Unreleased
Revealed at OTFCC 2004, Piranhaking was to be a Wal*Mart exclusive set, a redeco of the Generation 1 Seacons for the Energon line. However, Wal*Mart ended up passing on the exclusive, likely to to low sales of previous exclusives to the chain. (Though in all fairness, Wal*Mart had almost a half-dozen different Universe exclusive toys come out in the span of a month.) This was one of several proposed exclusive toys that ended up in development limbo during that year.
At this time, there are no concrete plans to release the set, though at BotCon 2005 Hasbro representatives said they were still trying to find an outlet for it. It is possible that the set might see release through the Fun Publications Transformers Collectors' Club, as that venue had saved Spacewarp from limbo.
This mold set was also used to make God Neptune and King Poseidon.
