Capcom's online store in Japan is selling these Mega Man hoodies. Just looking at them, they appear to be like any other poorly-imagined video game hoodie, straddling the fence between design and cosplay and satisfying neither.
That is, until you fold the arm back.
Oh my God that's a mega buster you can fold out and shoot at cats with. Well, not actually shoot, but shout PEW PEW at.
They're going for ¥14,700. Which, going by the current, inflated exchange rate, is USD$190. Combine that with the fact it's only available on the Japanese site and you're going to have to work for this one.
