|This article is about the V.E.N.O.M. transforming motorcycle. For the Cobra submersible, see Piranha (Cobra).|
The Piranha is a special vehicle developed by Project Spectrum. The Piranha is an indigo motorcycle with a weaponized sidecar, able to be launched and convert into a submersible vehicle. Its primary pilot is Sylvester "Sly" Rax.
Sly Rax drove the Piranha into battle against the Transformers Kup and Aileron in Greece, unleashing a set of machine guns from the sidecar. Rax also rode it in M.A.S.K.'s assault on Autobot City, where he was promptly knocked off by Arcee.
During V.E.N.O.M.'s attack on M.A.S.K. in Barbados, Piranha pursued Gloria Baker's Shark until it was halted by the Thunderhawk. During their battle in Toronto, the Piranha and Shark engaged once more. Gloria was able to out-wit Rax by ejecting from her vehicle and attaching a bomb to the side, forcing Rax to eject as the Piranha exploded.
When V.E.N.O.M. was hired to retrieve the head of Astrotrain for Destro, Sly served as backup for Vanessa and Cliff Dagger. When Lifeline attempted to escape, Sly pursued him in the Piranha, forcing his VAMP off the side of a cliff. He then used its sub mode to retrieve Astrotrain's crotch, aided by a group of Iron Grenadiers in Sting Raiders. However, they were thwarted by Gloria and Julio Lopez in the Shark and G.I. Joe member Deep Six in a S.H.A.R.C. While Julio was able to retrieve the piece, Rax used the Piranha to fire at an old naval mine, severely injuring the M.A.S.K. medic.
When V.E.N.O.M. was absorbed into Cobra, Cobra scientist Scrap-Iron rebuilt the Piranha, modifying it to be able to combine with the Warfield's Manta and Sheppard's Rhino to form the giant snake robot King Cobra. After forming the King Cobra in New York City, the mech was ultimately taken down by the G.I. Joe team.
