Well, you just transported me to the 80's... Those sick electric guitars and drums: cowabonga, dude. Too epic.
Also, it's a leit motif alright. The melody is a bit crazy all over the place, but I think it works; there's a clear pattern there. And it has enough hard metal and minor key to fit a villain theme. Good job *thumbs up* I would like to listen to the whole thing if you ever continue it.
