That comic sucked. The Joes lacked in personality, the story was lacking, the gimmicky stuff like undersea bases and SEA-Legs was just plain goofy and didn't fit in the more realistic (at the time anyway) world of GIJoe (even that large RTV transport they used in the previous two issues was given a realistic explanation)... The other Cobra vehicles were just as silly, the undersea base is just senseless and the Cobras were just WAAAAAAAAAAY too fanatical compared to how they usually are.
The action dialog was hollow, replacing the usual depth of character Hama gave them with typical action hero one-liners ("Sorry I'm late, guys! I took a wrong turn at the last alligator!")...

As a whole, Trimpe was a good artist but a poor writer, as he would again prove when he wrote Special Missions #26 (the Crystal Ball issue).
