Unproduced: Sea Wolf
Pictured above is the unproduced Sea Wolf that would have been released in 1995 as part of the Battle Corps Rangers. It was a recolored version of the 1984 G.I.Joe Killer Whale Hovercraft and would have come with at least one action figure - possible Duke.
Interestingly enough, 1995 would have seen the return of other classic vehicles recolored. The Tactical Battle Platform (1985) was to be recolored and released with two figures - Iceberg and Snow-Viper, while the Mobile Command Center (1987) was to be recolored in more military colors and released.
