All-Out Attack

All-Out Attack is Joker's Final Smash.

Overview
When the Final Smash is used, Joker will rush forward while exclaiming "Ravage them!", and any opponents hit during the initial rush will be placed in the attack. The Final Smash starts by showing Joker, along with three of his fellow Phantom Thieves (either alongside Ann Takamaki, Ryuji Sakamoto and Morgana; or Makoto Niijima, Yusuke Kitagawa and Haru Okumura) in silhouetted form jumping upwards, before a splash screen of all four of them appears. The four of them then rush the enemy at speeds that cause them to turn into blurs, while either Futaba Sakura or Morgana comment on the onslaught. When the attack finishes, Joker lands in front of the opponents, and another splash screen appears with Joker fixing his glove while "The Show's Over" appears next to him.

When "The Show's Over" appears, all captured opponents who are over 100% damage will be instantly KOed; any other captured opponents will instead be dealt additional damage and sent flying. In a Stock or Stamina match, if the move instantly KOing opponents causes the match to end, the match ends on the splash screen without returning to gameplay (along with the announcer's "GAME!" call), persisting onto the victory screen.

If Joker misses the initial rush forward, the player can push the control stick in the opposite direction of Joker to rush backwards and attempt to catch opponents again.
