Jetbug strikes me as the Bitil of the Hero Factory universe -- a flying, yellow, insectoid villain hell-bent on causing a lot of trouble for the good guys. It's a cool set with probably the most useful aesthetic MOC-making pieces of any of 'em. The translucent neon orange armor pieces are especially juicy & intriguing, though the dark pearl gray weapon pieces used on both hands and for the mandibles are also great pieces.
The one thing I don't like about Jetbug is the two-sided head, which has Nitroblast's face on the back. On Nitroblast, the Jetbug face wasn't too obvious, but the reverse is a different story. Like with Drilldozer & Fire Lord, turn this guy around, and you have another very clear face staring directly at you. Lego, please never again do this with masks. If you're going to double them up, do it in such a way that the rear-facing face is completely out of sight. Thanks.
