This class crashes even supercomputers. It is also undiscoverable. With the comparison made above, this is the El Vacio or Hyperwave of JJT.

== Class 🈷️ ==
This class is even harder than class 🈂️. It goes beyond any form of physics. Not just roblox physics, or even real life physics. Any form of physics will be broken to make sure it's harder than the cannon JJT classes and class 🈂️. With the comparison made above, this is anywhere between the 60mmm to Super-Void of JJT.
* Forever RoorHELL (hardest difficulty ever mentioned in JJT)
** NIGH ROORHELL
** True RoorHELL's core
* MoonDeath
== Class 🈶 ==
In this class, the difficulty is the "author" and it controls the player. It goes beyond breaking physics and crashing supercomputers, and it is beyond undiscoverable. Class 🈶 is also a safety hazard and can leak your IP address. With the comparison made above, this is the MegaDeath of JJT.

== Class 🈯 ==
Attempts at beating, entering or even discovering this class could lead to you facing legal consequences. Players who attempt to reach this level will encounter giant chickens that can kill them in real life (which is beyond all forms of obstacles seen before), bananas falling from the sky that can get them arrested, and dancing penguins that do more than 10^1,000,000,000 (a multiversally huge amount) damage. These are just a few examples of the many strange and unpredictable obstacles that players will face in this class that defies all form of logic. This difficulty can also insert viruses into your computer, and/or turn your computer into a AI that will kill you IRL. With the comparison made above, this is the Dilly Impossible of JJT and this difficulty can even make your roblox character and then your IRL face turn into Dilly Impossible's icon.
