Categories from a prototype version of the old Fujita Scale. Once a tornado reached F12 strength (Mach 1) there was also speculation that there could be supersonic tornadoes (M1-12).

It's pretty much impossible in real life for a tornado to get that strong, and the actual maximum limit for a tornado is probably somewhere between 300 and 350 mph. But this is a hypothetical wiki and you can do whatever you want with it :)

Welcome to the wiki, by the way!
