Darth Vader Transformer Has Identity Crisis

From geekology, Thinkgeek is selling these 11" tall Darth Vader Transformers for $50. For that price you get the main figure along with 3 mini Storm Troopers, 3 little Tie Fighters, and a mini Vader. The figure also comes with a few weapons and makes different noises depending on his mood and what kind of weapons he's holding. Sounds good right? Well there's a problem: It's completely unbelievable. The first Death Star had a diameter between 120 - 160km ( ~75 - 100 miles). That's freaking huge. So if you had a Vader that big, why even bother building a Death Star? Vader could just land on the planet and kick the shit out of any Ewoks that got in the way. Just swing the ol' lightsaber around for a day or two and everyone is dead. Plus you get to keep the planet afterwards instead of vaporizing it. Win, win. That being said, I ordered two of these. One for myself and one for my daughter because I forgot her birthday. I'm hoping she doesn't want it so I can keep one mint in the packaging.
