The Four Furries of the Furpocalypse are the furries that invaded the Repl.it server, eventually leading to the furban and its repeal.
The original two members of the FFF (Four Furries of the Furpocalypse) were Zavexeon and Haziallat.
Later, Edwin was converted to a furry and joined the FFF and superwhiskers soon followed.
The user Little Nomster recently joined the Discord expressing similar interests. It is TBD whether or not they are to be included.
