Space Pirate Rush
A command grab that drags its target across the ground before throwing them; this can also be initiated in the air to drag an opponent to the ground and do the grounded animation, or into the blast zone. The attack can rack up a great deal of damage very quickly, as grabbing and canceling in the shortest possible timeframe can deal as much as 12%, while dragging across a stage like Battlefield can deal well over 30%. The opponent can mash out of the drag to end it, but Ridley can also jump directly out of the throwing animation. The move otherwise ends when a ledge is reached, or in a stage with a walk-off, the blast line. It also KOs Ridley first if used as a sacrificial KO, similar to Flying Slam, and the move is easier to mash out of the more percentage Ridley has compared to the victim. However, the grab release does have advantages off certain stages against certain opponents, letting Ridley release them underneath a stage and recover, and even when mashed out of, Ridley has a chance to use a quick attack like jabs before the opponent can act should they be within range. The move has high base knockback but below average scaling, launching a fair distance at low percentages but not reliably killing until 130% and over, and the victim can survive even longer by using DI to aim their trajectory higher. If Ridley collides with a wall or other impassable object during the animation, the target is slammed against a wall and is subjected to a sort of stage spike. Ridley moves incredibly fast during the drag animation, even faster than Sonic's dash speed, and can crash into other fighters during the process. The move can also be use for recovery in the air though it's rather poor overall.
This attack is brutally effective on walk off stages, as Ridley's ability to cancel out of the move while launching the grabbed opponent can allow him to net very easy kills without sacrificing himself in the process, though it requires steady timing as Ridley can still jump into the blast zone if canceled too late.
Ever since Super Metroid, Ridley has been shown utilizing variations of a grab attack. This move is based primarily on the introductory cutscene for Ridley in Super Smash Bros. Brawl, in which he grabs Samus and drags her across the wall of his fighting arena. After Brawl's release, Metroid: Other M and Metroid: Samus Returns both reference the cutscene as an actual attack in Ridley's moveset.
