Main Theme plays on the Title Screen of Federation Force, setting the mood for the game. It also played in the E3 2015 trailer where the game was revealed, and latter portions of it played in Mission Briefing and the Story Trailer. Main Theme is also included in Super Smash Bros. Ultimate, where it can be played on any stage from the Metroid series.
Main Theme opens with a series of echoing piano notes in a high register, accompanied by a rapid bass rhythm and various percussive sounds. With a series of drumbeats, the song then transitions into a heroic and cinematic segment, with a melody performed by brass instruments and a harmony performed by orchestral strings. The theme ends with hard-hitting beats on percussion and low brass, accompanied by the same instruments heard at the beginning.

This theme, especially the militaristic fanfare, acts as a recurring leitmotif in Federation Force, with echoes sprinkled throughout the soundtrack. Notable examples include the music tracks for the menu (a slower and deeper version of the theme's intro) and credits (a medley which begins with a slower version of the theme's fanfare).
- Main Theme is one of only three Metroid title themes that does not feature the series's iconic main theme, along with Title from Metroid II: Return of Samus and the piece of piano music from Metroid: Other M.
- The composition of Main Theme resembles that of Theme of Samus. Both themes open with a low bass harmony, transition to a heroic brass melody, and end with heavy drumbeats.
- In the August 8, 2018 Nintendo Direct, Main Theme was titled Splash Screen in the Ultimate Sound Test, referring to the Title Screen where it is played. This was changed before the release of Ultimate, but it is still named d20_pff_splashscreen.lopus in the internal files.
