Hearing that Cobra was testing deadly new Sonic Weapons, Hawk wanted to personally handle this. He equips himself with a Sonic absorbing flight suit, dual thrust hyper-sonic jet pack with two air-to-surface missiles and a gyro-stabilizer. He's also armed with a rapid fire sonic pulse cannon.
He's ready to put the sonic hurt on Cobra and cripple their operation!
Hawk's helmet is equipped with HUD threat warning system, voice activation and control over jet pack and targeting range finder.

With this custom I wanted to somewhat resemble his '91 version, which I always thought was a wicked cool figure. The color scheme is similar but a little brighter in keeping with my Sonic Fighter theme.
The padding from the Hawk arms and legs, and the Countdown torso really worked well together.
The helmet is from a ROC Firefly, so I had to sand down the inside and even cut a little from the back to get it to fit comfortably over the head.
The jetpack is a Metal Head backpack with wings from a Stealth Fighter missile and a Metal Head thigh mounted rocket launcher.
