Stampede!

The Stampede is Yoshi's Final Smash for Super Smash Bros. Ultimate, replacing Super Dragon. When it is used, Yoshi dashes forward. Foes in his way will enter the Smash flat on their back as many Yoshisaurs stampede over their target, hence the move's name. Since it goes in one direction, the move is a directional/trapping Final Smash.

Origin
This move is a callback to the opening of Super Smash Bros. Melee. Here, multiple Yoshisaurs are running in the background. Their most prominent member, Yoshi, is seen separated from the group, but is part of the mob for the Final Smash.
