Tomoya Ohtani on Sonic Lost World Original Soundtrack:

The Deadly Six Theme

This is the original of The Deadly Six Theme. I had the request of wanting to use the same music for all the battles of the Deadly Six from Director Kishimoto and was aware of making the music that would seem to withstand in high frequency usage. They are boss battles, so they have tension, fearfulness, as well as others, but I mixed the enjoyment for game, the natures of the Deadly Six characters, and so on, and it became the music like this.
