I gotta say, I'd give the W to Vader. Even putting aside the obvious advantage that the Force gives him, Darth Vader's way more experienced than Drakkon in pretty much every way. Dude's fought two wars as a frontline general, one of them while he was barely older than Tommy was. And he's been trained most of his life in the Jedi arts. Not to mention I'm pretty sure Drakkon is still a child, maybe a bit older than main universe Tommy, but still much younger than Vader would be here.
