On the right: Japan's new E-Tank energy drink, released to commemorate Rockman 10 in 2010.
As you can tell just by looking at the glasses, the new version is different from the old, despite the similar-looking cans. Whereas the old was royal jelly-flavored, the new is a little more mundane with the simple flavor of blueberries.
ProTip: They're called blueberries because they're blue.
For a limited time, the energy drink is being sold for the low, low price of ¥137, or $1.24 USD. Of course, to take advantage of such a deal, you must live in Japan. Otherwise, you're stuck trying to order the less-iconic American version from the likes of Amazon.com or ToyWiz for $3.99 a pop.
For the collectible-minded, you can compare the old and new cans by way of the pictures shown here on Kotobukiya.
Just for fun, we know that E-Tanks are but one of many kinds of tanks in the Mega Man universe, and we've seen it come in two flavors so far. Supposing other tanks were to be made-- S-Tanks, W-Tanks, M-Tanks, even Sub-Tanks-- what flavors do you think would best suit such energy drinks? Share your flavor fantasies in the comments below.
