This is my concept of what Onslaughts theme could be replaced with if you were playing as Sonic in Marvel Vs. Capcom.
My idea for this one is that this song would play when Sonic is fighting Onslaught (the final boss). It would replace onslaught's normal theme.
The song I used is Live and Learn from Sonic Adventure 2 and I think it would make this fight a lot more epic.
Thanks for watching, comment your thoughts and I hope you enjoy.
