Mega Legends

Mega Legends, known as Rockman Special (ロックマンスペシャル) in Japan, is Mega Man's Final Smash in Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate.

Overview
Mega Man uses the Black Hole Bomb to catch the opponents, and then X (Mega Man X), Star Force Mega Man (Mega Man Star Force), Mega Man Volnutt (Mega Man Legends), and MegaMan.EXE (Mega Man Battle Network) all appear alongside the original Mega Man. All of them then use their Mega Busters against the trapped opponents. The screen will focus for a split second on the character being hit, and then the cutscene will end as the character is blasted away.

In Super Smash Bros. Ultimate, Proto Man and Bass also appear in the move, firing the Proto Buster and Bass Buster alongside the blue heroes.

Trophy Description
''For Mega Man's Final Smash, he teams up with all-stars X, MegaMan Volnutt, MegaMan.EXE, and Star Force Mega Man, and they fire their Mega Busters in unison. The Black Hole Bomb fired at the start draws enemies in, and as long as that hits, the Mega Busters will follow. Make your foes see stars!''

Trivia

 * It is interesting to note that the Black Hole Bomb which Mega Man uses in this Final Smash is the only weapon from the digital Mega Man titles (Mega Man 9 & 10) to appear so far.
 * By pressing the Special Button after activation, the Black Hole Bomb can detonate prematurely.
 * It's possible that the name was chosen in reference to the Mega Man Legends series of games.
