M.A.S.K. Piranha

With Sly Rax Action Figure and the Stiletto Mask

About This Vintage Toy

The M.A.S.K. Piranha was released in Kenners first wave of this popular toy line. The Piranha was V.E.N.O.M.’s archetypal bad-guy style motorcycle and was inspired by biker gangs and their notorious members. The modified road bike was driven by the typical-looking 80s biker, Sly Rax, who uses the appropriately named Stiletto mask. The motorcycle with a sidecar transformed into an assault submarine vehicle.


The spring-loaded launch feature for ejecting the submarine was very popular with young children as it brought interactive movable action into imaginary play. When converting the vehicle to attack mode, an action figure can be placed inside the sidecar, and the canopy can be entirely closed for underwater submergence. The powerful water cannons were conveniently positioned to the submarine’s front while the pop-out stabilizer fins were placed on the left and right rear.

Due to the simplicity of this vehicle, the transformation from street motorcycle to sea-ready M.A.S.K. mode attack submarine was relatively quick and straightforward to transform. Similar to the M.A.S.K. Condor V.E.N.O.M.’s Piranha vehicle was also one of the most popular vehicles with young children due to its lower price point than other more extensive and expensive vehicles. It offered an affordable nemesis to any M.A.S.K. collection.

The Stiletto Mask

The Larger Style Mask that Replaced the Original Smaller Version
The Original Smaller Style Mask with No Chest Plate

The Sly Rax action figure featured the Stiletto Mask, which “pretended” to fire harpoons. Kenner’s sarcastic use of the word “pretends” on the packaging ensured the user that the mask itself had no actual powers and the user must pretend that the mask had specific abilities. The smaller mask version shown below was quickly replaced with a larger one that included a slightly extended chest plate. The justification for the change to the more oversized mask was due to a possible choking hazard with children. The original smaller mask version is far rarer to find on the collectors market and is slightly valued. The value of the accessories alone is often worth more than the figure itself, depending on the mint condition of the action figure.

Sly Rax Action Figure

The Sly Rax action figure offered 7 points of articulation with the hips, knees, shoulders, and neck. Due to the overall reduced size of the action figure and to save cost on manufacturing tooling, the M.A.S.K. toy line limited the facial detail on all of the action figures in every series compared to other action figure toy lines produced by Kenner and other competitors. It was thought that consistent mask removal would wear off any painted facial detail paint and that the mask would be on the action figure in most cases during play.

Included Accessories

The M.A.S.K. Piranha included a motorcycle, windshield, sidecar launcher, and side car/submarine. The value of the accessories alone is often worth more than the figure itself, Depending on the mint condition of the collectible.

Original Packaging

Packaging Front
Packaging Back

The original product packaging was a rectangular box with an extended back flap for additional marketing imagery. The packaging also included corrugated inserts to secure the vehicle inside. An illustrated action-based scene, logo, and action figure image appeared on the front of the box, while detailed transformation notations were featured on the back. NOTE: Collectors that have the original card back offer increased value to the collectible. (MWC = Mint with card) If the card back still has a bubble intact, that also increases the value. If the action figure is factory sealed on the original card (MOC= Mint on card), collectors can obtain the most value from that particular item.

Product Instructions

“We Really Do Care!” A bold customer service message Kenner printed on many of the product paperwork included with most Kenners products. Kenner provided detailed hand-drawn instructions on how to operate the vehicle’s features and where to apply the included stickers.
