It isn't sure that every MS user wil have a special ability Itachi dnt have any spl ability and same with Madara(atleast for nw)........probably Madara or Izuna has the same ability as Sasuke did since Tobirams mentioned that he never seen a Enton that stronge and only MS user's that Tobirama knw are Madara and Izuna..............
Time-manipulated genjutsu is Itachi's special ability.
Sasuke has Amaterasu-manipulation.
Madara's are unknown, although it's implied he has Tsukuyomi.
Tobirama recognizing Kagutsuchi could be attributable to Izuna, so it's unknown if Madara has it or Amaterasu.
