Wario (SSB4)/Down throw
Throws the opponent onto the ground, then violently sits on top of them. While it has too much endlag to be used as a conventional combo throw, depending on the opponent's DI, it is possible to get some followups. If they DI down, Wario can do dash attack and lock them with the late hit. If they DI up and are a big character (like Mewtwo or Donkey Kong) then Wario can follow up into a back air and even kill with it. Should the opponent try to tech, he can buffer the bike, then punish all tech options except for teching in. Otherwise, the throw is actually unable to kill even at 999%, so it is completely unviable as a kill throw.
