Mewtwo (SSB4)/Down throw
Mewtwo quickly places the opponent on the ground and spins to slam them with its tail. While it was possibly designed as a throw which could properly combo into Mewtwo's other moves due to its low knockback, it has high ending lag. Because of this, it cannot properly combo into most of its moves, making it only usable to react to an opponent's options and punish it. If the opponent's reaction is read, however, it can be followed up with a forward tilt, forward or up smash, or a neutral or forward aerial.
It is Mewtwo's only throw to not be weight dependent.
