I agree with Unknown. Unless they happen to evolved to a point where they figured out how to use radio waves and eventually some variation of internet.

But maybe they took over Jimmy from accross the street, and are using his mind to control people who play jazz, becuase rabbits are their arch-enemy!!
Or maybe Jazz and Devan really do exist in a paralell universe and he wants to destroy the JJ2 comunity becuase in our version of the game Devan is defeated!!

...

Or maybe Fighter II is just being paranoid.
