When the Final Smash is activated, Min Min will punch forward with her left ARM in the shape of a dragon, knocking any opponent away. The game will transition into a cutscene where other ARMS fighters will join together and use their ARMS to attack, before Min Min fires a laser from her Dragon ARM to blast the opponent against a gong to finish off the attack, afterwards ending the cutscene. Only one victim can be affected by the Final Smash at one time, though the initial punch will cause damage to bystanders.
In ARMS, each character has a Rush ability, which is filled up by the Rush Gauge as matches progress. Once the gauge is full, the player can activate their Rush, which is a flurry of punches (of varying appearances, depending on the ARMS used). Spring Man's role as an Assist Trophy utilizes the Rush as well, albeit more faithfully to its appearance in ARMS.
The Final Smash also looks similar to Ninjara's segment of Min Min's reveal trailer, where a bunch of different ARMS bombard him all at once. It could also be a resemblance to the ending segment of the initial trailer for ARMS, where Spring Man is falling down as a bunch of ARMS are being shot into the sky.
The gong that the opponent is launched into resembles the gong on Min Min's stage in ARMS, Ramen Bowl, which can be chimed if hit by a fighter's punch.
