well if i was an evil boss. before choosing the music, i wold proboly need to picture what kind of boss i would be. knowing me i would proboly not have any super powers but instead i will utilise powers of technology at my disposal. and i would proboly have a lot of destructive technology to crush my enemies. most likeley they will be more or less normal stuff like battletanks and gunships which i modded up with high tech experimental weapons and other high tech... tech things. this stuff will be so modded and pimped it would be hard to recognise the original gunship/tank its made out of. Myabe i will even have a few cybernetic limb replacements and implants and will have a sidekick battle droid who is even more dangerous than me. as for music. thats really hard. the only music i can think of now is this. but thats kinda already taken because its already reserved for another evil villan. and it doesent suit well for end of the game boss.
here it is
If anyone has any better music for me hit me up yo
