five nights.
- Similar to Mike from the first game, Fritz was fired for "tampering with the animatronics" and "odor" upon completing the Custom Night. However, unlike Mike, Fritz was not given "general unprofessionalism" as a reason for his termination.
- On Fritz's pink slip, it reads that Fritz is the third employee, hinting that there was a first employee who took the night-shift job before Jeremy.
- This is also hinted by Phone Guy saying that the guy who worked before Jeremy was complaining about "conditions".
- Fritz's breathing while wearing the Freddy Fazbear Head sounds exactly the same as Jeremy Fitzgerald's.
- This may be due to game engine limitations only allowing for one breathing sound effect, or it may be an oversight by Scott Cawthon.
