Sea Attack is one of four Adventure Packs released only in Europe. The sources do not give a release year for the European group.
The agent is Hondo “Striker” MacLean. Wikipedia describes the gear as a small attack boat. The fan site MASKFORCE lists a sea sled that skims across the water like a hydroplane, an aqua lung, two fog pitchers and a harpoon, with the harpoon and fog pitchers as the weapons system.
MacLean wears a recolored Blaster II mask, which MASKFORCE says fires supersonic laser rays. Blaster II is the improved heat beam that comes with Hurricane.
The sources used here do not record a cartoon appearance for the pack itself. MacLean debuts in the first episode, “The Deathstone,” and drives Firecracker, then Hurricane. MASKFORCE lists MacLean as 32 and a weapons specialist and tactical strategist, with a civilian job as a high school history teacher. Doug Stone voices him.
