The Kasai Rex is a gigantic theropod cryptid from the Democratic Republic of the Congo in Africa.
It is said to be a surviving species of theropod dinosaur, such as a Tyrannosaurus rex or Giganotosaurus; as the cryptid's namesake; although quite a low possibility; if its indeed an alive African theropod it's likely a species of spinosaurid; abelisaurid; allosaurid; or a carcharodontosaurid; as there have been no known species of tyrannosaurid ever depicted and recorded in Africa.
