Vypra is an interesting little situation.
In 1998, Hasbro recovered the molds for Jinx and the Stinger jeep.
But they didn't have the trademarks for their names.
Hence, Jinx was redone in grey and renamed Vypra; she was then packed in with the Rattler Jeep, the new name for the Stinger.
When life hands you lemons, I guess...
