Wii Fit Trainer (SSBU)/Forward throw
Wii Fit Trainer does a jump serve, using the opponent as a the ball. This throw has moderate combo potential, being Wii Fit Trainer's only throw with true followups on the vast majority of the cast at 0% (see table below). Forward throw is also Wii Fit Trainer's highest damaging throw, and can be used as a decent kill move near the ledge, although it typically won't kill until the opponent is well past 150% unless Deep Breathing is active.
Forward Throw True Followups
Forward throw is especially useful as a combo throw at low percents because it doesn't put the opponent into tumble, meaning they cannot DI the throw at all. Because of this, only the opposing character's weight, fall speed, etc. need to be taken into account when comboing off of forward throw. All followups in the table below are tested on opponents at 0% with no rage.
