He may not be the hero in our eyes, but he is in his own story. In his eyes, he is fighting for control of the power to save his kind. The Cybertronians are aliens to us, however we are also aliens to them. The decepticons may not care to save Earth over Cybertron, for they are not native here. But If we were in their place, we’d likely attempt to destroy Cybertron in order to save Earth. He’s the hero of his own world-saving mission, hence the heroic theme for what we see as a villainous character.
Bizzarely, it actually is the case of real life. Us human tend to destroy other things, whether its forests, or the ocean, or soon in the future, other planets, just to sustain ourselves. All these mirrors the Decepticons destroying other's home to save theirs.
Ditto on that. It's like you're in a gigantic ship or mechanism (or something) that's slowly reactivating after centuries of being dormant, and you're urgently making your way through the structure to find and confront the person who's starting everything back up.
Senator Shockwave has always and only thought he's doing what's right. The tragedy is what was done to him, and how that warped his perceptions of what 'right' really is.
Earth isn't a hazardous gas giant, has good gravity, already had the proudstar on it to cyberform, and has infrastructure to cyberform. Also Earth occasionally has energon on it.
This theme sounds simultaneously lame and cool at the same time. Compared to the epicness of Motormaster's theme or the hectic pace of Starscream's, this one just sounds a tad...generic in comparison. Nonetheless, it is quite impressive. And it also makes sense thatt the cold, emotionless, bland Shockwave would get so nondescript a theme.
