Like the choice you used for Serpentine's boss theme as well: threatening, but still feels goofy enough. Just like Serpentine, fits how he's somewhat of a threat in this part of the story, but he's still a character that everyone else basically treats as a joke.

and i thought i would be the only one is by the soundtrack reminded on metallic madness

Bad future would fit more in my opinion

and that stage is very similar to that of megaman x6 arriving against the sigma boss

I'm glad someone else noticed inversion dynamo and metallic madness had similar music

Can you do sonic cd USA🇺🇸 soundtrack on freedom planet 1 please
