Bowser Jr. (SSB4)/Back throw
Bowser Jr. spins around once and throws the opponent behind him, in a somewhat similar fashion to Mario's forward throw. The attack deals 12%, the most out of Bowser Jr.'s throws. It is also the strongest, allowing it to KO near the edge. However, it is still rather weak compared to common KO back throws, lacking knockback to KO under 150% at the edge without DI or rage, while also having high ending lag (38 frames) that makes it unable to follow up on and unsafe at low percentages. Combined with the fact that Bowser Jr. possesses a slow, yet only average ranged grab, this throw does not see much use in competitive play besides racking up damage.
The speed of this throw depends on the opponent's weight.
