Fantastic Rample, more commonly known as "Fanty", was the twin brother of Mingojerry Rample, better known as "Mingo". They were seen as fences for goods acquired by Malcolm Reynolds and the crew of Serenity. Although identical twins, Mal was able to tell the two of them apart, claiming that Fanty was "prettier." Mal also stated that he could tell the difference between them because "Mingo's voice was a mite higher than Fanty's," and "he could tell one from the other even over a bad wave."
