- Every battle he's been in features some kind of doctor (medicine, philosophy, and the like).
- Each of his characters (except Brown) has a distinguishing characteristic that none of the others posess:
- Einstein- Only real-life rapper, only one to rap first
- Sherlock- Only one without wild gray hair
- Scrooge- Only non-genius character
- All 3 of Zach's fictional roles that he's played have died and then not died within their canon, in a sense.
- Brown was shot down by the Libyan terrorists in the first timeline, but wore a bullet-proof vest in another
- Sherlock (within the Sherlock TV show's canon) was thought to be dead after "jumping" off the top of a building
- Scrooge is dead in the "Christmas Yet to Come" timeline
- All of Zach's main opponents were played by Nice Peter, or at least partly: Stephen Hawking, Doctor Who, Batman, and Donald Trump.
- He has had the most guest appearances out of all other guests.
- He, George Watsky, Key & Peele, DeStorm Power, and Rhett and Link so far, are the only guest stars to have a rapping role in more than 1 season.
- He and George Watsky are also the only guests to have a rapping role in every season so far.
- He was the first and, so far, only guest rapper in Dis Raps For Hire.
- In a recent video, he said he's quitting the stage name "MC Mr. Napkins" and just keeping himself known as simply Zach Sherwin.
