Slip-Stream headed a successful air strike on a Cobra base on Grave Island in the Mekong Delta in Vietnam. He was then part of a training mission in Norway that was attacked by Rattlers and a Night Raven. All the Cobra planes were shot down but it was unclear which Joe got the kill on the Night Raven.
Slip-Stream is first seen watching a football game on tv before being told off by Gen. Hawk.
Sometime later, he and a female Strato-Viper shoot each other down over a seemingly deserted island, only to find that it was a lab belonging to Dr. Mindbender, who still has the Cobra base and the escaped mutation within under surveillance.
Appearance: brown helmet with silver goggles; brown mustache; white shirt with dark grey half-vest, brown shoulder guards, and black gloves; white pants with dark grey belt and leg coverings; black shoes and holsters
Variations: the version made in Hong Kong has crisp paint and lighter brown plastic; the version made in China has sloppy paint details, but gains a large, toothy grin.
