Bio

Sly Rax, codename Wrecker, is a V.E.N.O.M. agent in sunglasses who rides the Piranha, a purple BMW motorcycle with a sidecar that doubles as a submarine. His mask is Stiletto, which fires armor-piercing harpoons. Mark Halloran voices him.

Sly Rax is a V.E.N.O.M. mercenary who wears sunglasses and is credited with weapons and espionage skills; a different source calls him a con artist. Mark Halloran voices him, as he does Cliff Dagger, Buddie Hawks, Ace Riker and Duane Kennedy.

His vehicle is Piranha, a purple BMW motorcycle whose sidecar doubles as a submarine. Its mask, Stiletto, fires armor-piercing harpoons. Piranha is in the first episode and was among the first-series Kenner toys, packed with Sly. A second vehicle is Pitstop Catapult, a fueling station that becomes a catapulting grinder with the Sawblade mask.

In the cartoon he comes across as lazy and resentful of Miles’s favorites. The 1987 DC comic has him wanting to replace Miles. A fan site records him driving a V.E.N.O.M. tractor trailer with Cliff Dagger in the episode Vanishing Point.

What does Sly Rax ride?
Piranha, a purple BMW motorcycle whose sidecar turns into a submarine. It carries the Stiletto mask, which fires armor-piercing harpoons.
Does Sly want to replace Miles?
The 1987 DC comic says so, and the M.A.S.K. wiki credits him with a hidden ambition to take Miles's place. In the cartoon he shows resentment of Miles's favorites more than any open move.
Is there a new Piranha toy?
The Loyal Subjects released it in 2026 as the Stealth Submarine Cycle, on its [toy page](/toys/stealth-submarine-cycle-the-loyal-subjects-2026/). The 1985 Kenner Piranha is the vintage version.
