Editing List of SSBU Music (Mega Man series)

A trance-influenced rock remix of the music heard in Ice Man's stage in the original ''Mega Man''. It begins with an arpeggio that builds up from low-pass to high-pass before transitioning to synths and guitar lead.

A remix of Metal Man's stage music from ''Mega Man 2'', and a brief snippet of the title screen music from the same game, as well as a tune similar to “Cannonball” from the ''Mega Man Zero'' series. As befitting the name, it uses a heavy metal style with prominent electric guitars and synths.

A remix of Hard Man's stage music from ''Mega Man 3''. It uses an orchestral rock style with acoustic and electric guitar, along with brass and strings. Near the end of the song, the key is raised by a full step. The electric guitar was performed by Yujin Imanishi.<ref>[https://twitter.com/shotakageyama/status/1072403141306580992 Shota Kageyama on Twitter]</ref>

A medley of various stage themes from ''Mega Man 4'': Dive Man's stage, Skull Man's stage, and Drill Man's stage. The arrangement was supervised by Jun Senoue, a composer for the {{uv|Sonic the Hedgehog}} series; it is performed by his personal band, Sonic Adventure Music Experience, which consists of himself on guitars, Takeshi Taneda on bass, and Akht. on drums.<ref name="jun">[https://nintendoeverything.com/sonic-team-sound-director-on-why-he-chose-mega-man-4-as-his-contribution-to-smash-bros-ultimate/ Sonic Team sound director on why he chose Mega Man 4 as his contribution to Smash Bros.

*According to Jun Senoue, this remix was inspired by the ''[https://megaman.fandom.com/wiki/Worlds_Collide Sonic & Mega Man: Worlds Collide]'' crossover comics by {{s|wikipedia|Archie Comics}}.<ref name="jun"/>

A rock-based remix of Napalm Man's stage music from ''Mega Man 5''. The song goes through three loops, with the last loop raising the key by three semitones. In the middle of the second loop, an additional section is inserted, comprised of a melody from the intro music from ''Mega Man 5'', with the bassline being the Get a Weapon theme from ''Mega Man 5''.

A medley comprising an off-key rendition of Proto Man's whistle (used when the Dark Man robot disguised as Proto Man appears), the Get a Weapon screen music from ''Mega Man 5'', the stage music from the Dark Man's Castle stages, and the intro (which depicts the fake Proto Man kidnapping Dr. Light) and the title screen music from ''Mega Man 5''. The song has a distinct electronic style that uses synth voices reminiscent of the original chiptune music.

A track taken directly from ''Mega Man Zero'', which is itself a remix of Zero's theme from ''Mega Man X''. In the original game, it plays in the intro stage directly after Ciel wakes up Zero.

**However, if one does not count the 2 versions of the Psycho Soldier Theme (one in Japanese, one in English) as separate songs, then ''Mega Man'' has the most overall.
