Corrin (SSB4)/Down throw
Assumes his dragon form and body slams the opponent beneath him, sending them flying diagonally forward and upward. Tied with his up throw as yielding the greatest knockback of any of his grab releases. Depending on opponent DI, at extremely low percentages can combo into a running up aerial, but just barely.
Throw and Hitbox Data
In dragon form, Corrin doesn't have hurtboxes. Corrin is still damageable after the throw release, however.
