I'll rarely cover cosplay around here, but I'm not above making exceptions for truly exceptional work. Brazilian Thaís Jussim has pretty much earned some attention. As you can see above, she's manufactured what is basically the best Metroid cosplay ever.
Jussim's model of the Varia Suit weighs 23 pounds and cost $350 to manufacture from parts as diverse as polystyrene, automotive paint, and a motorcycle helmet. The costume's design is based on the more realistic version of the Varia Suit seen in Metroid Prime for the GameCube (and coming soon for Wii), and is even loaded with 73 working LED lights for extra atmosphere. No, it doesn't have a Morph Ball option, but I almost wouldn't be surprised if it did.
You can check out a gallery of Jussim in the Varia Suit and some of her other costumes at DeviantArt, and read a great interview with her about the construction of the suit at the Metroid Database.
