[2] The Iron Cross Army are sabotaging oil-tankers with the help of their monster, the Sea-Devil, a semi-mechanical anthropomorphic swordfish with an ability to shoot torpedoes from its mouth.

Spider-Man uses his remote controlled Marveller to prevent the Sea-Devil from bombing an industrial complex by making its missiles explode in the air.
